More digits on the plot window coordinate display?

Community matplotlib-users

Is there a way to display more digits on

the cursor readout in the lower right hand corner of the plot window?
Right now my setup is only showing three digits to the right of the decimal
point, which isn’t enough when I’m zoomed way in. If that
description isn’t good enough to describe what I mean, take a look at the
following screenshot:

…or maybe I’m looking for a way to trace the
individual displayed waveforms with the cursor, like on a digital oscilloscope,
to ease in the taking of measurements. Any thoughts?

Thanks,

Greg

Something like this (pylab-style example):

def fmt(x):
     return "%10.5f" % x

ax = gca()
ax.fmt_xdata = fmt
ax.fmt_ydata = fmt

If the fmt_xdata and/or fmt_ydata attributes of the axes object are callable, they are used to format the cursor readout.
