Bug ID: 154165
Summary: Mean Value Line in wrong place when using Logarithmic
scale
Product: LibreOffice
Version: 7.4.6.2 release
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: minor
Priority: medium
Component: Chart
Assignee: [email protected]
Reporter: [email protected]
Description:
When inserting a Mean Value Line while a series of data is plotted using a Y
axis in Logarithmic scale, the mean value line does not use that scale but
linear scale instead. Hence the plotting of the Mean value does not correspond
to the values.
Steps to Reproduce:
1. Create a series of numbers (let be 1, 5, 10) in column
2. Select this column then click on the 'insert chart' button
3. Configure a Line chart with 'Lines Only' (doesn't really matter but for
visual purpose) and Finish the Chart creation
4. In the chart editor, select the created data series, then from the 'Insert'
menu, insert a 'Mean Value Lines'
5. Still in chart editor, edit Y axis, in the Scale tab with Logarithmic scale
and maximum value equal 1E+(expected mean value) (let be max=1e+6 for the
values of 1.)
Actual Results:
The values are plotted the right way, following the log scale (no problem
here).
The corresponding Mean Value Line is way higher, 'at the position it would be
in linear scale', for our values at 1e+(5.33)
Expected Results:
I would expect the Mean value Line to be 'around' the original values.
I don't know if I'm missing the setting to make it work properly but there
doesn't seem to be a way to specify the Y axis of the 'Mean Value Line' as the
Mean seems to follow the Y-axis setting of the 'original values'
Reproducible: Always
