Remarks

The Bootstrap Chart control visualizes data from a local or remote storage in a 2d coordinate system along with different interactive elements, such as tooltips, crosshair pointer, legend, etc.

To create a Bootstrap Chart control from your code, use the following API:

• BootstrapWebClientUIWidget.DataSource - binds a chart to the required date source.
• BootstrapChart.SeriesCollection - adds required series to a chart's series collection.
• BootstrapChart.ArgumentAxis, BootstrapChart.ValueAxisCollection - sets up chart axes.
• BootstrapChartBase.SettingsLegend - provides options for setting up a chart legend.

Examples

This example demonstrates the basic functionality of the Chart control.

• Initilize a new instance of the BootstrapChart class.
• Bind the chart control to the required data storage. For this purpose, assign the URL of your data storage (in this demo, a JSON file) to the BootstrapWebClientUIWidget.DataSourceUrl property.
• Define chart axes. For this purpose, use the BootstrapChartArgumentAxis and BootstrapChartValueAxis classes.
• Add required series to the BootstrapChart.SeriesCollection array.
• Use other available BootstrapChart class properties to customize the chart. For instance, you can swap chart axes by setting the BootstrapChart.Rotated property to true.

The image below shows the result:

<dx:BootstrapChart runat="server" DataSourceUrl="~/jsondata/simple.json" TitleText="Daily Sales" Rotated="true">
    <ArgumentAxis ArgumentType="System.DateTime" MaxValue="2017-01-10" />
    <ValueAxisCollection>
        <dx:BootstrapChartValueAxis TickInterval="1" />
    </ValueAxisCollection>
    <SeriesCollection>
        <dx:BootstrapChartBarSeries ArgumentField="date" ValueField="sales" />
    </SeriesCollection>
    <SettingsLegend Visible="false" />
</dx:BootstrapChart>
