Fixes: 38877

Thank you for the changes! I still have 2 proposals:

• Percentages now default to one decimal place (100.0%), could the default be without it (100%)?
• When the chart was clickable, the mouse pointer used to change. Could it be added again?

What do you think?

Thank you, now it just needs to be verified

Note: getChartConfig should be removed in the future when AreaChart, BarChart, Chart, and LineChart get migrated to PF5.

FailedQA with foreman-3.18.0-0.20251218213508434273.pr10788.8925.g4e39e2f8a.el9.noarch on Firefox 146.0 build 20251211125526 and Chromium 143.0.7499.169.

1. Minor issue: just an unexpected change that is OK if confirmed to be intentional. Previously, when hovering over some pie chart part, the other parts were greyed out. Now they don't get greyed out so nothing highlights the part hovered over.

2. Hovering over a part shows a tooltip immediately and then after half a second, it shows a second - and incorrect - tooltip.

3. Inconsistency between percentage decimal places in different places: in Dashboard, it's 0 decimal places and in REX results old UI, it's 1 decimal place.
   Then in new UI it becomes "1/2 systems" for overall and "1 hosts" for part but that's OK.
   The inconsistency between the first two is something I consider a very minor bug, even more minor because old UI is being deprecated.

Also note that REX new UI has already been using PF5 version.
