finding(plugin-charts): a sankey whose rows are all zero-or-negative renders a literally empty div — the one silent blank left on the chart surface after #7130 #7140

Description

@os-warren

Filed unassigned by the implementer of #7130 (PR #7139) while sweeping the chart-side empty-result population. ⛔ Out of scope there and deliberately not fixed in that PR — different defect class, different file.

The measurement

packages/plugin-charts/src/AdvancedChartImpl.tsx, the sankey arm:

const rows = data.filter((r) => (Number(r?.[dataKey]) || 0) > 0);
...
const links = rows.map(...);
if (links.length === 0) {
return <div className={className} />;
}

The filter keeps only strictly positive values. So a sankey handed real rows whose measure is all 0, all null, or negative produces no links and returns a bare div — no marks, no message, no role, no data-chart-error code. Nothing at all renders.

This is not the empty-result case #7130 covers. ObjectChart's new branch is gated on finalData.length === 0; here finalData.length is greater than zero — the query succeeded AND returned rows — so the empty state correctly does not fire, and this blank survives it.

Why it is worth recording now rather than later

Before #7130 this arm was one silent blank among several, so it did not stand out. After it, every other way an ObjectChart can come up empty explains itself — loading skeleton, chart-error alert box, chart-no-datasource, and now the chart-empty-state status box — and this is the last path that renders a blank tile and says nothing. The same reasoning the maintainer applied in hotcrm#1212 reads straight across: nothing on screen tells the reader whether the widget failed or is simply reporting a genuinely all-zero flow.

Note also that the two existing refusals in this file (hasNoCategoryKey, hasNoPlottableSeries) are both gated rows.length > 0 and render through the shared ChartRefusal shell with role="status" and a diagnosis code. That shell is the obvious seam for this case; it is right there in the same file, which is why the fix looks small. Whether the honest copy is "nothing to plot" or something naming the all-zero cause is a judgement this card does not pre-make.

⛔ What this card does NOT assert

It does not assert the blank is wrong. An all-zero flow may be a legitimate thing to draw as nothing, and the same restraint #7130 was filed under applies here: whoever takes it should render it and look at it first, and closing it measured-and-declined is a legitimate outcome.

              finding(plugin-charts): a sankey whose rows are all zero-or-negative renders a literally empty div — the one silent blank left on the chart surface after #7130 #7140

              Description

              @os-warren

              Filed unassigned by the implementer of #7130 (PR #7139) while sweeping the chart-side empty-result population. ⛔ Out of scope there and deliberately not fixed in that PR — different defect class, different file.

              The measurement

              packages/plugin-charts/src/AdvancedChartImpl.tsx, the sankey arm:

              const rows = data.filter((r) => (Number(r?.[dataKey]) || 0) > 0);
              ...
              const links = rows.map(...);
              if (links.length === 0) {
              return <div className={className} />;
              }
              

              The filter keeps only strictly positive values. So a sankey handed real rows whose measure is all 0, all null, or negative produces no links and returns a bare div — no marks, no message, no role, no data-chart-error code. Nothing at all renders.

              This is not the empty-result case #7130 covers. ObjectChart's new branch is gated on finalData.length === 0; here finalData.length is greater than zero — the query succeeded AND returned rows — so the empty state correctly does not fire, and this blank survives it.

              Why it is worth recording now rather than later

              Before #7130 this arm was one silent blank among several, so it did not stand out. After it, every other way an ObjectChart can come up empty explains itself — loading skeleton, chart-error alert box, chart-no-datasource, and now the chart-empty-state status box — and this is the last path that renders a blank tile and says nothing. The same reasoning the maintainer applied in hotcrm#1212 reads straight across: nothing on screen tells the reader whether the widget failed or is simply reporting a genuinely all-zero flow.

              Note also that the two existing refusals in this file (hasNoCategoryKey, hasNoPlottableSeries) are both gated rows.length > 0 and render through the shared ChartRefusal shell with role="status" and a diagnosis code. That shell is the obvious seam for this case; it is right there in the same file, which is why the fix looks small. Whether the honest copy is "nothing to plot" or something naming the all-zero cause is a judgement this card does not pre-make.

              ⛔ What this card does NOT assert

              It does not assert the blank is wrong. An all-zero flow may be a legitimate thing to draw as nothing, and the same restraint #7130 was filed under applies here: whoever takes it should render it and look at it first, and closing it measured-and-declined is a legitimate outcome.
