I am using two bottons, one for my analog tags and another for my digital tags, these bottons are configured to show and separate analog and digital signal in two subplot. The problem with the tag colors in the easy chart. When i drag a tag into the botton (analog or digital) the color of tags not changed and when i drag into the easy chart pens the colors changed. I don’t know what made to changed) any color of tags when i drag those into the bottons. I leave a reference picture.
If I understand correctly, you have code in the analog and digital buttons that adds tags dropped onto them into the Easy Chart. You'll want to add something to that code to set pen colors. See this post for an example:
