Here is an example for adding Interactive Bar Charts into your ASP.NET MVC Application using CanvasJS. Like in Column Charts, Bar Charts can also have one or more Data Series. In case of more than one series, Data Points from different Series are placed next to one another and are differentiated by their color.
Please refer to this tutorial for step by step instruction of adding charts to your ASP.Net MVC Application. We recommend that you download the Sample Visual Studio Project and try it on your own to understand the API better.
var chart = new CanvasJS.Chart("chartContainer", {
.
.
data: [{
type: "bar",
dataPoints: [
{ y: 6, label: "Apple" },
{ y: 4, label: "Mango" },
{ y: 5, label: "Orange" },
]
}]
.
.
}
You can further customize these charts to enable features like Zooming, Panning, Exporting, etc. To know more about the available features, please refer to our getting started section.
