Details:

This are 3 patches to fix bug #44012 - GRAPH SCATTERPLOT crashes gui and one
minor issue regarding the title of the plots. 

https://savannah.gnu.org/bugs/?44012

As John already noted, the problem is that data is used during chart drawing
which is not valid anymore when the chart is drawn. I followed the strategy
used in npplot now also for scatterplot, i.e. a new case reader is created and
finally destroyed in the chart.

The patches are

1 - Comments from John regarding formatting of the code
2 - The actual fix of bug #44012
3 - A fix regarding x vs. y or y vs. x title see:
