hi all,
i'm tring to wrote some code to do a stem plot from a dictionary of array.
the code is :
def multi_stem_plot(self, key, name, title="", time_min="", time_max=""):
""" doc """
rows = len(key)
cols = 1
gr = str(rows)+str(cols)
for i in enumerate(key):
ylabel = key[i[0]].keys()[0]
data = key[i[0]][key[i[0]].keys()[0]]
data[np.isnan(data)]=0
nn = i[0] + 1
ngr = str(gr)+str(nn)
subplot(int(ngr))
subplots_adjust(left=0.125, bottom=0.1, right=0.9, top=0.9, \
wspace=0.2, hspace=0.5)
x_p = data[0][np.where(data[1]>=0)[0]]
y_p = data[1][np.where(data[1]>=0)[0]]
x_n = data[0][np.where(data[1]<0)[0]]
y_n = data[1][np.where(data[1]<0)[0]]
markerline, stemlines, baseline = stem(x_p, y_p, 'r-')
setp(markerline, 'markerfacecolor', 'b')
setp(baseline, 'color', 'r', 'linewidth', 2)
setp(stemlines, 'linewidth', 1)
markerline, stemlines, baseline = stem(x_n, y_n, 'b-')
setp(markerline, 'markerfacecolor', 'b')
setp(baseline, 'color', 'r', 'linewidth', 2)
setp(stemlines, 'linewidth', 1)
setp(gca(), 'ylabel', ylabel)
setp(gca(), 'title', 'Climate Indices : '+str(ylabel))
grid()
setp(gca(), 'xlabel', 'Year')
#if time_min or time_min != "":
# setp(gca(), 'xlim', [time_min,time_max])
fig = name+'.png'
savefig(fig)
show()
this line :
#if time_min or time_min != "":
# setp(gca(), 'xlim', [time_min,time_max])
generate this error :
NotImplementedError: 'Not implemented for this type'
function main in Climate.py at line 178
Climate().multi_stem_plot(md, 'Climate Indices', data_min, data_max)

if (not np.isfinite(vmin)) or (not np.isfinite(vmax)):
While this function works for a single plot :
def stem_plot(self, data, name, time_min="", time_max=""):
""" doc """
data[np.isnan(data)]=0
x_p = data[0][np.where(data[1]>=0)[0]]
y_p = data[1][np.where(data[1]>=0)[0]]
x_n = data[0][np.where(data[1]<0)[0]]
y_n = data[1][np.where(data[1]<0)[0]]
markerline, stemlines, baseline = stem(x_p, y_p, 'r-')
setp(markerline, 'markerfacecolor', 'b')
setp(baseline, 'color', 'r', 'linewidth', 2)
setp(stemlines, 'linewidth', 1)
markerline, stemlines, baseline = stem(x_n, y_n, 'b-')
setp(markerline, 'markerfacecolor', 'b')
setp(baseline, 'color', 'r', 'linewidth', 2)
setp(stemlines, 'linewidth', 1)
grid()
if time_min or time_min != "":
setp(gca(), 'xlim', [time_min,time_max])
setp(gca(), 'xlabel', 'Year', 'ylabel', name)
fig = name+'.png'
savefig(fig)
print 'indicator : ', name
show(
Have you any clue on how to fix my error ?
Many thanks!
