# Multiple Y-Axis Columns

The Multiple Y-Axis feature is available on Bar, Line, Area and Scatter (No Aggregation) charts. You can assign multiple columns to Y-Axis on those charts.

## How to Add Y-Axis

For charts that support Multiple Y-Axis, you see the plus ("+") sign right next to the "Y Axis:" label.

You can click that plus sign to add another Y-Axis to the chart.

You can remove unnecessary Y-Axis by clicking the dropdown menu from on the target Y-Axis and selecting `Delete` item.

Note that you cannot remove Y1-Axis.

## Color

You cannot assign multiple columns to Y-Axis and a column for Color at the same time. As soon as you assign multiple columns to Y-Axis, the column assignment for Color will be removed if there's any, and Color control will be disabled.

But you can still change the color scheme from the Color dialog. See [Color](https://docs.exploratory.io/visualization/features/color) section for the detail about Color.
