Uh oh! What happened here?
Did you know there are settings in your seating plan that determine the font size, as well as the height of the the rows and width of the columns?
In this case, the reason the row indicator letters can’t be read is that the font size is too big. To change any of those characteristics, go to Tools | Seating plans | <Highlight the seating plan> that you want to modify and click on the settings tab. See screen shot below:
Initially, the Chart font size was set to 16. Once we change it to 8, look what happens. The row indicator numbers are readable. This flexibility lets you customize how your chart looks.
