Complex Scatter Charts

Hi there :slight_smile:

I want to build a nice X-Y Chart, where working points are moving around fancy and the background is based on data, not pictures :smiley:

I’m currently using the LV_CHART_TYPE_SCATTER type and
adding points with the lv_chart_set_next_value2() function.

Here is a sneak peak how it looks at the moment:

  • So how can i get rid of those dots? → fixed: on draw event set points transparent
  • How can i fix the scale?
    I want to show numbers with more precision not integers on the scale.
  • How can i make longer lines? → fixed: lv_chart_set_point_count(chart, 11);
  • Also I want it to be more fancy, is there something like a spline function?
  • I want also want to add a dashed line

Thanks for Help,
Greetings Silvester

More questions to come :smiley:
