Hi,
in line charts, if there is only one element in the series (I know it’s not a standard thing), the system crashes.
I solved it like this
In lv_chart.c in function:
static void draw_series_line(lv_obj_t * chart, const lv_area_t * series_area, const lv_area_t * clip_area)
add:
if ( ext->point_cnt > 1 ){ // check if the series consists of only one element
for(i = 0; i < ext->point_cnt; i++) {
Bye
