Plot Gallery

This Wiki is open to the public and everyone can edit it. I encourage people to share their plot examples as well as the corresponding code. Each example should have a title to briefly describe it and an unique increasing identifier. Please use the example #0 as the template.

#0 Surface plot with different altitude and azimuth

let x, y = Mat.meshgrid (-2.5) 2.5 (-2.5) 2.5 100 100 in
let z = Mat.(sin ((x * x) + (y * y))) in
let h = Plot.create ~m:1 ~n:3 "gallery_000.png" in
Plot.subplot h 0 0;
Plot.(mesh ~h ~spec:[ Altitude 50.; Azimuth 120. ] x y z);
Plot.subplot h 0 1;
Plot.(mesh ~h ~spec:[ Altitude 65.; Azimuth 120. ] x y z);
Plot.subplot h 0 2;
Plot.(mesh ~h ~spec:[ Altitude 80.; Azimuth 120. ] x y z);
Plot.output h;;

#1 Visualise the sparsity of matrices

let x = Mat.bernoulli ~p:0.1 40 40 in
let y = Mat.bernoulli ~p:0.2 40 40 in
let z = Mat.bernoulli ~p:0.3 40 40 in
let h = Plot.create ~m:1 ~n:3 "gallery_001.png" in
Plot.subplot h 0 0;
Plot.spy ~h x;
Plot.subplot h 0 1;
Plot.spy ~h y;
Plot.subplot h 0 2;
Plot.spy ~h z;
Plot.output h;;
