Code to reproduce

Add a code snippet which can run in the simulator. It should contain only the relevant code that compiles without errors when separated from your main code base.

The code block(s) should be formatted like:

    lv_obj_t * chart;
    chart = lv_chart_create(ui_bazal_screen);
    lv_obj_set_size(chart, 350, 50);
    lv_obj_set_y(chart, -50);
    lv_chart_set_type(chart, LV_CHART_TYPE_BAR);
    lv_chart_set_range(chart, LV_CHART_AXIS_PRIMARY_Y, 10, 100);
    lv_chart_set_point_count(chart, 24);
    lv_obj_set_style_bg_opa(chart, 0, LV_PART_MAIN | LV_STATE_DEFAULT);
    lv_obj_set_style_border_opa(chart, 0, LV_PART_MAIN | LV_STATE_DEFAULT);
    lv_chart_set_axis_tick(chart, LV_CHART_AXIS_PRIMARY_Y, 0, 0, 10, 1, true, 0);

Screenshot and/or video

If possible, add screenshots and/or videos about the current state.

I want to change the color of these

Can you tell me what I need to add?


It’s the lv_obj_set_style_line_color(chart, color, LV_PART_MAIN | LV_STATE_DEFAULT); property.
