Property Value

Type	Description
BootstrapChartArgumentAxis	A BootstrapChartArgumentAxis object containing options related to the Chart’s argument axis.

Remarks

The rectangular coordinate system is used to determine each point uniquely on a plane through two numbers, the argument and the value of the point. Two perpendicular lines (the axis of arguments and the axis of values) are specified to define the coordinates. To define the argument axis, use the ArgumentAxis property. To define value axes, use the BootstrapChart.ValueAxisCollection property. When series are displayed on several panes, there should be a value axis for each pane defined. In addition, different series can be displayed using different value axes on one pane.

The BootstrapChart.SettingsCommonAxis property allows you to set the properties of all axes to a common value. Note that the value specified for an axis individually (through the ArgumentAxis or BootstrapChart.ValueAxisCollection property) overrides the value specified through the BootstrapChart.SettingsCommonAxis property.

Example

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.
