Hi,

I have a xamdatachart with  a columnseries. I set the color on my columns using the AssignCategoryStyle event in a behavior like this:

https://ko.infragistics.com/community/forums/f/ultimate-ui-for-wpf/122420/xamdatachart-columnseries-set-color-on-individual-column/539090

Now I want the color of the column to be updated when the color on my item is updated. The brush on my item notifies when it is changed and I have created a subscription for this that gets called:

 private void AssociatedObject_AssigningCategoryStyle(object sender, AssigningCategoryStyleEventArgs args)
{
if (args.GetItems(args.StartIndex, args.EndIndex)[0] is MyDataItem currentColumn)
{
this.brushSubscription = currentColumn.AsObservable(x => x.Brush)
.Subscribe(_ =>
{
args.Fill = currentColumn.Brush;
});
}

}

but the color on the column is not updated unless I resize my application window. How can I get the new color to show on my column?

Regards,

Hilma
