Control the X-axis labels length

What is the problem or goal the end user is trying to solve or accomplish?

If the names for the X-axis labels (for example, the dimension values for a Bar Chart) are too long, they might look unappealing in the Chart.

How are they solving it currently?

Depending on the DB Engine it's possible to manipulate the column length or use functions like substring().

What is the recommended solution by the Customer?

Provide the ability to configure the label length on the UI or even re-name them.
