29.18.6 Polar Heatmap

Polar-Heatmap

Data Requirements

• Worksheet: Select XY columns or XYZ columns (full or subrange); or a virtual matrix.

or

• Matrix: A matrix sheet. Multi-object sheet is supported.

Creating the Graph

Activate the matrixsheet or select required data from worksheet:

• From the menu, choose Plot > Contour: Polar HeatMap θ(X)r(Y).

When you create the polar heatmap from XY data, the dialog plot_heatmapxy will be opened.

When you create the polar heatmap from XYZ data, the dialog plot_heatmapxyz will be opened.

When you create the polar heatmap from multiple Y columns without Z, the dialog plotvm dialog be opened.

Template

PolarheatmapMat.otpu

(Installed to the Origin program folder).

Notes

The polar heatmap is similar with heatmap, but plotted into a polar coordinate.

• When you choose Plot > Contour: Polar HeatMap θ(X)r(Y), all X and Y in label will be changed as θ and R in the X-function dialog plot_heatmapxy, plot_heatmapxyz and plotvm.
• It supports to create a polar heatmap with RGB values in the source Z column or matrix.
