when i create a chart by lv_chart_create, but the lv_chart_set_axis_tick and lv_chart_set_zoom_x function is discard, how to replace? about lvgl HOT 8 CLOSED

Hey,

This example uses lv_scale as a chart axis. You should be able to achieve all of the same effects lv_scale. Let me know if you need any clarification or help achieving what you need.

We have a separate scale widget, because the scale-like behaviour is uses on a lot places. This way the scale can be used in a more flexible and modular way. For example you can make it scroll with the chart or make it fixed.

However I agree that some helper functions would be nice to make it easier to add the axis to the chart. (or at least some better example would be great) I can't immerse in now, so ideas are very welcome.

Yes，i agree to custom, but i thongt not all widgets that use the scale to custom，some helper functions would be nice to make it easier to add the axis to the chart。when to add them back?

I think the lv_chart_set_axis_tick and lv_chart_set_zoom_x is needed, if they could not achieve the effect, then i could use the scale, not all functions to custom.

others, the scale need to create a obj, then to create the scale, but when i use the lv_chart_set_axis_tick and lv_chart_set_zoom_x，it set to chart directly, not need to create the obj.

Perhaps we can bring those functions back. It must have been changed for a reason though. This is the commit that removed those functions and here are all the other changes that day, Oct 12, 2023. @kisvegabor, what's the history behind it?
