When to use it

Shared rendering engine for horizontal bars, bubbles, candles, radar, pie and diverging bars. This is an advanced infrastructure-level API.

Designer Properties

This module does not declare Designer Properties.

Creation and lifecycle

Dim R As JChartRenderer
R.Initialize(0) '0 = horizontal bars
R.Create(HostPanel)

Dim Rows As List
Rows.Initialize
Dim Row As Map = CreateMap("label":"Sales", "value":75, "color":0xFF4F46E5)
Rows.Add(Row)
R.SetRows(Rows, Null)
R.SetTitle("Overview")

Working example

Dim R As JChartRenderer
R.Initialize(0) '0 = horizontal bars
R.Create(HostPanel)

Dim Rows As List
Rows.Initialize
Dim Row As Map = CreateMap("label":"Sales", "value":75, "color":0xFF4F46E5)
Rows.Add(Row)
R.SetRows(Rows, Null)
R.SetTitle("Overview")

Normalized B4X properties

Compatible public getX/setX accessors are presented as normal B4X properties. Parameterized accessors remain documented as methods.

There are no simple get/set pairs that map to B4X properties.

Events

No public events are declared in the analyzed version.

Export and rendering

When the module exposes SaveAsPNG / SavePNG, the rendered control can be saved directly to PNG. Check the returned Boolean when provided.

Source-backed notes for the analyzed version

ChartKind values in source: 0 horizontal bars, 1 bubbles, 2 candles, 3 radar, 4 pie, 5 diverging bars.
SetRows expects Maps whose keys depend on ChartKind; prefer the higher-level chart wrappers unless you need renderer-level control.
