Hello Steve,

I'm having difficultly picturing your visual data. Please provide a mockup/screenshot of the desired behavior and post in this thread. You will most likely need to use the SeriesCreated event on the StackedColumnSeries since you are autogenerating the fragment series dynamically.  The generated StackedFragmentSeries will be passed as the sender to the event so you can set whatever properties you need to on this object, including the brush it uses.

Let me know if you have any additional quesitons regarding this matter.

Thanks for the response, could you potentially supply an example of the SeriesCreated handler please? As that does sound like the way to do this.

Thanks in advance.

See below as an example for what I'm trying to do but this is all one bar hence the stackedbar series. It keeps going and can be any of the 3 states at any time.

Sorry, see attached screenshot.

Hello Steve,

Thank you very much for following up. I've attached a sample that demonstrates how to style each fragment series based on a unique property defined. The Gap property on the CategoryXAxis will also eliminates the space between the left and right of each series.

Please review my sample, linked below, and let me know if you have any questions.

Thanks for the reply.

I've looked at your example and I can see what you've done however I'm implementing MVVM and my collection is an observable collection within a view model. I also have an add button which takes the user to a separate screen to enter the data to then be added to the collection. Obviously I want this graph to be automatically updated.

Any advice on how to implement this?

Regards.
