Labels alphabetically before bucket break Histogram

[djetelina]

One of the possible fixes:

def label_group(self, value):
    if TYPES.HISTOGRAM_BUCKET == value[0][0]:
        return [x for x in value[0][3] if x[0] != 'bucket']
    return value[0][3]

Other could be sorting bucket always first I guess, took me a while to find at least this fix.

Nope, there is sorter method, which also works specially with HistogramBuckets. You have to update it to:

    def skip_bucket(self, value):
        return tuple(x for x in value[0][3] if x[0] != 'bucket')

    def label_group(self, value):
        if TYPES.HISTOGRAM_BUCKET == value[0][0]:
            return self.skip_bucket(value)
        return value[0][3]

    def sorter(self, value):
        if TYPES.HISTOGRAM_BUCKET == value[0][0]:
            return value[0][1], self.skip_bucket(value), value[0][0]
        return value[0][1], value[0][3], value[0][0]
