Priority: medium
Bug ID: 56505
Assignee: [email protected]
Summary: VIEWING: Scrolling complex chart is *very* sluggish
Severity: normal
Classification: Unclassified
OS: All
Reporter: [email protected]
Hardware: Other
Whiteboard: BSA
Status: UNCONFIRMED
Version: 3.6.1.2 release
Component: UI
Product: LibreOffice
Problem description:
A chart with a lot of data points will cause scrolling to take *very* long when
the chart is partially exposed. I seems like the chart is completely
recalculated, when it only needs to be calculated once then cached.
This is a general LibreOffice problem, not specific to Calc.
Steps to reproduce:
1. in Calc create a chart with 3,000 data points. The chart now sits between
rows 1 and 20
2. scroll down to row 25
3. scroll down to row 50
Current behavior:
Scrolling to row 25 takes very long (on my core i7). Scrolling to 50 is quick.
Expected behavior:
Scrolling should have no delay.
