In `@ui/app/workspace/dashboard/components/providerLatencyChart.tsx`:
- Around line 165-168: The bars currently set barSize={30} in
providerLatencyChart.tsx (the <Bar dataKey="avg_latency">, "p90_latency",
"p95_latency", "p99_latency") which forces a fixed width and conflicts with
Recharts' responsive grouping behavior; change these props to use
maxBarSize={30} instead of barSize so Recharts can auto-shrink grouped bars but
never exceed 30px, ensuring consistent dashboard sizing with other charts.

🧩 Analysis chain
🌐 Web query:
In Recharts 3.1.2, how does a fixed barSizebehave in groupedBarCharts when the total bar widths exceed the category width, and is maxBarSizesupported onBarorBarChart as a safer cap?
💡 Result:
Fixed barSize in grouped BarChart (Recharts 3.1.2) when bars “don’t fit”
In grouped bars, once Recharts detects that the group’s requested total width (sum of the per-series barSize plus barGaps) is >= the category band (bandSize), it does not let the bars overflow into neighboring categories:
- It first forces
barGapto0(removing inter-bar spacing) to try to make the group fit. - If the bars still don’t fit, it ignores the requested
barSizeand switches to an equal “full” size per bar (bandSize / numberOfBars), then multiplies that by 0.9 so the group fits with a little padding, and centers it within the band. [1]
So a fixed barSize is treated as a preference, but it will be shrunk (and gaps dropped) rather than overflowing when the group is too wide. [1]
Is maxBarSize supported, and is it a safe cap?
Yes—maxBarSize is supported on both:
<Bar maxBarSize={...} />[2]<BarChart maxBarSize={...} />[3]
But in 3.1.2 it is not a “cap” for an explicitly fixed barSize in grouped bars: maxBarSize is only applied in the branch where bar sizes are auto-computed (i.e., when barSize isn’t set / isn’t “well-behaved”). When you set a fixed barSize, the “doesn’t fit” fallback is the shrink-to-0.9 * (bandSize / n) behavior instead. [1]

Verify barSize consistency across dashboard components.
The barSize={30} change aligns with the existing dashboard design pattern (logsVolumeChart, tokenUsageChart, costChart, etc. all use barSize={30}). However, note that Recharts will automatically shrink grouped bars if they exceed the category band width—it won't clip or overflow. In single-provider mode with four bars per bucket, Recharts will reduce each bar below 30px and remove inter-bar gaps to fit within the available space. If 30px is a strict design requirement and auto-shrinking is undesirable, consider using maxBarSize as a constraint, though it only applies to auto-computed sizes, not explicitly fixed barSize values. The current implementation defers to Recharts' responsive sizing.

barSizefrom 8 to 30 pixels for all latency bars (avg, p90, p95, p99) in single provider modebarSizefrom 8 to 30 pixels for provider comparison bars in multi-provider modeType of change
Affected areas
How to test
Navigate to the workspace dashboard and verify that the provider latency chart displays with wider, more visible bars for both single provider and multi-provider views.
