An axis range defined by the user is now kept when a summary case or ensemble is added, reloaded or replaced. The range is marked as user defined when the user edits the min/max values, unchecks "Set Range Automatically" or zooms interactively in the plot.
The user defined range is released by "Zoom All", by double click in a plot, by checking "Set Range Automatically" or by changing the Y axis range aggregation of a summary multi plot.
