how to add a text at the bottom of jspdf auto table in angular5 - angular5

I am using jspdf auto table in my angular5 app. I am generating dynamic data for jspdf auto table. My problem is how can I add a text at the bottom of table?
const columnHead = [];
const columnRow = [];
this.tableColumns.filter(x => {
columnHead.push(this.capFirstLtr(x.title));
});
this.tableData.filter((x, y) => {
x.slaMetFlag = (this.mapData[y].slaMetFlag ? this.capFirstLtr(this.mapData[y].slaMetFlag) : '-');
columnRow.push([x.date, x.slaMetFlag, x.srType, x.srID, x.srStatus, x.aof, x.ppm, x.deviceID, x.siteID, x.branchID]);
});
const doc = new jsPDF();
doc.text('Showing data from ' + moment(this.requestApi.fromDate).format('MM/DD/YYYY') + ' to ' + moment(this.requestApi.toDate).format('MM/DD/YYYY'), 5, 10);
doc.autoTable(columnHead, columnRow, {
styles: { overflow: 'linebreak', halign: 'center', fontSize: 7},
tableWidth: 200,
margin: 5,
theme: 'grid',
startY: 15,
addPageContent: function(data) {
console.log('data', data);
}
});
doc.save('SR View Export');
}
in the above code how can I add a text after the completion of jspdf auto table?

If you want to know something about the last table that was drawn you can use doc.autoTable.previous. It has a doc.autoTable.previous.finalY property among other things that has the value of the last printed y coordinate on a page. This can be used to draw text, multiple tables or other content after a table.
doc.autoTable.previous.finalY use this property.
doc.autoTable(headers, data);
let finalY = doc.autoTable.previous.finalY;// The y position on the page
doc.text(20, finalY, "Hello!")

How to edit PDF file which is exported with jspdf.min.js?

Don't know if the question is well put, but here is my problem: I managed to export my chart to PDF format using jspdf.min.js through this piece of code:
$("#generate").on("click", function (e) {
html2canvas($("#placeholder").get(0), {
onrendered: function (canvas) {
var imgData = canvas.toDataURL('image/png');
console.log('Report Image URL: ' + imgData);
var doc = new jsPDF('portrait');
doc.addImage(imgData, 'PNG', 10, 10, 190, 95);
doc.text("TEST TEXT");//I tried to add a text in PDF file,but didn't work
doc.save('sample-file.pdf');
}
});
});
Is there a way to add a title of my chart in the PDF file?
Try this example. Is a trick which might help you. Don't forget to update your options:
var options = {
canvas: true,
grid: {
margin: {
top:50
},
}
};

OpenLayers 3 - draw polyline vertices only

I'm using OpenLayers 3 and I need to show only the vertices of a polyline. For exemple see this image :
I want to be able to show only the red squares (they can be something else than squares, like circles). Using markers is not an option for performance issue, my lines can be huge (500 000 vertices).
Currently I have a working code :
// Define the style for vertex polyline :
var yellowVertexPolylineStyle = [
new ol.style.Style({
image: new ol.style.Circle({
radius: 1.5,
fill: new ol.style.Fill({
color: 'yellow'
})
}),
geometry: function(feature) {
return new ol.geom.MultiPoint(feature.getGeometry().getCoordinates());
}
})
];
// Create the line :
var lineLayer = new ol.layer.Vector({
zIndex: 1000,
source: new ol.source.Vector({ features: [new ol.Feature({ geometry: myLine })] }),
style: yellowVertexPolylineStyle
});
// Add the layer :
map.addLayer(lineLayer);
But this is causing performance issue when the polyline is quite big (> 10 000 points).
Using an ol.geom.MultiPoint geometry is even worse. Does someone knows a better way?
EDIT : I'm trying this now :
// Define the style for vertex polyline :
var yellowVertexPolylineStyle = [
new ol.style.Style({
image: new ol.style.Circle({
radius: 1.5,
fill: new ol.style.Fill({
color: 'yellow'
})
}),
geometry: function(feature) {
var geom = feature.get('stylegeom');
if (!geom || (geom && geom.getCoordinates().length !== feature.getGeometry().getCoordinates().length) ) {
geom = new ol.geom.MultiPoint(feature.getGeometry().getCoordinates());
feature.set('stylegeom', geom);
}
return geom;
}
})
];
I'll come back here to tell if it works...
You need to cache your style geometry, otherwise it will be calculated for every rendered frame, e.g.
geometry: function(feature) {
var geom = feature.get('stylegeom');
if (!geom) {
geom = new ol.geom.MultiPoint(feature.getGeometry().getCoordinates());
feature.set('stylegeom', geom);
}
return geom;
}
If your feature geometry changes, you'll need to update the style geometry too:
source.on('changefeature', function(evt) {
feature.set('stylegeom', undefined);
});

