XamDataChart

2035

Arthur Butler posted over 9 years ago

I have a StackedBarSeries XamDataChart where I update the data every 30 seconds. The data update via bindings does properly get reflected in the chart. However, when I update the Brushes property of the XamDataChart via bindings, the colors used in the chart are not updated. If I force a redraw by resizing the screen, then the colors are updated. What can I do to force the colors to be updated on the screen when the Brushes property is updated? Is this a bug?

Regards,

Arthur

Thanks for the quick reply. My datasource is a GroupBy. I was using a Key the same as the axis label. Once I set the key to match the index of the color then the problems went away.

I have a different issue with the markers showing twice, but I'll create a different post for that issue.

Regards,

Arthur

As long as the property you're binding to implements INotifyPropertyChanged or is a Dependency Property, it should work. I tested this out using the attached sample application, and it seemed to be working okay. Does this work on your end? Is this basically the same approach you were taking to change the brushes?
