Overview

All data is plotted as series, and each series consists of a related group of data points. This topic discusses some data requirements, and how those requirements relate to various chart types.

Data Points

Each data point consists of:

• An X value that determines where a data point is plotted (correlates to the DataPoint.XValue property).
• One or more Y values, which are the value(s) of the data points (correlates to the DataPoint.YValues array property). Some chart types require more than one Y value. For example, to plot one stock chart column four Y values are required: high, low, open, and close values denoted as Y, Y2, Y3, and Y4 values.

Note
When adding data points to a data series, you do not have to specify the X value since data is automatically plotted along the x-axis for you. (e.g. the X value for all data points in a series can be zero). When all X values are zero, data is plotted sequentially starting from zero.

 

All x-axis values for data points used in 3D charts must be sorted in ascending or descending order to avoid having an exception being thrown.

  

Data Series

The Series object's ChartType property determines how a series is drawn.

Note
For more information on chart types, refer to the topics in the "Chart Types" folder for a complete description of each chart type.

  

The following table summarizes the number of data series, and Y values required for each chart type:
