Need a scatter plot with categorical axis

Hello everyone,

I need for a project a scatter/bubble plot but I have two problems so far :

- Both axis are text values

- I want to display the number of element in each dot

I get to this result by adapting my data :

I changed my text category (H1,...H4 and A1, A2, A3) to numeric index for the axis and I created manually cards to display the number of elements (which is also the size of each dot).

I would like something more convenient to update and easier to read for users. Does anyone know a solution to my problems ?

Thanks you

Stevan