OnClick() with Highcharts in MVC 4

I'm a coop student and I'm working with Highcharts in MVC 4. My employer would like to be able to click on a column on a Column chart and have it take the user to a new page. Does anyone have any ideas on how to do this?
I'm having a hard time finding examples of Highcharts in MVC, so if someone has some good resources please send them my way.
Thanks to the comment and the resource here I was able to solve my own problem. My view takes in a Highcharts object as the model, and when my Controller passes it the following Highcharts object it works:
new Highcharts("chart")
//define the type of chart
.InitChart(new Chart { DefaultSeriesType = ChartTypes.Column})
//overall Title of the chart
.SetTitle(new Title { Text = chartTitle })
//small label below the main Title
.SetSubtitle(new Subtitle { Text = subTitle })
//load the X values
.SetXAxis(new XAxis { Categories = xAxisData })
//set the Y title
.SetYAxis(new YAxis { Title = new YAxisTitle { Text = yAxisTitle } })
.SetTooltip(new Tooltip
{
Enabled = true,
Formatter = #"function() { return '<b>'+ this.series.name +'</b><br/>'+ this.x +': '+ this.y; }"
})
.SetPlotOptions(new PlotOptions
{
Line = new PlotOptionsLine
{
DataLabels = new PlotOptionsLineDataLabels
{
// this makes the value of the dot appear above it if it is set to true (for Line charts)
Enabled = true
},
// set to true so that when the user hovers their mouse over a column/dot it's value and name will appear
EnableMouseTracking = true
},
/***********
* IMPORTANT PART
************/
Series = new PlotOptionsSeries
{
Point = new PlotOptionsSeriesPoint
{
Events = new PlotOptionsSeriesPointEvents
{
// Here you can put code for different event handlers (like Click and MouseOver) in javaScript.
// The one below makes an alert box pop up with the name of the column and its value when a
// column is clicked
Click = "function () {alert('Category: ' + this.category + ', value: ' + this.y);}"
}
}
}
})
//load the Y values
.SetSeries(yAxisData.ToArray());
Defaulty in the highcharts you should catch click event on serie's point.
plotOptions: {
series: {
cursor: 'pointer',
point: {
events: {
click: function () {
alert('Category: ' + this.category + ', value: ' + this.y);
}
}
}
}
},
Check that wrappers for asp.net supports that option.

FullCalendar and Flot Resize Conflict

I've successfully integrated both a Flot line graph and an instance of FullCalendar into my site. They are both on separate pages (although the pages are loaded into a div via AJAX).
I've added the Flot Resize plugin and that works perfectly, re-sizing the line graph as expected. However, it seems to cause an error when resizing the calendar.
Even if I load the calendar page first, when I resize the window I get this error in the console (also, the calendar does not resize correctly):
TypeError: 'undefined' is not an object (evaluating 'r.w=o!==c?o:q.width()')
I was struggling to work out where the error was coming from, so I removed the link to the Flot Resize JS and tried again. Of course the line graph does not resize, but when resizing the calendar, it works correctly.
The div containers for the two elements have different names and the resize function is called from within the function to draw the line graph (as required).
I have tried moving the link to the Flot Resize plugin into different places (i.e. above/below the fullCalendar JS, into the template which holds the graph), but all to no avail.
Does anyone have any idea where the conflict might be and how I might solve it??
Thanks very much!
EDIT: It seems that the error is also triggered when loading the line graph (flot) page AFTER the fullcalendar page even without resizing the window.... Now I am very confused!
EDIT 2: The code which draws the line graph. The function is called on pageload and recieves the data from JSON pulled off the server. When the graph is loaded, I still get the error about shutdown() being undefined.
function plotLineGraph(theData){
var myData = theData['data'];
var myEvents = theData['events'];
var myDates = theData['dates'];
var events = new Array();
for (var i=0; i<myEvents.length; i++) {
events.push(

}
);
}
function showTooltip(x, y, contents) {
$('<div id="tooltip">' + contents + '</div>').css( {
position: 'absolute',
display: 'none',

border: '1px solid #fdd',
padding: '2px',
'background-color': 'black',
opacity: 0.80
}).appendTo("body").fadeIn(200);
}
var previousPoint = null;
$("#placeholder").bind("plothover", function (event, pos, item) {
$("#x").text(pos.x.toFixed(2));
$("#y").text(pos.y.toFixed(2));
if ($("#enableTooltip:checked").length == 0) {

if (previousPoint != item.dataIndex) {
previousPoint = item.dataIndex;
$("#tooltip").remove();

