Description Erich E. Hoover 2022-02-08 16:59:22 UTC

Description:
When you hover over a data point in the chart it is supposed to display the value of the data point in a "hover tip".  This feature appears to be broken in the gtk3 VCL UI, as no "hover tip" is displayed.  It appears that people have been experiencing this issue for a while, but nobody has reported a bug:
https://ask.libreoffice.org/t/graph-point-value-when-mouse-hover/53155/12

Steps to Reproduce:
1. Launch libreoffice with the GTK3 backend (SAL_USE_VCLPLUGIN=gtk3 libreoffice)
2. Create a chart with data points
3. Double click to edit the chart (or choose Edit -> Object -> Edit from the menu)
4. Hover your mouse over a data point

Actual Results:
No "hover tip" is displayed.

Expected Results:
A "hover tip" giving the values of the data points should appear


Reproducible: Always


User Profile Reset: No


OpenGL enabled: Yes

Additional Info:
Please note that the gtk3 VCL UI is the default for many Linux systems (such as Debain/Ubuntu).  If you launch with the generic VCL UI (SAL_USE_VCLPLUGIN=gen libreoffice) on such a system then you can see the expected behavior.

Comment 2 Caolán McNamara 2022-02-23 15:00:09 UTC

what is sometimes the case for tooltips is that there is no "area" given for the tooltip, only a point, and gtk won't show a tooltip for an empty area
