How do you add more than one expression into the title of a chart. I have two cycle groups in my chart but the default setting is to only use the first expression label. I want to be able to make a chart title that uses a concatenation of the two cycle groups.
In the image below you can see that the chart title 9L cases comes from the cycle group. I want to make the title appear like the following:
"9L cases vs Total cases". To do this, i'd have to use values from both cycle groups but don't know how to do this.