$('#placeholder').resize();

}
EDIT 3:
The calendar is called like this:
function showCalendar() {
var date = new Date();
var d = date.getDate();
var m = date.getMonth();
var y = date.getFullYear();
$('#fullcalendar').fullCalendar({
header: {
left: 'prev',
center: 'title',
right: 'next'
},
clickable: true,
firstDay: 1,
eventSources: [
{
url: '/populate-calendar/{{theProductUuid}}/',
color: 'black',
data: {
text: 'text'
}
}
],
eventClick: function(calEvent, jsEvent, view) {
var startDate = $.fullCalendar.formatDate(calEvent.start, 'yyyy-MM-dd');
var endDate = $.fullCalendar.formatDate(calEvent.end, 'yyyy-MM-dd');
var eventId = calEvent.uuid;
$('#modal-event-title').text(calEvent.title);
$('#edit-event-name').val(calEvent.title);
$('#edit-start-date').val(startDate);
$('#edit-end-date').val(endDate);
$('#edit-event-text').val(calEvent.text);
$('#edit-event-btn').attr('data-uuid', eventId);
$('#modal-edit-event').on('click', '#delete-btn', function(){
deleteCalendarEvent(eventId);
});
$('#modal-edit-event').modal();
},
});
}
The AJAX to load the page containing the flot chart:
function loadDetailedReports(uuid){
$('#product-content').fadeOut('slow', function(){
$('#product-content').empty();
$('#whole-product-sub-nav .active').removeClass('active');
$('#detailed-reports-content').load('/detailed-reports/' + uuid + '/', function(){
$('#detailed-reports-btn').addClass('active');
$('#detailed-reports-content').fadeIn('slow', function(){
if (authorized){
setLocationHash('loadDetailedReports&' + uuid);
getChartData(uuid);
} else {
setLocationHash('');
}
});
});
});
}
And the AJAX to load the page containing the calendar:
function loadCalendar(uuid){
$('#detailed-reports-content').empty().hide();
$('#product-content').fadeOut('slow', function(){
$('#whole-product-sub-nav .active').removeClass('active');
$('#product-content').load('/calendar/' + uuid + '/', function(){
$('#calendar-btn').addClass('active');
$('#product-content').fadeIn('slow', function(){
if (authorized){
setLocationHash('loadCalendar&' + uuid);
} else {
setLocationHash('');
}
showCalendar();
});
});
});
}
The calls to .resize and .shutdown are there because I was under the impression that they are necessary to achieve the resizing function and in response to your earlier comment regarding shutdown...... They're quite possibly n00b errors........?!?!
It looks like this is triggering on line 198 of jquery-resize:
data.w = w !== undefined ? w : elem.width();
This sounds like a race-condition stemming from the way you load different content into the same div. Flot binds the resize event to the chart div, and only un-binds it if the plot is destroyed cleanly.
EDIT: Looking at your code, my first suggestion would be to get rid of the resize and shutdown calls at the end of plotLineGraph. The resize plugin doesn't require any setup; it hooks into Flot to attach automatically to any new plot. So your call to resize is actually to jQuery's resize event trigger, which may be what's causing the error.
EDIT #2: I'm still not clear on your structure, but to generalize: anywhere that you might be getting rid of #placeholder (via emptying its parent or anything like that) you should first call shutdown on the plot object. If you aren't keeping a reference to it, you can do it like this: $("#placeholder").data("plot").shutdown(); but then have to account for the fact that it's undefined prior to the creation of your first plot.
If that still doesn't work, I'd need to see a live (simplified) example to make any further suggestions.

Attaching an Event Listener

I've just finished creating a meticulously generated grid of icons (imageViews) and now I need to be able to do something with them. What I'm finding, though, is that the event listener I'm trying to bind isn't getting bound. Window loads, my icons are displayed nicely, but they aren't clickable.
Can anyone see what I'm missing? The code below is a fully functional (except for the part that doesn't function) file. You should be able to copy it into a test app and load it right up (may be iPhone-only at the moment).
Any insight would be much appreciated.
// this sets the background color of the master UIView (when there are no windows/tab groups on it)
Ti.UI.setBackgroundColor('#000');
//
// create base UI tab and root window
//
var win = Ti.UI.createWindow({
backgroundColor:'#fff',
layout: 'vertical',
navBarHidden: true,
});
// icon grid
var icons = [
{ image: '/images/ico_generic.png', label: 'Hospital Locations', url: 'http://google.com' },
{ image: '/images/ico_generic.png', label: 'Tobacco Free Campus', url: 'http:://robwilkerson.org' },

