Greetings,

Love this visual too much to not mention something. There seems to be a weird quirk in the most recent version of the histogram custom visual. Records with identical values aren't being counted in the histogram.

Now Histogram custom visual supports only few thousands of rows. Number of provided rows is not proportional to the number of visual elements of the visual, so there should be no performance issues in regards of displaying them. There can be issues with creating selectionIds - this problem might be also resolved by using other selection/filtering approach.

Such changes will allow to support more number of rows and improve performance of the visual.

Please add support for displaying the X axis with percentages. For example business cases: % of Target Pay, % of Sales Goal, etc.

I have noticed that when not specifying frequencies, the sum of all frequency does not equal with the count of all input data.

In the official example on the usage of this visualization it can be perfectly seen, that the sum of frequencies on the 'Students exam result' page does not equal with the count of all students.

Bins: [7,12], (12,17], (17,22], (22,27], (27,32], (32,37], (37,42], (42,47], (47,52], (52,57], (57,62], (62,67], (67,72], (72,77], (77,82], (82,87], (87,92], (92,97]
Correct:   [1, 1, 1, 1, 2, 3, 4, 3, 2, 9, 9, 8, 6, 5, 1, 1, 1, 2]
By Visual: [1, 1, 1, 1, 2, 2, 2, 2, 2, 4, 3, 5, 3, 3, 1, 1, 1, 2]

The sum is not even 60 in case of this visual. It seems that value on the border are skipped (in spite the fact the the border is closed) in some cases.

When specifying properties for the X-Axis, you can set Start and End. When in my example I set Start to 0 and End 100, the chart X Axis displays values between -7 and 101
