Caliper's history charts were drawing things nobody measured. This fixes that,
which is the whole of the release.
What changed
- A gap in the record now looks like a gap. A bucket is written only when
the Mac is awake to be measured, so a night's sleep leaves a hole — and the
chart used to join the two edges of it with a straight line and fill the
min/max band underneath. On this machine that turned sixteen hours of nothing
into a smooth ramp on the disk and network plots. The line now breaks where
the record breaks, and a stretch of one lone bucket is marked with a point
rather than vanishing. - The one-hour view shows its top processes again. It had been asking the
process log for the half-minute the cursor was standing in, which is usually
still being written; it now takes the newest half-minute that was, and says
which one it is showing. With recording switched off it goes back to showing
nothing, which is the point of the switch. - A chart stays inside its card. The temperature panel's shading was drawn
past the bottom of its card and over the readings underneath — it was filling
from zero, and that chart's scale starts near body temperature.
About the numbers
"Under 1 % of one core" is the steady state — menu bar up, nothing open. A
panel costs more while it is open, around 2 %, because it samples and draws
what it shows. Both figures are shares of one core, the unit Activity
Monitor's %CPU column uses, not of the whole machine.
Requirements
macOS 15 or later, Apple Silicon. Sensors are read on a best-effort basis: what
a particular Mac will not report is hidden rather than guessed at.