{ image: '/images/ico_generic.png', label: 'Patient Forms', url: 'http://github.com' }
];
// put the grid in a scrollable view
var iconGrid = Ti.UI.createScrollView({
layout: 'vertical',
});
// incoming properties we want customizable
var cols = 3;
var icoW = 57;
var icoH = 57;
// Grid
var xSpacer = 10; // horizontal space b/t icons
var ySpacer = 10; // vertical space b/t icons
var rows = Math.ceil( icons.length / cols ); // how many rows?
// Container width = 1/3 of the viewport minus the icon widths and spacers
var containerW = Math.floor( ( Ti.Platform.displayCaps.platformWidth - ( xSpacer * ( cols + 1 ) ) ) / 3 );
// Container height = icon height + label spacer + label height
var containerH = icoH + ySpacer + 15;
// Row height = icon height + top spacer + bottom spacer + label spacer + 15 (label height)
var rowH = containerH + ( 2 * ySpacer );
// Incrementing values
var i = 0;
var viewHeight = 0;
for( var y = 0; y < rows; y++ ) {
var thisRow = Ti.UI.createView({
className: 'grid',
layout: 'horizontal',
height: rowH,
touchEnabled: false,
});
viewHeight += rowH;
for( var x = 0; x < cols && i < icons.length; x++ ) {
var container = Ti.UI.createView({
left: xSpacer,
height: containerH,
top: ySpacer,
width: containerW,
});
var icon = Ti.UI.createImageView({
left: ( containerW - icoW ) / 2,
height: icoH,
image: icons[i].image,
top: 0,
width: icoW,
});
var label = Ti.UI.createLabel({
// borderColor: '#00f',
font: { fontSize: 12 },
height: 15,
text: icons[i].label,
textAlign: 'center',
top: icoH + ySpacer,
width: containerW,
});
icon.addEventListener( 'click', function( e ) {
alert( 'Icon ' + i + ' was clicked' );d
});
container.add( icon );
container.add( label );
thisRow.add( container );
i++;
}
iconGrid.add( thisRow );
iconGrid.height = viewHeight;
}
win.add( iconGrid );
win.open();
You can also apply an event listener to the "view" itself. The reason being is, if you constantly add the same event listener to every single view, you'll cause the device's memory to become smaller and smaller, especially in cases where you'll have a larger data set.
My suggestion to you is this:
Add your own property to the imageView, like an "id" or something. So something like:
Ti.UI.createImageView({image: 'path/to/image.png', id: 'array_key'});
Once you've done that, you can add an event listener to the parent view, in this case your imageView.
view.addEventListener('click', function(e) {
alert(e.source.id + ' was clicked');
});
That way you have one event listener that can handle all the imageView events.
This one's on me. In my learning process, I went through a couple of different solutions to display a grid of icons. In one of the early iterations, I had to disable touch for the row (it was a tableView attempt). Several iterations later I got the display right, but disabling touch access on the row killed my ability to "click" the icons.
I was so far down the road that I didn't even realize that property was still in place until a new set of eyes pointed it out to me. Once I removed that property on thisRow, the event listeners got bound properly.
I am adding some line of code. What I have done is like created the grid of images and when you click, you will be able to that image.

It was response I was getting from the server.
Now for Making it is in grid and for clickable image, I am going to paste the code below. Note grid is done for 320 px width.

var response = JSON.parse(this.responseText);
var myObjectString = JSON.stringify(response);
Titanium.API.info('myObjectString--->: ' + myObjectString)
var myArray = response.body;
var objectArray = [];
var k = 5;
for (var i = 0; i < myArray[0].photos.length/5; i++) {
var l = 0+i*5; var m = 0 for (var j = l; j < k; j++) {
var thumb = Ti.UI.createImageView({
image:myArray[0].photos[j].thumbnail,
largeImage:myArray[0].photos[j].photo,
height:60,
tag:j,
width:60,
top:5*(i+1)+60*i,
left:3*(m+1)+60*m,
});
objectArray.push(thumb);
m++;
scroll.add(thumb);
thumb.addEventListener('click' ,function(e)
{
for(var i =0;i<objectArray.length;i++)
{
if(e.source.tag==objectArray[i].tag)
{
var LargeImageView = Ti.UI.createWindow({
