100% Stacked Series

The 100% stacked series display the values from multiple series of the ASP.NET AJAX Chart as stacks or group of stacks over the x-axis categories, where the values proportions from each stack totals 100%. This series type is useful for cases where the contribution of values within stacks is more meaningful than the amounts themselves.

The functionality is available for category series - bar, column, line, area and radar (area, line and column).

Configure 100% Stacked Series

To configure 100% stacked series you should set the following properties of the first series - Stacked="true" and StackType="Stack100".

Figure 1: Shows the output from Example 1, which demonstrates stacked 100% column series.

You can create Figure 1 using the markup in Example 1.

Configure 100% Stacked and Grouped Series

To configure 100% stacked and grouped series, you should do the following:

1. Set the the following property to the first series - StackType="Stack100".

2. Set the same group name to the GroupName property of series that will be stacked in a separate group.

If you leave the GroupName property blank, all the series will be placed in one default stack. Setting the GroupName property of any series automatically sets the Stacked property of the first series to true, so it is not required to be explicitly set.

You can create Figure 2 using the markup in Example 2.
