[FEATURE] StatChart: configurable multi-series layout (auto/row/grid)

[colivi]

Relates to perses/perses#4382

Description

Multi-value StatCharts laid all series on one horizontal row (overflow scroll).

Maximizes space wrt number of elements to fill so panels that have multiple sub-panels to display stay readable.

• auto: pick columns from series count (4→2×2, 6→3×2, …)

• row: legacy horizontal strip

• grid: wrap; optional fixed seriesColumns (2, 3, …)

• Options editor: Series layout control

Screenshots

N/A until deployed on Argos; change is layout-only in "StatChartPanel.tsx".

Hi @shahrokni,

OK we’ll hold #814 in favor of #812 for the moment.

When orientation is auto, does the layout wrap into multiple rows based on panel width and the number of series (keeping each tile at least a minimum readable width)?

=> That’s the behavior we need for dense multi-series stats.

We’ll re-test Argos multi-series stats after merge and if gaps remain we will open a follow-up.
Thanks

You can take a look at this output.
The very first one (in the screenshot) shows your requirement I think. If not, let me know
