XamData Chart Blanks on Refresh
posted

I have a XamDataChart that is periodically updated with new data.  I clear the chart of all series and re-add new series and when this happens, the chart will momentarily blank before it displays the new data - it seems like the act of clearing and re-adding series takes time and the visual display is trying to draw in the intermediate state.  Is there a way to prevent this from blanking until the entire chart is ready to be displayed?

    Hi Gary,

    How is the data updated?  Are new points being added/removed or is the entire collection being replaced?  In either case it would be better if you did not replace the entire series object.  If you are adding/removing items periodically then INotifyCollectionChanged notifications should be enough to update your series.  If you are replacing the entire collection then just assigning a new ItemsSource for the existing series is enough.  Replacing the series each time is not necessary as long as you just update the ItemsSource.
