Summary: Mask spreadsheet cell value does not recalculate
column statistics when bar chart contains error bars
Classification: Applications
Product: LabPlot2
Version First latest
Reported In:

Status: REPORTED
Severity: normal

Depends on: 525057
Target Milestone: ---
TL;DR
1) Mask spreadsheet value when displaying Average bar chart with error bars.
Result: AV chart shows old mean value.
Expected: Mean should be recalculated instantly.
========================================
1) Create spreadsheet and fill one column with example values:
1
2
3
4
2) In project explorer or on Spreadsheet area:
Right click → Columns Statistics Spreadsheet
3) From Statistics Spreadsheet plot column:
"ArithmeticMean {Double} [Y]" Right click → Plot Data → Bar Plots → Bar Plot
4) Set Error Bars:
e.g.:
"StandardDeviation {Double} [Y]"
5) Click on spreadsheet cell or select range:
Selection → Mask
e.g.
1
2
3
[4] <--- masked
Actual Result:
ArithmeticMean and bar chart indicate old average AV of {1,2,3,4} = 2.5.
Expected:
Values should be recalculated instantly and automatically whenever mask is
applied.
Resulting with:
AV of {1,2,3} = 2.0.
Additional info:
Removing mask recalculates statistics and plot correctly. But applying mask
does not recalculate related project entities.
