Bug ID: 487748
Summary: LabPlot crashes when importing data to a spreadsheet
with an XY-Curve related to it and the column names
get changed
Classification: Applications
Product: LabPlot2
Version: 2.10.0
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: general
Assignee: alexander.se...@web.de
Reporter: 1293660...@qq.com
Target Milestone: ---
SUMMARY
When attempting to import data to a spreadsheet which has an XY-Curve related
to it, and the column names get changed due to the selection of "Replace" for
"Position" when importing, LabPlot will crash when the mouse cursor is moved to
the Plot Area. Sorry for the complicated summary; see "STEPS TO REPRODUCE"
below for a concrete example. You'll need a basic CSV file such as:
# test.csv
a,b
1,1
2,2
3,3
STEPS TO REPRODUCE
1. Prepare a "test.csv" file as described above
2. Open LabPlot and add a new spreadsheet
3. Right-click on the spreadsheet in the Project Explorer, "Import Data → From
File...", select the prepared file, ensure that "Position" is set to "Replace",
and click "OK"
4. Right-click on the spreadsheet in the Project Explorer, "Plot Data →
xy-Curve", select "New Plot Area in a new Worksheet", and click "Plot"
5. Change the column names of BOTH x-column and y-column, say from "a" to "c"
and from "b" to "d"
6. Re-import the same file (Step 3), so that the column names are set back to
"a" and "b"
7. Move the mouse cursor to the Plot Area
OBSERVED RESULT
LabPlot crashes
EXPECTED RESULT
LabPlot should not crash
SOFTWARE/OS VERSIONS
Linux: 6.9.2-arch1-1
KDE Plasma Version: 6.0.5
KDE Frameworks Version: 6.2.0/5.116.0
Qt Version: 6.7.1/5.15.13
ADDITIONAL INFORMATION
Only when the column names of BOTH x-column and y-column are changed will
LabPlot crash. Changing only one of them will not trigger the crash.
