Thanks for the inkscape suggestion - I usually just use eps and pdf
which I find harder to edit.
Below is the function I use to create the plot. Actually I thought it
happened with all legends, but I think I have just been focussing on
these plots for too long, because when I check now it only seems to
happen when I plot with this function.
plot_stacked(arange(1,6),arange(1,6)) should reproduce the problem.
Perhaps it is something to do with setting the labels to '' to delete
the duplicate copies I don't want?
Thanks,
Robin
def plot_stacked(*vals, **kwargs):
fig = figure()
sub = fig.add_subplot(111)
ticks = kwargs.setdefault('ticks',[])
labels = kwargs.setdefault('labels',False)
numstacks = len(vals)
vallength = set([len(val) for val in vals])
if len(vallength) > 1:
raise ValueError,'All input values should have the same length'
vallength = vallength.pop()
ind = 0.25 + arange(numstacks)
width = 0.5
bottom = zeros(numstacks)
colorvals = arange(vallength) * (1.0/(vallength-1))
orderlabels = ['First Order','Second Order','Third Order','Fourth Order']
if not labels:
labels = orderlabels[:vallength-1] + ['Higher Order']
for i in range(vallength):
ivals = [val[i] for val in vals]
sub.bar(ind, ivals, width,
bottom=bottom, color=str(colorvals[i]),label=labels[i])
bottom += ivals
sub.set_xlim(0,numstacks+1.5)
sub.set_xticks(ind+width/2)
sub.set_xticklabels(ticks)
# remove duplicate labels
tmplabels = []
for rect in sub.patches:
if rect.get_label() in tmplabels:
rect.set_label('')
else:
tmplabels.append(rect.get_label())
sub.legend()
fig.show()
