One should be able to write a specific example that exposes this
functionality fairly easily using callback event handling. I'll
provide a simple example using a line plot to get the approximate
ylimits of the data based on the xaxis zoom limits, and maybe some
enterprising developer can extend this example to an image which sets
the clim based on the xlim and ylim
from pylab import nx, figure, show
t = nx.arange(0.0, 2.0, 0.1)
s = nx.sin(2*nx.pi*t)
fig = figure()
ax = fig.add_subplot(111)
ax.plot(t, s)
def on_xlim(ax):
xmin, xmax = ax.get_xlim()
imin, imax = nx.searchsorted(t, (xmin, xmax))
thiss = s[imin:imax]
ax.set_ylim(min(thiss), max(thiss))
ax.figure.canvas.draw()
ax.connect('xlim_changed', on_xlim)
show()
