GUI Chart

App: apps/gui_chart/

Demonstrates both Nuklear chart types: an animated line chart driven by a sine wave, and a column chart with static data.

Run from root

% ./plume3d gui_chart

What it shows

• Line chart (type=0) — 30 data points pushed each frame from Math.sin(_time * 2 + i * 0.4), giving a scrolling animated wave. Range: −1 to 1.
• Column chart (type=1) — 10 fixed values in 0–100 range, rendered as vertical bars.
• Uses chartBegin / chartPush / chartEnd pattern — push exactly count values between begin and end.

Key patterns

// Animated sine wave
Gui.layoutRowDynamic(150, 1)
if (Gui.chartBegin(0, 30, -1, 1)) {  // type=0 (line), 30 points
    for (i in 0...30) {
        Gui.chartPush(Math.sin(_time * 2 + i * 0.4))
    }
    Gui.chartEnd()
}

// Static column chart
if (Gui.chartBegin(1, _data.count, 0, 100)) {  // type=1 (column)
    for (v in _data) Gui.chartPush(v)
    Gui.chartEnd()
}

• Gui — chartBegin, chartBeginColored, chartPush, chartEnd.
