Bar chart with labels on series

Hi, is it possible to draw a bar chart with labels on top of each bar showing the current values?
I tried to modify the “Show cursor on the clicked point” example, but still with no success.
I guess it should somehow be possible by modifying the event_cb function, but since I’m new to LVGL I don’t have a clue yet. Can anyone help me, please?

Another question: Is it possible to change the color of each bar without defining multiple series?

I’m using LVGL 8.2.0 on an ESP32-3248S035 device via / vscode.
