Hello elinder,

I have reproduced this issue you are seeing, but it does not appear that the issue is being caused by the RefreshCompleted event handler. It appears to be caused by the end of the SearchHorizontalAxisCallback when you call the dependencyObject.RenderTransform = new TranslateTransform(0.0, -axisHeightAdjustment);

To prove this, consider removing the - from the -axisHeightAdjustment in your project. You will see the labels again, albeit they will be moved up quite a bit. This leads me to believe that what was happening is that the labels were being moved off of the screen, rather than being directly affected by the RefreshCompleted event handler.

I am unsure of what you mean by the Minimum and Maximum values not being bound correctly when the RefreshCompleted event is there though. When I run your sample project, it appears that those values are bound correctly. Could you please provide some more detail on the incorrect functionality you are seeing with the Numeric Y Axis' Maximum and Minimum value binding?

Please let me know if you have any other questions or concerns on this matter.

Hello elinder,

Regarding your first requirement to have the XAxis inside of the chart when YAxis values are below 0, there are two properties that you must set on the CategoryXAxis. These properties are CrossingAxis and CrossingValue. In this case, the CrossingAxis would be the Numeric Y Axis, and the CrossingValue would be 0. I also see that you have set the Numeric Y Axis' MinimumValue property to 0. You will want to remove this, or set it to something lower to get the negative values to show up in your chart.

Regarding your other requirements, I am unsure of the behavior you are seeing with the RefreshCompleted event being handled in your chart. Also, I am not entirely sure what you are asking regarding the ColumnSeries chart, as it appears that the Minimum and Maximum values are bound in the Numeric Y Axis correctly. Could you please provide some more detail on what requirements you are looking to fulfill with these points?

Please let me know if you have any other questions or concerns on this matter.
