What it does

  • Arranges plots in nested splits and tabs, with linked scales and cursors, so the layout need not be a strict grid.
  • Subscribes to live topics or imports .mcap and .db3 bags, and can overlay two or three recordings aligned by start time or by threshold.
  • Shows a curve-values sidebar, data statistics, and markers A and B that report time differences and slopes between curves.
  • Plots whole array fields against index or another array, and diagnostic messages from /diagnostics.
  • Plots topic rate, bandwidth and delay metrics, and applies filter chains such as derivative, integral, moving average and low-pass to curves.
  • Exports plots as PNG, SVG or PDF, and data as TXT or CSV; layouts are saved and loaded as XML.
