Date formatting


In table charts and on x-axis labels, Chartio automatically formats dates into a more legible format when detected. Formatted date labels will be spaced evenly along the x-axis. In order for Chartio to recognize dates, they need to be formatted in a certain way in your query.

This formatting is automatically applied in Interactive Mode. In SQL Mode, please use the following input formats:

Date Bucket Input Format Default Output Format1

  1. X-axis label format will vary based on the width of your chart and the number of data points. For example, in a line chart with dates bucketed by day, the labels may be grouped by month to save space.

For more information on date formatting syntax, please see the documentation specific to your database type.

Custom date formats

For table charts, the date format can be set in your Chart Settings, in the Column Formatting tab.

At this time, it is not possible to customize the auto-generated date formatting on the x-axis.
