--- Comment #19 from Tom <blackcat...@gmail.com> ---
Hi, this problem still exists in:
4.1.3.2 (freezes for ~32 seconds to resize the chart with anti-aliasing
enabled, ~17 seconds with anti-aliasing disabled)
4.3.0.4 (roughly same timing as above)

Any operation on the graph will result in a freeze for a considerable amount of
time, even opening and closing the 'Chart Type' dialogue without making any
changes results in a freeze.

Interestingly, after reducing the range to 3000 rows it takes around 3 seconds
to redraw the graph (and anti-aliasing doesn't seem to be making a big
difference here).

I have tested it using the test.ods file (11k+ rows, 2 columns).

By anti-aliasing I mean the settings as per "Options -> View -> Graphics output
-> Use anti-aliasing".

Also, it looks like the following reports are related to the same/similar
issue:
"Bug 79927 - LibreOffice Calc very slow to plot xy line graphic"
