# Bar and Horizontal Bar Chart

## Introduction

The **Bar Chart** displays data of one or more series as bars:

By changing the chart typ to **Horizontal Bar Chart** the chart changes to the specified type. No other changes, besides optionally changing the *Number Formatter Y-Axis* settings to the *Number Formatter X-Axis* settings and vice versa:

## Expected Data and Graph Designer

The Bar Chart expects data in a two (or more) column format such as:

| Date       | Revenue | Cost |
| ---------- | ------- | ---- |
| 23 January | 38      | 24   |
| 24 January | 39      | 24   |
| 25 January | 40      | 24   |
| 26 January | 40      | 24   |

In the Graph Designer you can then select the column you want to use for your x-axis (for the Horizontal Bar Chart the selected x-axis will be the y-axis):

![Graph Designer X-Axis](https://s3.amazonaws.com/cdn.freshdesk.com/data/helpdesk/attachments/production/48074829415/original/qu47HrdnVzEKhKYOqgdCyLuKw6Wl8umWwg.png?1607361230)

Hence, the x-axis column does not need to be the first column. However, for consistency purposes it is recommended to always use your first column for the x-axis.

For each column, besides the one used by the x-axis one bar will be displayed.
