Larry,

Its not possible to get dataSeries color using get method as of now.

However you can get the colorSet of the theme being used with the help of chart._selectedColorSet (which is an interval variable). Please take a look at this jsfiddle.

Larry,

You can set the dataPoint value to first dataPoint x-value of any other dataSeries. Please take a look at this updated jsfiddle.

@yansonalvin97,

You can update the chart data by changing options and calling chart.render();. Please refer to this documentation page for step-to-step tutorial on the same.

in your case, you need to group the datapoints from JSON based on year. Please take a look at this updated JSFiddle.

Also, we suggest you to initialize chart once before AJAX rather than initializing it on every AJAX calls.

Ryan,

Font size remains the same even after resize as you are setting indexLabelFontSize to 36. You can change indexLabelFontSize on resize of window and relate it to chart-container width and can have minimum and maximum limits on the same.

Kindly take a look at the code-snippet below,

$(window).resize(function() {
		
    for(var i = 0; i < chart.options.data.length; i++){
	chart.options.data[i].indexLabelFontSize = Math.min(36, Math.max( 12, $("#chartContainer").width() / 10));  
    }
    chart.render();
}); 

Please take a look at this updated jsfiddle.

@yansonalvin97,

One more question, is it possible to switch from multi series chart like stackedBar, stackedColumn graph to pie graph or doughnut graph?

Pie/Doughnut charts doesn’t support multi-series as of now. However switching between stackedBar/stackedColumn to pie/doughnut works fine where chart accepts and renders only first dataSeries.

The data of this graph comes from a json and I dont want to have a duplicate in the year. Can you please tell me whats going on? Thank you. This is my json

Can you kindly create jsfiddle with sample data, so that we can understand it better and help you out?

@kinokatsu,

The behavior is designed such that zooming is limited upto a certain region, so the user doesn’t end up zooming into a blank-region (region with no dataPoints). To zoom into a certain region, there should be a minimum of 3-4 dataPoints.

In your case, zoom doesn’t work as its getting invalidated over axisY. However zoomType: ‘x’ works fine in your case.

We will reconsider this behavior for future releases.

@yansonalvin97,

Please refer this documentation page for step-to-step tutorial on rendering chart with data from JSON. Adding another dataseries should let you create multi-series chart. Please find the code-snippet below.

$.getJSON("https://api.npoint.io/bad5c5a9b3669e0ff3ee", function(data) {
for(var i = 0; i < data.length; i++) {
    dps1.push({ label: data[i].label, y: data[i].y1 });
    dps2.push({ label: data[i].label, y: data[i].y2 });            
  }
});

Please take a look at this JSFiddle for complete code.

It’s possible to position image on top of chart with the help of convertValueToPixel method. Please take a look at this jsfiddle.

@yansonalvin97,

Incase of multi-series chart, you just need to update the type of every dataSeries. Please take a look at this updated jsfiddle.

@yansonalvin97,

Irrespective of data-source, CanvasJS supports dynamic updates of chart-options. So updating chart-type from dropdown should work fine even incase of json. Please take a look at this jsfiddle.

Sudhir,

Do you mean gradient as chart background? If so please take a look at this jsfiddle. However setting gradient as color is not available as of now.

If this doesn’t answer your requirements, can you kindly share pictorial representation of your requirement so that we can understand it better and help you out?

@kinokatsu,

Label is being clipped as you are restricting axis maximum. Setting labelAngle to a negative value should work fine in your case. Please take a look at this updated jsfiddle.
