Re: [Matplotlib-users] Dynamically change X time format while zooming plot?

[Skip M. <sk...@po...>]

Let me return to my FuncFormatter usage.  As I indicated in an earlier
post, I made a single format decision based on the x range of the
entire data set.  The decision code was straightforward:

    x_delta = x_range[1] - x_range[0]
    if x_delta > int(1.5 * 365) * ONE_DAY:
        xfmt = "%Y-%m-%d"
    elif x_delta > 2 * ONE_DAY:
        xfmt = "%m/%d\n%H:%M"
    elif x_delta < 2 * ONE_HOUR:
        xfmt = "%H:%M:%S"
    else:
        xfmt = "%H:%M"

How do I compute x_delta as it relates to the currently visible
window?  In the above code, x_range represents the x range of my
entire data set.

Thx,
