Description
I am trying to recreate an example from the chart section of the documentation, specifically the one that draws a faded area under the line of the chart. Unfortunately, some of the functions used like lv_draw_task_get_type
, lv_draw_task_get_draw_dsc
, lv_chart_get_series_color
are reported as undefined and I can’t use them. Those 3 are the only functions missing for me from the entire linked example.
What MCU/Processor/Board and compiler are you using?
Windows simulator on Visual Studio 2019
What LVGL version are you using?
v9.1 as defined here:
#define LVGL_VERSION_MAJOR 9
#define LVGL_VERSION_MINOR 1
#define LVGL_VERSION_PATCH 1
#define LVGL_VERSION_INFO "dev"
What do you want to achieve?
I want to be able to use the functions mentioned in the description.
What have you tried so far?
Checked that both defines like “LV_USE_CHART” and “LV_USE_DRAW_SW” are set to 1.
I have also searched the lvgl
library folder but could not found the declarations and definitions of the said functions.
Code to reproduce
Just the basic code provided in this Chart (lv_chart) — LVGL documentation example
