matplotlib.pyplot

// functions of same dimensions as axes (vectors)
// plots only with 2 vectors / matrix of 2 cols

show() :
subplot(rows, cols, pos) : subplot at pos

• pos=index (1,2..)
• pos=(i,j) : (tuple) use from index i to j
• e.g.: graph made of r*c subgraphs, numbered 1..r*c, row by row

plot

loglog() : graph with logarithmic scale
plot(x, y, color=”string”, linewidth=INT, marker=’char’) :

• plot(x, y, “b*”) : color+marker

imshow(IMG, str cmap=, int vmin=, int vmax=) :

• add image to axis
• cmap : color
• cmap='gray' : grey mask
• vmin, vmax : values range

scatter() : graph as scatter points
semilogx() : graph with logarithmic scale (on x)
semilogy() : //

configure plot properties

axis(val) : set axises

• val="on" : show
• val="off" : don't show

figure(figsize=) : dimensions/size
grid() : configure stuff like grid lines
legend([list]) :
suptitle(string) :
title(string, fontsize=INT) : (accepts pseudo-latex text)

• title(“[-$\pi$, pi]”) : pi

xlabel(string) :
ylabel(string) :

misc

rc() : global configurations

• rc(“font”, size=INT) : font size

tight_layout() : adjust so all fit

• e.g.: labels dont overlap or go out
