# Format Chart Axis Position

You can add a second y-axis, or change the position of the y-axis on a chart. For horizontal charts, you can add a second x-axis or change the position of the x-axis instead.

Formatting the chart axis is available for the following visualisation types:

* [bar-chart](https://support.meetuma.ai/uma-knowledgebase/data-and-reporting/analytics-pro/charts/build-a-chart/bar-chart "mention")
* [box-and-whisker-chart](https://support.meetuma.ai/uma-knowledgebase/data-and-reporting/analytics-pro/charts/build-a-chart/box-and-whisker-chart "mention")
* [combo-chart](https://support.meetuma.ai/uma-knowledgebase/data-and-reporting/analytics-pro/charts/build-a-chart/combo-chart "mention")
* [line-chart](https://support.meetuma.ai/uma-knowledgebase/data-and-reporting/analytics-pro/charts/build-a-chart/line-chart "mention")
* [scatter-plot](https://support.meetuma.ai/uma-knowledgebase/data-and-reporting/analytics-pro/charts/build-a-chart/scatter-plot "mention")
* [waterfall-chart](https://support.meetuma.ai/uma-knowledgebase/data-and-reporting/analytics-pro/charts/build-a-chart/waterfall-chart "mention")

### Change the position of the chart axis

After adding at least one column to the y-axis (for vertical charts) or the x-axis (for horizontal charts), you can change the position of the axis.

1. In the editor panel, hover over the y-axis column name, then click the caret (![](https://sigma-docs-screenshots.s3.us-west-2.amazonaws.com/Icons/caret.svg)) to open the column menu.
2. For **Axis**, select the image that shows the axis in the position that you want.<br>

   The chart updates with the axis in the new position.

### Add a second chart axis

For charts that visualise at least two columns on the y-axis (for vertical charts) or the x-axis (for horizontal charts), you can add a second chart axis.

**Before you start:** This action uses the editor panel. If you have not done so already, open the editor panel from either Explore or Edit mode.

1. In the editor panel, hover over the y-axis column name, then click the caret (![](https://sigma-docs-screenshots.s3.us-west-2.amazonaws.com/Icons/caret.svg)) to open the column menu.
2. For **Axis**, select the image that shows the axis in the position that you want.<br>
