Categorise Bar Chart

How to create a bar chart by setting the static category myself?

I mean, for example, I have a dataset which record the number of coins different people have.

I would like to draw a bar chart which shows 3 bars with the following 3 different categories:

1) n < 5,

2) n >= 5 and n <10,

3) n>=10.

where n is the number of coins.

How can this be expressed in the categories grouping?

Thanks in advance.

Sorry, this is currently not directly supported through chart groupings. You would need to write the query (or add a calculated field on the dataset) so that you get this categorization in the data and then use those fields in the chart.
