Description Rainer Bielefeld 2009-01-04 15:33:11 UTC

This report is a spin off from Issue 97722. Pls. use sample documents from Issue
97722 to reproduce the problem and read introduction there.

Steps to reproduce:
0. open WIN Task Manager so that you can see processor load
1. Open "Problems.ods" with sheet "Diagramm1"
2. doubleclick white chart area below legend to open "chart mode"
   It seems that redraw action takes much time (20 seconds).
3. Right click / Context menu "Data Ranges"
   Modify from "$Auswertung1.$A$1:$N$1600" in Data Range pane to 
   "$Auswertung1.$A$1:$N$1599" and press <ok>
   Expected: Chart should be redrawn within few seconds
   Actual: Takes more than 30 seconds

11. No open "Bigproblems.ods" with sheet "Diagramm1" and redo from "2."  
    - hope you don't need OOo for anything else next week ;-)

This might be related to (or even a DUP of) Issue 97722

@aw, this is a symbol chart with 8 * 1600 symbol shapes. The creation of those
shapes is what takes very long in this case. I think for this example your idea
of a meta-sdr-object could help a lot to reduce the amount of created shapes -
having 8 shapes only (with 1600 transformations each) instead of 12 8000 shapes.
Maybe we can take this issue as the feature task for the meta-sdr-objects. I
changed the summary accordingly.

AW: Did some checks. There is still some broadcasting in
SdrObjList::InsertObject and SdrObjList::RemoveObject which can be avoided when
model is locked; but the main part is object creation, property setting
(SfxItemSet copy constructor) and similar. A basic solution would indeed need a
meta-object. Thinking about possible concepts, but removing from AW075 for the
moment...
