Scale (lv_scale)

Overview

Scale allows you to have a linear scale with ranges and sections with custom styling.

Parts and Styles

The scale widget is divided in the following three parts:

  • LV_PART_MAIN Main line. See blue line in the example image.

  • LV_PART_ITEMS Minor ticks. See red minor ticks in the example image.

  • LV_PART_INDICATOR Major ticks and its labels (if enabled). See pink labels and green major ticks in the example image.

Usage

Set ranges

The minor and major range (values of each tick) are configured with lv_scale_set_range(scale, minor_range, major_range).

Configure ticks

Set the number of total ticks with lv_scale_set_total_tick_count(scale, total_tick_count) and then configure the major tick being every Nth ticks with lv_scale_set_major_tick_every(scale, nth_tick).

Labels on major ticks can be configured with lv_scale_set_label_show(scale, show_label), set show_label to true if labels should be drawn, false to hide them. If instead of a numerical value in the major ticks a text is required they can be set with lv_scale_set_text_src(scale, custom_labels) using NULL as the last element, i.e. static char * custom_labels[3] = {"One", "Two", NULL};.

The length of the ticks can be configured with the length style property on the LV_PART_INDICATOR for major ticks and LV_PART_ITEMS for minor ticks, for example with local style: lv_obj_set_style_length(scale, 5, LV_PART_INDICATOR); for major ticks and lv_obj_set_style_length(scale, 5, LV_PART_ITEMS); for minor ticks.

Sections

A section is the space between a minor and a major range. They can be created with lv_scale_add_section(scale) and it handles back an lv_scale_section_t pointer.

The range of the section is configured with lv_scale_section_set_range(section, minor_range, major_range). The style of each of the three parts of the scale section can be set with lv_scale_section_set_style(section, PART, style_pointer), where PART can be LV_PART_MAIN, LV_PART_ITEMS or LV_PART_INDICATOR, style_pointer should point to a global or static lv_style_t variable.

For labels the following properties can be configured: lv_style_set_text_font(), lv_style_set_text_color(), lv_style_set_text_letter_space(), lv_style_set_text_opa().

For lines (main line, major and minor ticks) the following properties can be configured: lv_style_set_line_color(), lv_style_set_line_width().
