Here is a black & white plot since it was used for print publishing (in a presentation, color would be much better). We decided to invert the background since it separates the plot clearer from its surroundings in a paper.
The one possibly surprising feature is that there is no legend. In fact, if possible avoid a legend and put the description right into the plot. Think about how long it takes to parse the connection between lines and legend. Eyes go back and forth and back and forth …..
As done here it is immediate.
