Dear All,
I am concerned there could be a bug in errorplot for pylab.
I am running Debian testing (the amd64 release) on my box.
Some time ago I posted about a possible bug in pylab and the
workaround I found (since I prefer to use Debian repositories rather
than matplotlib CVS version) was to add a clf() command at the end of
the figure.
Consider the following plot (taken directly from my code):
p.plot(time[ini_conf:fin_conf],my_fractal_dim,"k^")
p.xlabel('Dimensionless Time',fontsize=20)
labels = p.getp(p.gca(), 'xticklabels')
p.setp(labels, color='k', fontsize=15)
p.ylabel('Fractal Dimension',fontsize=20)
labels2 = p.getp(p.gca(), 'yticklabels')
p.setp(labels2, color='k', fontsize=15)
#p.legend(('from power-law fitting','from linear fitting on log-log'))
#p.title('Evolution Fractal Dimension')
p.grid(False)
#cluster_name="number_cluster_vs_time2%05d"%my_config
cluster_name="Evolution_fractal_dimension-no-mean.pdf"
p.savefig(cluster_name)
p.hold(False)
p.clf()
print 'delta_df is,', delta_df
print 'my_fractal_dim is,', my_fractal_dim
#p.errorbar(time[ini_conf:fin_conf],my_fractal_dim,yerr=delta_df,marker='s',mfc='red',
mec='green', ms=20, mew=4 )
p.errorbar(time[ini_conf:fin_conf],my_fractal_dim,yerr=delta_df )
p.xlabel('Time')
p.ylabel('Fractal dimension')
#p.legend(('from power-law fitting','from linear fitting on log-log'))
#p.title('Evolution Fractal Dimension from R_g')
#p.grid(True)
#cluster_name="number_cluster_vs_time2%05d"%my_config
#cluster_name="std_err_D_f.pdf"
p.savefig("time_evolution_D_f_with_error_bars.pdf")
p.hold(False)
p.clf()
I am basically plotting two figures, but errorbar is not returning any
vertical bar giving uncertainties. Instead, if I swap the two plots
(i.e. first the errorbar and then the normal plot) I see a nice plot
with error bars.
This can be quite annoying (it is already tough enough to carry out
computations without thinking about when I should plot what).
Has anyone else experienced anything similar?
Suggestions are really welcome.
Cheers
Lorenzo
