Multiple canvasjs charts in MVC partial views

[darrenst]

I need to show 6-7 charts located in different MVC partial views.

Each pair of charts is located on a separate partial view

At the moment “Only” the last view is being rendered. I am not much a javascript coder but suspect its the multiple Window.onload functions events that is causing the issue.

I changed one partial view to call the Document ready event which worked, however I need to show 2 more charts.

Can you suggest a method to overcome this limitation whilst keeping the chart html and js located withing the partial view.

many thanks

Darrenst,

Please check the container IDs. ID should be different for every container. We would need a sample code in order to properly understand the problem and resolve it.

Hi, yes the container Ids are unique.

The issue I suspect is because I am running multiple script tags each with Window.Onload.

It seems the last Window.onload block is taking prescidence

please advise.

@arbitus40,

Please take a look at Rendering Multiple Charts within a Page in ASP.NET MVC Samples. You can download ASP.NET MVC samples from download page.

First, dont include canvas.js script every time. Then, you need unique id for div
<div >>>> id=”chart” <<< style=”height: 300px; width: 100%;”></div>
I have created wrapped for canvas.js model by generating random guid from which I set my id to div and then I am using the same id in script to generate canvas.js chart.

},
subtitles: [{

}],
data: [{
type: “pie”,
startAngle: 180,
toolTipContent: “<b>{label}</b>: {y}%”,
showInLegend: “true”,
