Bar Chart where to specify number of decimals on XAxis and format data shown?

Hi,

I am working on a bar chart and I want the data to display differently than it is shown now. I can find the format property for the yAxis, but nothing for the xAxis, where do I modify how that data is shopwn?

You can see a sample of the current chart in the picture attached.

For example we only want a portion of the date to show.

Kind Regards
