In this article, we will see how to change the color of the line chart in R Programming In this example, we will be drawing five multiple lines with the different data and different colors of the line on a simple ggplot using the geom_line function from the ggplot2 package in the R programming language. See scale_fill_ramp() for examples. . Well plot both ‘psavert’ and ‘uempmed’ on the same line chart. I'm currently struggling to wrap my head around the following objective: a 2x2 facet grid; in each facet a couple of lines So now the line goes back-and-forth instead of starting and ending at the same position consistently, creating the following graph: Nonetheless, I assume there's a more universal way to handle this. setting color of line in ggplot2.
