Hi,

 

I have been trying to leverage plot_date() to generate time trends. I
seem to run into the following runtime error and don't have much
insight as to why this is happening. Specifically, I don't quite see why
the function is attempting to set the lower bound to 0001-01-01 UTC when
my x-axis starts only from day number 729390. 

I am using Python 2.4 and Matplotlib 1.0.1

 

In [131]: date_num = date2num(dates)

 

In [132]: date_num

Out[132]: 

array([ 729390.,  729391.,  729392.,  729393.,  729394.,  729395.,

        729396.,  729397.,  729398.,  729399.])

 

In [133]: plot_date(date_num,range(10))

 

RuntimeError: RRuleLocator estimated to generate 2012 ticks from
0001-01-01 00:00:00+00:00 to 2012-02-04 17:46:21.028099+00:00: exceeds
Locator.MAXTICKS * 2 (2000)

 

 

Any help will be much appreciated.

 

Thanks,
Shankar

 

 

 

Dear users Matplotlib 
I am new to Matplotlib and would like to know
how the code below I can set the command to plot the spline instead of
straight lines. 

# -- Plot the reaction path
import pylab as p
fig =
p.figure(1)
sp = p.subplot(1,1,1)

p.plot(range(len(Epath)), Epath,
's-')

for idx, (E,label) in enumerate(zip(Epath,PathLabels)):

p.text(idx, E, label,
 horizontalalignment='center',

verticalalignment='top')

p.title('H2O disassociation')
p.ylabel('Energy
[eV]')
p.xlabel('Reaction path')
p.xlim([-0.5, 2.5])
p.ylim([-0.5,
1.5])
sp.get_xaxis().set_ticks([]) # Turn off ticks on
xaxis

p.show()
