Multiple series from the same major category are compatible with each other and can be combined in a single plot area. For example, a BarSeries and a LineSeries can be combined together in a YPlotArea.
For details on the API, see the YPlotArea class.
The following classes are used to create the bar and line series example:
Using Code
- Use the BarSeries and LineSeries classes to add data to the Chart control.
- Use the YPlotArea class to create the plot area.
- Set the location and size of the plot area.
- Add both series to the plot area.
- Create a label for the chart.
- Create a chart model and add the plot area and label to the model.
- Create a chart and add the chart model to it.
- Add the chart to the Spread control.
Example
The following example demonstrates using unbound data to create a chart that uses a bar series and a line series.
