# Repeat By

With Repeat By, you can show multiple charts by groups at a time on the same chart area. It is useful to capture/compare the trends and characteristics of groups at a glance.

The Repeat By feature is available for following chart types.

* Bar
* Line
* Area
* Histogram
* Scatter (No Aggregation)
* Scatter (With Aggregation)
* Error Bar

## Using Repeat By

You can assign a column you want to group by and repeat at the Repeat By control. Values in the assigned column are treated as discrete values (as text).

## Repeat By Y-Axis Columns

If you assign multiple columns to Y-Axis, you can treat those columns as groups and repeat the chart by those columns.

You can choose "(Each Y Axis)" option shows up in the Repeat By dropdown. This option shows up when you have assign multiple columns to Y-Axis.
