Hi George,
Thanks for using Syncfusion Products, We have analyzed your requirement and it can be achieved by storing the ChartAxisLabelsCollection while loading the chart and then restoring it after editing the axis labels as in below code snippet.
Code snippet[C#]:
Storing the text:
ChartAxisLabelsCollection lc=new ChartAxisLabelsCollection();
lc=xaxis.VisibleLabels;
Restoring the text:
xaxis.LabelsSource = lc;
We have also prepared a simple sample based on your requirement which you can download from the attachment.
Please let us know if you have any concerns.
Thanks,
Michael Prabhu.
