Different coloured lines

[[Deleted]]

Hey, I'm trying to plot a custom ADX line that plots a different coloured ADX line based on DI+ > DI- or vice versa. For some reason it wont change the colour when plotting on chart, could someone give me an example on how to do that? thank you for your time.

Different colored lines can have various meanings depending on the context in which they are used. Here are some possible examples:

1. In charts and graphs, different colored lines or bars may represent different data sets or categories. For example, in a line graph showing the sales performance of several products over time, each product could be represented by a different colored line.

2. In road maps and transportation systems, different colored lines may indicate different routes or modes of transportation. For example, a subway map may use different colored lines to represent different subway lines.
