How to avoid tick duplicates when using tickFormatter?

[dmdum]

I'm using tickFormatter to to change how the ticks are displayed. I would like it so there are no duplicates after the ticks are transformed. Using allowDuplicatedCategory: false doesn't seem to work for tickFormatter.

Is there any other way I can avoid duplicates?
Thank you.

allowDuplicatedCategory only respects the actual values given to the chart. You will have to dedupe yourself in that case

I see, thank you!
