set — Update figure, axes, and plot-object properties through RunMat’s graphics handles and MATLAB-style set workflows.

set applies property/value pairs to plotting handles. In RunMat, it is the public write path for the shared graphics object model: you can update text handles, legend handles, axes handles, and plot-child handles such as lines, stems, error bars, histograms, images, contour objects, and more through a MATLAB-style set(h, 'Property', value) interface.

How set works in RunMat

• set requires a plotting handle followed by one or more property/value pairs.
• Different handle families accept different properties, and unsupported properties raise plotting errors rather than silently succeeding.
• Axes-local state such as limits, log modes, and legend visibility can be updated through axes handles.
• Plot-child properties such as line width, display names, marker styling, and selected object semantics are updated in place through the returned plot handles.
• Legend and text objects participate in the same property path, so figure annotation workflows stay consistent with the rest of the handle model.

Examples

Style a line after plotting

h = plot(0:0.1:1, (0:0.1:1).^2);
set(h, 'Color', 'r', 'LineWidth', 2, 'DisplayName', 'quadratic');

Update axes-local state through an axes handle

ax = subplot(1, 2, 2);
plot(1:5, [2 3 5 4 1]);
set(ax, 'XScale', 'log', 'Grid', false);

Change a legend after it has been created

plot(1:5, 1:5);
lg = legend('series');
set(lg, 'Location', 'southwest', 'Orientation', 'horizontal');
