I am trying to run a sketch on the canvas element in Nuxt JS but I am having some issues (I am completely new to Vue JS).
While I have no errors in VS Code, there is an error in the browser console:

Any ideas on the why lines 29 and 127 of the Blob_Point.js file are throwing errors?
I attached 2 screens of the developer tools in chrome to show the errors along with the JS its pointing to.
Thanks for any help!
The main issue I can identify is here. I have added comments to the code.
Blob_Point.js
render() {
let canvas = this.canvas // this references the Blob Class (not the Vue instance) and there is no initialised property such as canvas in the class
}
To fix this main issue, you can do something like
Blob_Point.js
export default class Blob {
constructor(color, canvas) {
//the objects setup
// 'this' is a reference to the current class
this.points = []
this._color = color;
this.canvas = canvas
}
}
And then in the .vue file
.Vue
mounted() {
let canvas = document.getElementById("myCanvas");
this.canvas = canvas.getContext("2d");
blob = new Blob("#C09EFF", this.canvas); // now canvas in the Blob Class constructor will refer to the vue instance canvas
blob.canvas = canvas;
blob.init();
blob.render();
},
I have identified another issue here.
set canvas(value) {
if (
value instanceof HTMLElement &&
value.tagName.toLowerCase() === "canvas"
) {
this._canvas = canvas // there is no initialised constructor property as _canvas
this.ctx = this._canvas.getContext("2d") // there is no initialised constructor property such as _canvas
}
}
get canvas() {
return this._canvas // there is no initialised constructor property as _canvas
}
Trying to apply the following: https://bl.ocks.org/mbostock/4015254, on to my dataset. I have changed the variables to fit my dataset.
My code is the following:
<script>
var svg = d3.select("svg"),

g = svg.append("g").attr("transform", "translate(" + margin.left + "," + margin.top + ")");
var parseDate = d3.timeParse("%Y-%m-%d"),
formatDate = d3.timeFormat("%Y");
var x = d3.scaleTime()
.domain([new Date(2002, 0, 1), new Date(2003, 0, 1)])
.range([0, width]);
var y = d3.scaleLinear()
.range([height, 0]);
var xAxis = d3.axisBottom(x);
var yAxis = d3.axisLeft(y);
var area = d3.area()
.curve(d3.curveStepAfter)
.y0(y(0))
.y1(function(d) { return y(d.value); });
var areaPath = g.append("path")
.attr("clip-path", "url(#clip)")
.attr("fill", "steelblue");
var yGroup = g.append("g");
var xGroup = g.append("g")
.attr("transform", "translate(0," + height + ")");
var zoom = d3.zoom()
.scaleExtent([1 / 4, 8])
.translateExtent([[-width, -Infinity], [2 * width, Infinity]])
.on("zoom", zoomed);
var zoomRect = svg.append("rect")
.attr("width", width)
.attr("height", height)
.attr("fill", "none")
.attr("pointer-events", "all")
.call(zoom);
g.append("clipPath")
.attr("id", "clip")
.append("rect")
.attr("width", width)
.attr("height", height);
d3.json("api.php", function(d) {

d.value = +d.close;
return d;
}, function(error, data) {
if (error) throw error;
var xExtent = d3.extent(data, function(d) { return d.date; });
zoom.translateExtent([[x(xExtent[0]), -Infinity], [x(xExtent[1]), Infinity]])
y.domain([0, d3.max(data, function(d) { return d.value; })]);
yGroup.call(yAxis).select(".domain").remove();
areaPath.datum(data);
zoomRect.call(zoom.transform, d3.zoomIdentity);
});
function zoomed() {
var xz = d3.event.transform.rescaleX(x);
xGroup.call(xAxis.scale(xz));
areaPath.attr("d", area.x(function(d) { return xz(d.date); }));
}

It consists of 2831 records. I don't understand why even my x and y axes aren't printing correctly. Thanks in advance.
The bl.ocks that you refer to uses a d3.csv which (if you look at the docs) has an accessor function that is passed each row of the data and then the whole date is accessed in the callback. Here's the accessor function:
function(d) {
d.date = parseDate(d.date);
d.value = +d.value;
return d;
}
But in case of d3.json, there's no such accessor: d3.json(url[, callback]) which means you'll have to parse each row within the callback. Here's how:
d3.json("test.json", function(data) {
data.forEach(e => {
e.date = parseDate(e.date);
e.value = +e.close;
});
var xExtent = d3.extent(data, function(d) { return d.date; });
.....
Here's a fork of your code (I'm not sure why you have the file named as "api.php" when it is a JSON file. I've used a "test.json" file.
https://bl.ocks.org/shashank2104/21358032ac5507f7a6b7d620b1a4ef69/12b6089547e3b07edeca6214834d7e7a340be6a7

Hope this makes sense. Also, I'm setting the x domain to the xExtent that is computed from the data. Play around with it to see the difference.
Somehow the load function is of a different type and uses the following format.
d3.json("api.php", function(data) {
data.forEach(e => {
e.date = parseDate(e.date);
e.value = +e.close;
});
var xExtent = d3.extent(data, function(d) { return d.date; });
zoom.translateExtent([[x(xExtent[0]), -Infinity], [x(xExtent[1]), Infinity]])
y.domain([0, d3.max(data, function(d) { return d.value; })]);
yGroup.call(yAxis).select(".domain").remove();
areaPath.datum(data);
zoomRect.call(zoom.transform, d3.zoomIdentity);
});
PDF export for custom widget doesn't work from icCube reporting. Server engine version is 5.0.3 and reporting 5.0.3 (6:2163).
We didn't see any error message within the logs, the process remains stuck into the Monitoring -> Active Requests tab.
The report included is based on icCube demo Sales schema.

