The histogram shows a numeric value (the Y axis) against a distinct value (the X axis). The height of each column represents the value of the Y axis value.

A few points about the histogram:

- The X axis can be any kind of data, as long as they are distinct
- The Y axis must be numeric data (otherwise comparison is impossible), only SharePoint numeric list columns (include currency columns) are available for Y
- The histogram supports multi-series, meaning multiple sets of columns can be rendered in the same graph
- The histogramÂ supports live data updates from SharePoint, meaning when the underlying SharePoint list data changes, the graph will gracefully update itself

Here is an example of a single series histogram * (see below example live)*:

Here is an example of a multi-series histogram * (see below example live)*:

## Visual range

When rendering, the visualizer will determine the visual range on the Y axis from data, from example, if the minimum and maximum value from your data is 20 and 80, respectively, then the histogram’s Y axis will begin at 20 and end at 80.

Users have the option to override this range to be a more inclusive range, in the above example, users can set the range to be, say between 0 and 100.

Please note, the visualizer will **take into account both range user inputted and the data range from data**, and use the most inclusive range.

## Sorting

Data on the histogram can be sorted:

In the case of multi-series, sorting on the Y axis will only apply to the last (most recent) added data series. Sorting on the X axis is not affected by multi-series.
