Hi, I've been experimenting with a simple idea for specifying plot layout in a rather intuitive way. The idea is simply to "draw" your layout using strings. Examples: layout = ["AB"] -> means two plots side by side with equal width layout = ["AAAB"] -> means two plots side by side A being 3 times wider than B layout = ["AB", "CC"] -> means two plots (A & B) side by side and C below with full width layout = ["AB", "C "] -> means two plots (A & B) side by side and C below A (same width) etc... (have a look at sources) I guess you cannot express every layout but it might work for most common ones. If you think this might a good addition I can try to make a PR but I'm not sure where to insert it. My idea would be to have a layout function such that you can write: A,B,C = plt.layout(["AB", "CC"], border=0.01) A.plot(...) B.plot(...) C.plot(...) Nicolas |
def parse(layout, border=0.02):
plots = {}
for y,line in enumerate(layout[::-1]):
for x,letter in enumerate(line):
if letter == ' ':
continue
if letter in plots.keys():
(x_start,y_start), (x_stop,y_stop) = plots[letter]
x_stop = max(x+1,x_stop)
y_stop = max(y+1,y_stop)
plots[letter] = [(x_start,y_start),
(x_stop,y_stop)]
else:
plots[letter] = [(x,y), (x+1,y+1)]
width = float(len(layout[0])*(1+border))
height = float(len(layout)*(1+border))
for key, value in plots.items():
(x_start,y_start), (x_stop,y_stop) = value
x = x_start / width
w = (x_stop-x_start) / width
y = y_start / height
h = (y_stop-y_start) / height
plots[key] = x+border, y+border, w-border, h-border
return [(name, extents) for name,extents in plots.items()]
# A,B side by side
layout = ["AB"]
# A,B, side by side, A 3 times bigger than B
# layout = ["AAAB"]
# A,B side by side, C below (full width)
layout = ["AB",
"CC"]
# A,B side by side, C below A
layout = ["AB",
"C "]
# B within A
layout = ["AAAAA",
"AAAAA",
"AAABB",
"AAABB"]
import matplotlib.pyplot as plt
for name, extents in parse(layout):
plt.axes(extents)
plt.xticks([]), plt.yticks([])
plt.text(0.5,0.5, name, ha='center', va='center', size=32)
plt.show()
