I have an array of elements like this:
[
'AKH-123': { ignition: true, position: { lat: 0, lng: 0}, },
'VAW-123': { ignition: true, position: { lat: 1, lng: 1}, }
]
I want to show them using vfor. I have tried this:
<gmap-marker
:key="m.vehicle"
v-for="(m, index) in vehicles"
:position="vehicles[index].position"
:icon="{url: getImagePath(m.ignition), scaledSize: new google.maps.Size(24, 24)}"
v-if="show_live_vehicles"
>
</gmap-marker>
But this won't show vehicles on map. I am using vue2-google-maps component. I don't understand how do I pass in positions from keyed array
change this part of your code: new google.maps.Size(24, 24) to this new google.maps.Size(m.position.lat, m.position.lng) or reverse the parms depending on the api.
This: vehicles[index].position could also just be m.position given that the two are equivalent.

I'm using react-native-charts-wrapper for creating a chart and I was wondering if there is a way to change the x-axis label style for just one bar? I have a whole week in the chart and I want to change the color of the current day. So if today is Monday I just want the M to be a different color. I don't want to change the color of the bar, just the letter under it.
These are settings for xAxis:
xAxis: {
drawAxisLine: true,
drawGridLines: false,
position: 'BOTTOM',
labelCount: 7,
valueFormatter: ['M', 'T', 'W', 'T', 'F', 'S', 'S'],
textColor: formatedColor,
axisMinimum: -1,
axisMaximum: 7,
avoidFirstLastClipping: true,
},
I checked the documentation and properties but couldn't find anything.
I think I know
core:google.charts.load('current');
ChartType: ColumnChart;
Don't use the bar
google.charts.load('current');
google.charts.setOnLoadCallback(drawVisualization);
function drawVisualization() {
var wrapper = new google.visualization.ChartWrapper({
chartType: 'ColumnChart',
dataTable: [
['Element', 'Density', { role: 'style' }],
['Copper', 8.94, '#b87333'],
['Silver', 10.49, 'silver'],
['Gold', 19.30, 'gold'],
['Platinum', 21.45, 'color: #e5e4e2' ],
],
options: {'title': 'Countries'},
containerId: 'columnchart_values'
});
wrapper.draw();
}
I create a line chart using dojo. Recently, I have been applying multiple axis on the chart. But there was a problem here. It is applied to multiple axes in one place I have raised the issue of overlapping tick value. and do not change the properties of leftBottom, is there a way to adjust the shaft position? For example, x: 10, y: 20?
my code
var axisXRef = {labels : labelsample, titleOrientation : "away", stroke : {}, natural : true};
var axisYRef = {vertical : true, stroke : {}};
var chart = new Chart("chartNode");
chart.addPlot("lines", { type: Lines, tension: 3 ,min:0});
chart.addPlot("stacklines", { type: StackedLines, tension: 3 ,hAxis:"x",vAxis:"y1"});
chart.addPlot("areas", { type: Areas, tension: 3,hAxis:"x",vAxis:"y2" });
chart.custom.axisX = lang.clone(axisXRef);
chart.custom.axisY = lang.clone(axisYRef);
chart.addAxis("x", chart.custom.axisX);
chart.addAxis("y", chart.custom.axisY);
chart.addAxis("y1", {
vertical: true,
min : 50,
max:70,
leftBottom:true,
majorLabels: true, majorTicks: true, majorTick: {color:"red",length:50},
minorLabels: true, minorTicks:true, minorTick:{color:"red",length:50},
microTicks: true, microTick:{color:"red",length:50},
fixUpper: "major",
fixLower:"minor"
});
chart.addAxis("y2", {
vertical: true,
min : 0,
max:49,
leftBottom:true,
majorLabels: true, majorTicks: true, majorTick: {color:"blue",length:25},
minorLabels: true, minorTicks:true, minorTick:{color:"blue",length:25},
microTicks: true, microTick:{color:"blue",length:25},
fixUpper: "major",
fixLower:"minor"
});
Unfortunately Dojo charting only supports two axis per direction both axis being on different side of the chart. In other words you can't have two axis both on the left side of the chart. You have to have one right side using leftBottom: false property.
I try to change dynamically the plotBackgroundColor of my chart (after the highcharts generation). Before, and for a lot of attributes, I used (examples):
chart.options.plotOptions.bar.dataLabels.format = '{y} meters'; \n";
chart.options.tooltip.valueSuffix = 'meters'; \n";
So, with the same way, I want to change my plotBackground :
var gradient = {
linearGradient: [0,400,0,0],
stops: [
[0, 'yellow'],
[1, 'black']
]
};
chart.options.chart.plotBackgroundColor = gradient;
But it doesn't work... Someone has an idea ?
Highcharts v5+
Use chart.update(). Demo: https://jsfiddle.net/BlackLabel/p5juc3no/1/
Snippet:
chart.update({
chart: {
plotBackgroundColor: 'transparent'
}
});
Older versions of Highcharts:
Use element.attr() function: http://jsfiddle.net/3bQne/204/
Code:
chart.plotBackground.attr({
fill: 'white'
});
I have a working chart with Dojo 1.8.
chart1 = new dojox.charting.Chart2D("chart1");
chart1.addPlot("default", {type: "Lines", ...
chart1.addSeries("Series A", [{ x: 1, y: 2.3, tooltip: "Value 1"}, ...
