Troubles configuring a barchart

[hergin]

The Bar value should be something like this:
Search for Users: each item's current_level: unique elements: sorted: format as text
Then, in the format as text box below:

• content to show ... will be Search for Users (current_level = this number): count and
• delimiter will be , (comma only).

The explanation is: you already had the X-axis labels as the current_levels, now for each level, you have to find user count and separate them with commas for the bar value field.
