Matplotlib so log axis only has minor tick mark labels at specified points. Also change size of tick labels in colorbar

Question

I am trying to create a plot but I just want the ticklabels to show as shown where the log scale is shown as above. I only want the minor ticklabel for 50, 500 and 2000 to s

Answer 1

Based on the answer from @Paul I created the following function:

def get_formatter_function(allowed_values, datatype='float'):
    """returns a function, which only allows allowed_values as axis tick labels"""
    def hide_others(value, pos):
        if value in allowed_values:
            if datatype == 'float':
                return value
            elif datatype == 'int':
                return int(value)
        return ''
    return hide_others

Which is a bit more flexible.
