Dear developers,
I found a very easy way of creating a horizontal bar chart, which can
also be easily animated. I wondered if this could be useful for anyone
else, so here is the code:
def hbarplot(a,b):
y1 = 0
y2 = -b[0]
P = polygon([[0,y1],[0,y2],[a[0],y2],[a[0],y1]])
for i in srange(1,len(a)):
y1 = y2
y2 = y2 - b[i]
P += polygon([[0,y1],[0,y2],[a[i],y2],[a[i],y1]])
return P
The first argument is a list of values for the horizontal bar lenghts
and the second is a list of bar thicknesses. The plot will start at
the top and stack the bars negatively to illustrate e.g. soil
profiles, but this could be changed easily.
Example animation:
animate(hbarplot([i,6],[0.5,0.5]) for i in srange(5)).show()
It took me 15 minutes to code this up, while it took me a lot longer
to try out pylab's animations and bar charts before giving up on that.
Cheers
Stan
