We changed what happens under the hood. High-cardinality line, bar, and pie charts now paint their data as a single lightweight layer instead of thousands of individual shapes, so hovering and updating stay responsive even at very high series counts. Initial load times are also improved.
We also made scrolling lighter in Logs, Traces, and the Web Events Explorer, so paging through thousands of rows keeps up with you (especially in Safari).
The result is the same Dash0 you know, just smoother where it used to strain. Dense dashboards feel snappy, hovering across a crowded chart no longer stutters, and scrolling thousands of rows in Logs, Traces, and the Web Events Explorer stays fluid.
We also fixed a related pie chart issue: a chart with many empty or zero value series could render blank. Those empty series are now skipped, so your real data always shows.
We will continue to improve the performance of some more charts in the upcoming months.
