Hello, I'm trying to use 2 Y axes in a line graph and its not working, I have the date as the 'X' axis. I did a content analysis on newspapers and want to compare article sources with article image themes on the same graph. They are both different categories. Using the chart builder tool I selected the 2 Y axis option under the basic elements tab then tried to drag the categories to them but they refuse to go into the chart builder. I have no idea why. The measures are all nominal because the values in each category have no relation to each other.
Any help with this would be really appreciated, I an submit more information if I haven't provided enough
