The value axis printed "-1MB, -1MB, 0MB, 0MB, 1MB, 1MB" whenever the chart had no data: the formatter renders whole megabytes, MPAndroidChart picks the label interval from the data, and an all-zero chart gave it a range of about -1MB to 1MB with six labels, which round onto three strings each printed twice. Half of them were negative, which memory cannot be. axisMinimum removes the negative half. Granularity floors the interval at a megabyte, which is the smallest step the label text can tell apart. It is a floor rather than the interval itself, so a chart spanning hundreds of megabytes is unaffected -- it only bites in the degenerate case it exists for. The all-zero state is not rare: watchMemory calls resetMemUsageChart before any sample has been taken, so there is a flash of it at every editor open, and it persists while the editor is paused, which is how it was first seen -- behind the translucent "Install this app?" prompt, where the chart stays on screen with nothing updating it. The axis setup moves to MemoryChartAxis so the labels can be tested at all. What the library prints depends on the range it chooses, and that is only decided during a layout and a draw, so the test lays the chart out and draws it and reads the computed labels back. Both failing assertions were confirmed against the unfixed code, one of them reproducing the reported "-1MB" exactly. Note this is superseded on the metrics carousel branch, which replaces this chart: ADFA-5486 already clamps each page's axis to a range of at least 64MB, so no interval there can fall below a megabyte. Verified on a Pixel 6 Pro -- the carousel's all-zero axis reads 60/50/40/30/20/10/0MB. This fixes the chart that ships from stage until that lands.

The memory chart's value axis printed
-1MB, -1MB, 0MB, 0MB, 1MB, 1MBwhenever the chart had no data. The formatter renders whole megabytes, MPAndroidChart picks the label interval from the data, and an all-zero chart gave it a range of about -1MB to 1MB with six labels — which round onto three strings, each printed twice. Half of them were negative, which memory cannot be.The fix

Granularity is a floor rather than the interval itself, so a chart spanning hundreds of megabytes is unaffected — it only bites in the degenerate case it exists for.The state is not rare

To
MemoryChartAxis, so the labels can be tested at all. The bug was never in the formatter — it was in the interval the library chose to hand it, and that is only decided during a layout and a draw. So the test lays a real chart out, draws it, and reads the computed labels back.Four tests: an all-zero chart has no duplicate labels and no negative ones; a chart with real readings still labels distinctly (which is what would fail if the granularity floor ever started to bite); and the labels are whole megabytes. Both failing assertions were confirmed against the unfixed code, one reproducing the reported

:appunit suite andspotlessCheckgreen.This is superseded on the carousel branch
Worth knowing before reviewing: the metrics carousel replaces this chart entirely, and it does not have this bug. ADFA-5486 clamps each page's axis to a range of at least 64 MB, so no interval there can fall below a megabyte, and the network and power pages set
granularity = 1fexplicitly. Verified on a Pixel 6 Pro — the carousel's all-zero axis reads60/50/40/30/20/10/0MB, seven distinct labels.So this fixes the chart that ships from
stageuntil the carousel stack lands. It is deliberately offstagerather than on that stack, because on the stack there is nothing to fix. If a release is not expected before the carousel merges, closing ADFA-5535 as already-fixed-by-5486 is the reasonable alternative and I would not argue against it.Font scale
The axis carries fewer, wider-spaced labels than before in the degenerate case and the same number otherwise, so if anything this is easier to read at 2.0. No layout or text sizing changed. Verified at 1.0.
