public class KlynPlotWidget extends Canvas

Widget

└ Canvas

└ KlynPlotWidget

Embeddable scientific plot, drawn with the Klyn Painter (2D, pie or 3D scatter). The default style uses a white figure, 5% data margins, outward ticks, a ten-color cycle and point-based line sizes. No external plotting library is needed by applications. In 3D, drag with the left mouse button to rotate, middle to pan and right to zoom. These interactions also work when the plot is embedded in a layout.

chart = KlynPlotWidget()
chart.plot([0.0, 1.0, 2.0], [0.0, 1.0, 4.0], label="square")
window.centralWidget.add(chart)

Properties

Modifier and Type	Member	Description
public readonly property	projection `projection as String`	Projection selected at construction: "2d" or "3d".
public readonly property	seriesCount `seriesCount as Int`	Number of plotted datasets; a pie counts as one.
public property	title `title as String`	Plot title, distinct from the native window title.
public property	xLabel `xLabel as String`	Horizontal axis label.
public property	yLabel `yLabel as String`	Vertical axis label.
public property	zLabel `zLabel as String`	Third axis label; available on a 3D chart.

Constructors

Modifier and Type	Member	Description
public	KlynPlotWidget `KlynPlotWidget(projection as String = "2d")`	Creates a 640x480 plot canvas.

Methods

Modifier and Type	Member	Description
public	autoscale `autoscale() as Void`	Restores automatic limits on both axes.
public	clear `clear() as Void`	Removes curves or a pie and resets color cycles and axes.
public	colorbar `colorbar(label as String = "", visible as Boolean = true) as Void`	Displays the most recently inserted scalar-colored scatter's scale.
public	exportImage `exportImage(path as Path, width as Int = 640, height as Int = 480) as Void`	Exports the plot without changing its widget geometry.
public	grid `grid(visible as Boolean = true) as Void`	Shows or hides major grid lines.
public	legend `legend(location as String = "best", visible as Boolean = true) as Void`	Shows a legend, choosing a low-overlap corner by default.
public override	paint `paint(painter as Painter) as Void`	Draws into the assigned widget bounds.
public	pie `pie(values as IList<Double>, labels as IList<String> = null, explode as IList<Double> = null, autopct as String = "", shadow as Boolean = false, startAngle as Double = 0.0, counterClockwise as Boolean = true, colors as IList<String> = null) as Void`	Displays a circular pie from copied, non-negative weights in list order.
public	pie `pie(values as NDArray<Double>, labels as IList<String> = null, explode as IList<Double> = null, autopct as String = "", shadow as Boolean = false, startAngle as Double = 0.0, counterClockwise as Boolean = true, colors as IList<String> = null) as Void`	Displays a pie from a copied one-dimensional array, with the list overload's options.
public	plot `plot(x as IList<Double>, y as IList<Double>, format as String = "", label as String = "", color as String = "", lineWidth as Double = 1.5) as Void`	Adds a curve from lists, with the same options as the NDArray overload.
public	plot `plot(x as NDArray<Double>, y as NDArray<Double>, format as String = "", label as String = "", color as String = "", lineWidth as Double = 1.5) as Void`	Adds a curve from one-dimensional arrays; inputs are copied.
public	resetView `resetView() as Void`	Restores the default 3D camera, pan and zoom without removing data.
public	scatter `scatter(x as IList<Double>, y as IList<Double>, label as String = "", color as String = "", size as Double = 36.0, values as IList<Double> = null, sizes as IList<Double> = null, colorMap as String = "coolwarm", vmin as Double = nan, vmax as Double = nan, sortByValue as Boolean = false) as Void`	Adds circular markers from lists.
public	scatter `scatter(x as IList<Double>, y as IList<Double>, z as IList<Double>, label as String = "", color as String = "", size as Double = 20.0) as Void`	Adds a 3D scatter series from copied lists, with the same options as arrays.
public	scatter `scatter(x as NDArray<Double>, y as NDArray<Double>, label as String = "", color as String = "", size as Double = 36.0, values as IList<Double> = null, sizes as IList<Double> = null, colorMap as String = "coolwarm", vmin as Double = nan, vmax as Double = nan, sortByValue as Boolean = false) as Void`	Adds circular markers from one-dimensional arrays.
public	scatter `scatter(x as NDArray<Double>, y as NDArray<Double>, z as NDArray<Double>, label as String = "", color as String = "", size as Double = 20.0) as Void`	Adds a 3D scatter series, copying one-dimensional arrays of equal length.
public	scatter `scatter<T>(x as NDArray<T>, y as NDArray<T>, label as String = "", color as String = "", size as Double = 36.0, values as NDArray<T> = null, sizes as NDArray<T> = null, colorMap as String = "coolwarm", vmin as Double = nan, vmax as Double = nan, sortByValue as Boolean = false) as Void`	Adds a scatter directly from typed numeric vectors and optional attribute tensors.
public	view `view(elevation as Double = 30.0, azimuth as Double = -60.0) as Void`	Sets the 3D camera angles in degrees, looking at the centre of the data box.
public	xLim `xLim(low as Double, high as Double) as Void`	Sets finite increasing x limits.
public	yLim `yLim(low as Double, high as Double) as Void`	Sets finite increasing y limits.
public	zLim `zLim(low as Double, high as Double) as Void`	Sets finite increasing z limits on a 3D chart.