My data from the series gets displayed correctly as line and the whole line (series) gets the color 'Green'.
I know how to change the color for the whole series, but would it be possible that the line changes its color based on the data values? Lets assume the x-axis is a time axis and I need the line (series) to be green for until today, and then red for the future values.
Would this be possible and how ?
(I am using markers for the values. If these could change based on the value it would be enough)
I found something something like this in the documentation:
chart.addSeries("Series A", [
{y: 4, color: "red"},
{y: 2, color: "green"},
{y: 1, color: "blue"},
{y: 1, text: "Other", **color: "white", fontColor: "red"**}
]);
But it only works for PIE-charts and not for LINES-charts.
Thank you in advance.
You could try this http://jsfiddle.net/jUS54/
Use styleFunc in the addPlot method for change the markers colors:
var chart1 = new Chart("simplechart");
chart1.addPlot("default", {type: Lines, markers:true, styleFunc: function(item {
if(item <= 2){
return { fill : "red" };
}else if(item > 3){
return { fill: "green" };
}
return {};
}});
You can change the color by adding 'fill' to your chart data. Basically, loop through your input data deciding what to set your fill too while constructing the JSON for chartData.
var chartData = [{y: 10000,fill: "red"},{y:9200,fill: "yellow"},{y:11811,fill: "green"},{y:12000,fill: "blue"},{y:7662,fill: "blue"},{y:13887,fill: "black"},{y:14200,fill: "gray"},{y:12222,fill: "purple"},{y:12000,fill: "green"},{y:10009,fill: "purple"},{y:11288,fill: "green"},{y:12099,fill: "blue"}];

May I know if it is possible to put pictures or images into the rows of DataTables (http://datatables.net/) and how does one goes in doing it?
yes, simple way (Jquery Datatable)
<script>
$(document).ready(function () {
$('#example').dataTable({
"processing": true, // control the processing indicator.
"serverSide": true, // recommended to use serverSide when data is more than 10000 rows for performance reasons
"info": true, // control table information display field
"stateSave": true, //restore table state on page reload,
"lengthMenu": [[10, 20, 50, -1], [10, 20, 50, "All"]], // use the first inner array as the page length values and the second inner array as the displayed options
"ajax":{
"url": "#string.Format("{0}://{1}{2}", Request.Url.Scheme, Request.Url.Authority, Url.Content("~"))/Home/AjaxGetJsonData",
"type": "GET"
},
"columns": [
{ "data": "Name", "orderable" : true },
{ "data": "Age", "orderable": false },
{ "data": "DoB", "orderable": true },
{
"render": function (data, type, JsonResultRow, meta) {
return '<img src="Content/Images/'+JsonResultRow.ImageSrcDB+'">';
}
}
],
"order": [[0, "asc"]]
});
});
</script>
[edit: note that the following code and explanation uses a previous DataTables API (1.9 and below?); it translates easily into the current API (in most cases, just ditch the Hungarian notation ("fnRowCallback" just becomes "rowCallback" for example) but I have not done so yet. The backwards compatibility is still in place I believe, but you should look for the newer conventions where possible]
Original reply follows:
What Daniel says is true, but doesn't necessarily say how it's done. And there are many ways. Here are the main ones:
1) The data source (server or otherwise) provides a complete image tag as part of the data set. Don't forget to escape any characters that need escaping for valid JSON
2) The data source provides one or more fields with the information required. For example, a field called "image link" just has the Images/PictureName.png part. Then in fnRowCallback you use this data to create an image tag.
"fnRowCallback": function( nRow, aData, iDisplayIndex, iDisplayIndexFull ) {
var imgLink = aData['imageLink']; // if your JSON is 3D
// var imgLink = aData[4]; // where 4 is the zero-origin column for 2D
var imgTag = '<img src="' + imgLink + '"/>';
$('td:eq(4)', nRow).html(imgTag); // where 4 is the zero-origin visible column in the HTML
return nRow;
}
3) Similar to above, but instead of adding a whole tag, you just update a class that has the image as a background. You would do this for images that are repeated elements rather than one-off or unique pieces of data.
You mean an image inside a column of the table?
Yes, just place an html image tag
like this
<img src="Images/PictureName.png">
instead of putting data (some string) into a column just put the above html tag....
Asp.net core DataTables
The following code retrieve the image from a folder in WWWroot and the path in the DB field ImagePath
{
"data": "ImagePath",
"render": function (data) {
return '<img src="' + data + '" class="avatar" width="50" height="50"/>';
}
}
In case the Name of the picturefile is put together out of one or more informations in the table, like in my case:
src="/images/' + Nummer + Belegnummer + '.jpg"
you can make it that way:
var table = $('#Table').DataTable({
columnDefs: [
{
targets: 0,
render: getImg
}
]
});
function getImg(data, row, full) {
var Nummer = full[1];
var Belegnummer = full[4];
return '<img src="/images/' + Nummer + Belegnummer + '.jpg"/>';}
The picture is in the first column, so Targets = 0 and gets the Information from the same row.
It is necessary to add the parameters data and row.
It is not necessary to outsource it into a seperate function, here getImg, but it makes it easier to debug.
