    Description

      Changes to the underlying data after the series, for example due to a model reset, will make the application hang. Changing the mapped column trigger the exact same effect.

      Example:

      diff --git a/examples/charts/chartsgallery/modeldatawidget.cpp b/examples/charts/chartsgallery/modeldatawidget.cpp
index 87a35fb8..c393e683 100644
--- a/examples/charts/chartsgallery/modeldatawidget.cpp
+++ b/examples/charts/chartsgallery/modeldatawidget.cpp

     mapper->setModel(model);
