Previously, perf-o-meter bars in Top list widgets rendered incorrectly when the metric value fell outside the configured data range. For example, setting a minimum of 40 with a maximum of 100 while the actual value was below 40 caused the bar to appear fully filled instead of empty.

The bar width is now clamped so that values below the minimum show an empty bar and values above the maximum show a full bar.
