Hi,

For a custom order the easiest using lv_chart_set_ext_array.
See https://docs.lvgl.io/latest/en/html/widgets/chart.html#set-an-external-data-source

Yes I know this is an old thread–but it is what comes up in search results for “reverse chart direction”, so I figured I could add this for continuity: Chart Shift Direction - #4 by WebDust21

TLDR; modified the existing LVGL v8 chart data input function to just reverse the direction data where it’s inputted to the array. Very simple, and works a charm.
