For the second release this week, FSharpChart now supports binding for Stacked Charts. As always, one can download the latest release from:

In previous versions of FSharpChart it was not very intuitive how a Stacked Chart could be plotted. What one had to do was define a CombinedChart where one defines the charts to be combined with the same StackedGroupName property value:

This displays the following chart:

(Thanks to Tomas Petricek for this sample)

This approach also allows one to easily combine multiple Stacked Charts using different StackedGroupName properties:

This displays the following chart:

However, for Stacked Charts, a more intuitive approach would be just to specify a list of data series. With this new release one can now specify the data series using the following formats:

This now allows one to define, say a StackedColumn chart, using the much simpler expression:

This displays the following chart:

Hopefully you will agree this is much simpler and more intuitive. The only current limitation of this binding approach is that one cannot use a CombinedChart for multiple Stacked Charts when binding in this fashion. If this is the desire then the previous approach with distinct StackedGroupName properties is needed.

The download also includes a new WinForms sample demonstrating how bindings can be managed for these Stacked Charts.

Don’t forget, the previous release also added the ability to add a Marker for a Data Series:

Again, the this displays the chart:

Once again enjoy!
