@drtrilogy,

We observe that the date-time format you are using is not a valid one. Please refer this link for valid JavaScript date-time formats.

You can use valueFormatString to format values (date in your case) that appear on axis labels. Please take a look at this updated jsfiddle.

Vineet Deodhar,

Profile pics in CanvasJS site are linked from Gravatar. When a user doesn’t have Gravatar account or image, it will fallback to the default Gravatar image which is shown as your profile pic now.

Please create a profile in Gravatar and associate avatar images to your email-id, which you have used to sign-up in CanvasJS site. This will update the same in your CanvasJS profile.

@coolex,

You can set color and lineColor properties to all the dataPoints which are to be distinct. Please check this jsfiddle.

Also you can use stripLines on axisX to show the distinction.

@corylee766,

Since you are using getJSON, including jQuery library to the webpage will work fine in your case. Please download static html from here.

@nitin_nn,

For security reasons, browsers restrict cross-origin requests. JSONP allows you to sidestep the cross-origin requests. Please refer JSONP for more info.

You can also take a look at this jsFiddle for an example on JSONP.

You can use xValueFormatString to format x-values that appear on toolTip or indexLabels.

[UPDATE]

We have released React Component for Charts using which you can build charts in react way. Please refer to this blog post for release note.

@netcon,

Adding type=”text/babel” to the src attribute of script tag should work fine. Please refer this stackoverflow thread for more information.

If you are still facing issue, kindly create sample project reproducing the issue you are facing and share with us over Google-Drive or Onedrive so that we can run it locally to understand the scenario better and help you out.

Also please take a look at this JSFiddle for an example on rendering Column Chart using ReactJS.

Praveen,

We don’t have plugin architecture within the product as of now. However you can add custom DOM elements on top of chart and customize it the way you want. Please take a look at this jsfiddle. Also refer Position Image over Chart for tutorial on positioning DOM on chart.

@tdono,

You can render chart with data from html-table by reading entire column and by parsing it to the format accepted by CanvasJS.

Please take a look at this jsfiddle.

@praveen-garg,

Applying custom CSS to indexLabel is not available as of now, but you can customize toolTip either by using contentFormatter or by over-riding toolTip class as shown in this jsfiddle.

In bar/column charts, indexLabels are placed inside or outside based on the available space. You can set indexLabelPlacement in dataSeries level to outside so that indexLabels are shown outside the bar.

@dimas19801,

Please refer Tutorial on Creating Charts from JSON Data & AJAX.

The JSON data needs to parsed before passing it to chart-options. Check out the below code snippet for the same.

$.getJSON("https://api.npoint.io/6be170cb804361d314e3", function(chartData) {  
	for(var i = 0; i < chartData.length; i++){
  	dps.push({ x: new Date(chartData[i].x), y: chartData[i].y});
  }
	chart = new CanvasJS.Chart("wtChart", {    
  	title: {
    	text: "Chart from External JSON Data"
    },
    data: [
      {
        type: "column",
        dataPoints: dps
      }
    ]
  });
  chart.render();
});

Please check this JSFiddle for complete code.

@vidsocio,

Sorry for the inconvenience. We are looking into the issue. Meanwhile you can over-ride CSS as shown in this jsfiddle.

Tom,

A logarithmic axis can only plot positive values. There is no way to put negative values or zero on a logarithmic axis.

Fundamental: If 10L = Z, then L is the logarithm (base 10) of Z. If L is zero, then Z equals 1.0. If L is a less than 0, then Z is a positive fraction less than 1.0. If L is greater than 0, then Z is greater than 1.0. Note that there no value of L that results in a value of Z that is zero or negative. Logarithms are simply not defined for zero or negative numbers.
