Description

What MCU/Processor/Board and compiler are you using?

zephyr/nrf52

What LVGL version are you using?

maybe 8.2

What do you want to achieve?

If the variable value in the chart is 0, I hope it will not be marked.
Now, it is indicated as a picture and is experiencing inconvenience.

What have you tried so far?

lv_chart_set_range (chart2, lv_chart_axis_primary_y, 0, 30);
I tried to raise the min, but it wasn’t what I wanted.

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_chart_set_range(chart2, LV_CHART_AXIS_PRIMARY_Y, 0, 30);
//
lv_chart_set_next_value(chart2, ser2, 0);
lv_chart_set_next_value(chart2, ser2, 10);

Screenshot and/or video

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

You can set that point’s value to LV_CHART_POINT_NONE.

Thank you for always. :+1:
I couldn’t find it in the documents. :sweat_smile:
When it is displayed as ui, it is displayed as -nan, but we will find a solution later.

Done worry, I also have a kind of “reading-blindness”. Especially when I need to read the texts I have written. :smiley:
