Line (lv_line)
Overview
The Line object is capable of drawing straight lines between a set of points.
Parts and Styles
LV_PART_MAIN
uses all the typical background properties and line style properties.
Usage
Set points
The points have to be stored in an lv_point_t
array and passed to the object by the lv_line_set_points(lines, point_array, point_cnt)
function.
Auto-size
By default, the Line's width and height are set to LV_SIZE_CONTENT
. This means it will automatically set its size to fit all the points. If the size is set explicitly, parts on the line may not be visible.
Invert y
By default, the y == 0 point is in the top of the object. It might be counter-intuitive in some cases so the y coordinates can be inverted with lv_line_set_y_invert(line, true)
. In this case, y == 0 will be the bottom of the object.
y invert is disabled by default.
Events
