The value_format of a Dimension is not applied to HoloMap widgets

[mrksr]

A kdim of a HoloMap can have a value_format-function. While this function does get applied to labels, the drop-down menu rendered into a jupyter notebook seems to not be affected.

Sample Code:

def data():
    return hv.Curve(np.cumsum(np.random.normal(size=(30))))

hv.HoloMap({
    'a': data(),
    'b': data(),
    'c': data()
}, kdims=[hv.Dimension("Letter", value_format=lambda x: "formatted: {}".format(x))])

Thanks for filing an issue on this. The same is true for the slider values which should in theory also support string labels, e.g. when working with timestamps that get formatted as a date. Hopefully we can get this into the next bugfix release.

This has been fixed in #562. Closing.
