Package limn.components.chart

package limn.components.chart

Charts: BarChart, LineChart and DonutChart, over a shared Chart that carries the data, the palette, the legend, the tooltip, the click callback and the animation.

Every chart is a plain widget: it measures, lays out and paints like any other, takes its ink from the active theme, and needs nothing configured to be readable. Feed it labels and a ChartSeries and it picks colors, rounds the scale, draws the legend and animates the values in.

 BarChart chart = new BarChart();
 chart.setLabels("Mon", "Tue", "Wed");
 chart.addSeries(ChartSeries.of("Signups", 12, 19, 3));
 chart.onPointClick(point -> status.setText(point.label()));

Package	Description
limn.components	Ready-to-use components (Label, Button, TextField, Checkbox/Switch, Dialog) and the light/dark Theme.
limn.components.text	The headless editing engine behind the text components: TextEditModel owns the buffer, the caret, the anchor-based selection, line movement with a sticky goal column and bounded undo/redo, stepping by grapheme cluster so combining marks and ZWJ emoji are never split.

ChartAxis	One axis of a CartesianChart: the value axis that carries the numbers, or the category axis that carries the labels.

ChartPalette	The colors a chart hands to its series (or, in a donut, to its slices) when the application names none.
ChartPoint	One datum a chart can point at: what was hovered, what was clicked, what a tooltip row is about.
