The lv_meter_set_indicator_value function allows for setting the value of an indicator on a meter object. This is useful for animating the indicator to a new position based on a new value. The LV_SLIDER_SYMMETRICAL option can be used to draw a symmetrical indicator, while LV_SLIDER_RANGE allows for setting a range of values. Additionally, the Line meter object can be used to create a vertical bar with color-coded scale lines based on the current value. LV_PART_MAIN and LV_PART_INDICATOR are used to customize the background and indicator respectively for a switch object. The LV_GAUGE_PART_MAJOR virtual part describes the major scale lines for a gauge. This functionality is part of the powerful building blocks provided by the framework, including buttons, charts, lists, sliders, and images.
