How to draw a curve graph with chart?

How-to

Hi gabor,
I know LVGL doesn’t supprt it from https://forum.lvgl.io/t/the-enhanced-function-of-chart/376 so far.
I want to implement it in the branch, I will find the source code for line-chart and understand it, and then implement curve-chart based on it. But i don’t know where is the source code exactly for drawing line-chart …?

This is the part of the code that draws the lines, as far as I know: https://github.com/lvgl/lvgl/blob/f4b4df8a17a86463dc11ac38cd456d218c4e2196/src/lv_widgets/lv_chart.c#L910-L1056
