Description Luke Hutchison 2004-01-21 04:18:24 UTC

When creating a graph, in preview mode, if you select a range of values for
the labels that is shorter than the range that defines the data series, the
following backtrace can result.  I guess if the Label series is too short,
the extra labels should be blank.

Comment 1 Jody Goldberg 2004-01-26 15:51:36 UTC

I can not replicate this.  It does highlight a problem where we draw
axis ticks based on the number of labels rather than data points. 
However it does not crash.

What version are you using ?  There was a problem with labels in early
1.2.x

Comment 2 Luke Hutchison 2004-01-26 18:11:08 UTC

v1.2.2.  Was it fixed before then, or should I upgrade and try again?

Comment 3 Jody Goldberg 2004-01-27 15:20:11 UTC

Hard to say.  Please try again with 1.2.5

Comment 4 Luke Hutchison 2004-01-27 23:40:31 UTC

Hmm, couldn't replicate it in 1.2.5, but it is possibly because a new
problem has surfaced: in 1.2.2, whenever you select another Label
range, within a second or two the preview in the Graph Properties
window updates to show the new Label range.

In 1.2.5, the axis labels are only ever updated automatically once;
the second time you select a range while the cursor is in the Label
field, even without clicking OK/Close, no update occurs.  If you
accept the new Label range, i.e. click OK, then the graph in the main
sheet is not updated with the new range either.  The only way to
update the range is right-click->Properties->OK.

Once this is fixed (in v. >1.2.5), I will try to get the label range
crash again -- as it is, I can't replicate it in 1.2.5, but then again
it sometimes required the selection of a few different ranges in 1.2.2
before it would crash, and only one range is selectable in 1.2.5
before it stops updating both the preview and the actual graph in the
sheet.

Comment 6 Jody Goldberg 2004-02-02 05:23:11 UTC

Things update correctly in both trees now.  Still no crash.
