QCustomMiniBarChart
A compact, axis-less bar chart.
The painted sibling of QCustomSparkline: a row of bottom-aligned bars with rounded tops, PER-BAR colours, an optional highlighted bar, and optional labels underneath (e.g. day numbers). Unlike the QtCharts QCustomBarChart it carries no axes/grid/legend/toolbar and stays crisp at any size - perfect for a dashboard panel where each bar wants its own colour (idle / accent / a single highlighted value). Give data via setData([...]) in code, or the valuesCsv / colorsCsv / labelsCsv properties in Qt Designer.
