small patch to enable formatters for contour line labels

Community matplotlib-users
1

The function “clabel” does not allow the use of formatters for the label; this small patch enables their use, so that one can pass in any subclass of ticker.Formatter in the ‘fmt’ argument.

Replace the following in contour.py:

def get_text(self, lev, fmt):
    "get the text of the label"
    if cbook.is_string_like(lev):
        return lev
    else:
        if isinstance(fmt,dict):
            return fmt[lev]

        else:
            return fmt%lev

With the following:

def get_text(self, lev, fmt):
    "get the text of the label"
    if cbook.is_string_like(lev):
        return lev

    else:
        if isinstance(fmt,dict):
            return fmt[lev]
        elif isinstance(fmt,ticker.Formatter):
            return fmt(lev)

        else:
            return fmt%lev

As you can see, there is only a two line change, but it does enable formatters. Perhaps one of the devs can put this in?

Yes, I have it done at home, and when I am a little more confident I know how to interact with github, I will push it up.

Replace the following in contour.py:
