Re: [Matplotlib-users] Date format the x-axis of a barh() plot?

2011-04-27 Thread jfortiv 

This worked.  Thank you very much!  For some reason I had commented out
ax.fmt_xdata = ...

This is exactly what I needed.

 Hi,

 This actually did not work for me.  Can you show me the full code that
 you
 used to successfully produce the time-format x-axis labels?

 Even with ax.fmt_xdata, I'm simply getting numbers on the x-axis instead

 dates.  Can anyone offer some pointers?

[Matplotlib-users] Date format the x-axis of a barh() plot?

val = mdates.drange(date1,date2,delta)   # the bar lengths
pos = range(len(val))# the bar centers on the y axis
height=0.5# the bar height
left=mdates.drange(date1,date2,delta)# the bar starting position

fig = plt.figure()
ax = fig.add_subplot(111)
ax.barh(pos,val,height=height,left=left,align='center',alpha=0.3)