Widget adapter code needs two extra functions(workaround for internal bug):
FishboneChartAdapter.prototype.hasNavigation = function()
{
return false;
};
FishboneChartAdapter.prototype.getNavigationMenuItems = function()
{
return [];
};
isRendered method should be modified, because layout for chart computed dynamicaly. I suggest to use simple setTimeout to with heuristic timeout, but you may implement custom check.
FishboneChart:
test.module.FishboneChart = (function (_super) {
__extends(FishboneChart, _super);
function FishboneChart(container, options) {
_super.call(this, container, options);
this.options = options;
this.container = container;
this.rendered = false;
var chartContainer = $("<div class='ic3w-fishbone-chart'></div>");
var contentContainer = $("<div class='ic3w-fishbone-chart-content'></div>");
var ct = $(this.container);
ct.append(chartContainer);
chartContainer.append(contentContainer);
};
$.extend(FishboneChart.prototype, {
buildInHtml: function (gviTable) {
var chartData = buildChartDataJson(gviTable);
renderFishboneChart(chartData);
var self = this;
// wait until layout is stabilized
setTimeout(function(){self.rendered = true;}, 10000);
},
isRendered: function () {
return this.rendered;
}
});
return FishboneChart;
})(viz.GviChartBase);
I have written a backbone view which takes a file object or blob as an option in instantiation and then checks that file for EXIF data, corrects orientation and resizes the image if necessary depending on the options passed in.
Within the view there is a function mainFn which takes the file object and calls all other subsequent functions.
My issue is how to I test mainFn that uses ReadFile and an image constructor?
For my test set-up I am using mocah, chai, sinon and phantomjs.
In my sample code I have removed all other functions as to not add unnecessary clutter. If you wish to see the whole view visit its github repository.
var imageUpLoad = Backbone.View.extend({
template: _.template(document.getElementById("file-uploader-template").innerHTML),
// global variables passed in through options - required
_file: null, // our target file
cb: null,
maxFileSize: null, // megabytes
maxHeight: null, // pixels - resize target
maxWidth: null, // pixels - resize target
minWidth: null, // pixels
maxAllowedHeight: null, //pixels
maxAllowedWidth: null, // pixels
// globals determined through function
sourceWidth: null,
sourceHeight: null,
initialize: function (options) {
this._file = options.file;
this.cb = options.cb;
this.maxHeight = options.maxHeight;
this.maxWidth = options.maxWidth;
this.maxFileSize = options.maxFileSize;
this.minWidth = options.minWidth;
this.maxAllowedHeight = options.maxAllowedHeight;
this.maxAllowedWidth = options.maxAllowedWidth;
},
render: function () {
this.setElement(this.template());
this.mainFn(this._file);
return this;
},
// returns the width and height of the source file and calls the transform function
mainFn: function (file) {
var fr = new FileReader();
var that = this;
fr.onloadend = function () {
var _img = new Image();
// image width and height can only be determined once the image has loaded
_img.onload = function () {
that.sourceWidth = _img.width;
that.sourceHeight = _img.height;
that.transformImg(file);
};
_img.src = fr.result;
};
fr.readAsDataURL(file);
}
});

You could either mock the FileReader / Image on the window, e.g.
// beforeEach
var _FileReader = window.FileReader;
window.FileReader = sinon.stub().return('whatever');
// afterEach
window.FileReader = _FileReader;
Or reference the constructor on the instance, e.g.
// view.js
var View = Backbone.View.extend({
FileReader: window.FileReader,
mainFn: function() {
var fileReader = new this.FileReader();
}
});
// view.spec.js
sinon.stub(this.view, 'FileReader').return('whatever');
Personally I'd prefer the latter as there's no risk of breaking the global reference if, for example, you forget to reassign the original value.
i am new to programming.. i have this code which gives distance between two points but need to further multiply it by an integer say 10.. the project i am working on is abt calculating distance between two points and multiplying it with fare/Km like Rs.10/km (Indian Rupees) for the same. So if the distance is 30 km the fare would be 30*10 = Rs.300
Thanks in advance

I use an Ajax call to PHP, and haven't yet used getDistanceMatrix(), but this should be an easy fix.
First, if you know you will always only have one origin and one destination, you don't need the "for" loop in your callback function. Second, you're taking the distance text rather than the distance value.
function callback(response, status) {
if (status != google.maps.DistanceMatrixStatus.OK) {
[...]
} else {
deleteOverlays();
var outputDiv = document.getElementById('outputDiv'),
origin = response.originAddresses[0],
destination = response.destinationAddresses[0],
result = response.rows[0].elements[0],
distance = result.distance.value,
text = result.distance.text,
price = 10 * distance;
outputDiv.innerHTML = '<p>' + text + ': Rs.' + price + '</p>';
addMarker(origin, false);
addMarker(destination, false);
}
}
I haven't tested this, so it probably needs to be tweaked. ( See https://developers.google.com/maps/documentation/distancematrix/#DistanceMatrixResponses )
