ActualInterval is not updated for NumericYAxis
posted

Hi,

I am facing a problem with XamDataChart (NumericXAxis and NumericYAxis). Data is dynamic loaded but XamDataChart  is placed in a non-selected TabPage. Moreover, NumericYAxis maximum and minimum are set (code behind) depending on the loaded data range. 

If XamDataChart is visible, visually NumericYAxis has a correct interval, but in code behind, ActualInterval [https://ko.infragistics.com/help/wpf/infragisticswpf.controls.charts.xamdatachart~infragistics.controls.charts.categoryxaxis~actualinterval] is not updated; it belongs to the previously loaded data.

The following are a summary of my chart settings:

  • Horizontal/Vertical Zoom is Enabled
  • Y Axis Label Settings Location is "OutsideLeft"
  • Chart Series Clear() is called each time a new data is loaded

Any idea how to enforce updating ActualInterval property? 

I am using  Infragistics WPF UItimate   (version 18.1.20181.176).

    Hello, 

    Thank you for contacting Infragistics. From my understanding you wish to update the axis range. This will only occur after removing a series. 

    There are a few things you can do here to remove a specific series. If you know your series, or the index of it, I would recommend using the Remove or RemoveAt methods of the XamDataChart.Series collection, like so:
    Chart.Series.Remove(mySeries);
    Chart.Series.RemoveAt(0);
    This will cause the chart to refresh itself. Let me know if you have any questions.
