Graph

Namespace: DISPLIB  ·  Library: Display Library

#include <disp/graph.h>

class DISPLIB::Graph

Common base widget providing title, axis labels and resize handling for DISPLIB's QPainter plots.

Subclasses such as Plot and ImageSc paint inside the content rectangle that Graph leaves free after stamping the title bar at the top and the x / y axis labels on the bottom and left margins.

src/examples/ex_disp_plots/main.cpp
VectorXd samples = VectorXd::LinSpaced(50, -1.0, 1.0);
Plot plot(samples); // Plot is a Graph with title and axis labels
plot.setTitle("ramp");
plot.setXLabel("sample");
plot.setYLabel("value");
