kChartPopoverValueFontSize top-level constant

double const kChartPopoverValueFontSize

Font size of the single-value Y reading. ChartPopover.tsx:86.

fontSizeHero700 is 28px. The inline style beats calloutContentY's own class, which would otherwise be subtitle2Stronger for a cartesian chart or title2 for a non-cartesian one (useChartPopoverStyles.styles.ts:79-84). The multi-value path does not set it (ChartPopover.tsx:229).

Implementation

const double kChartPopoverValueFontSize = 28;
