Hi! I got this plot from converting from a ".numbers" file into a ".xlsx" file since I moved to Windows 10. My problem is that the charts I have seem to have a -0.5 shift for the vertical axis cross. I've tried manually setting this to 0.0, but it didn't work. (see Figures 1 and 2)
What I had to do to work is to create a new plot for this, which seems to have the correct axis (see Figure 3). I want to know what could have gone wrong here, since I don't want to re-do all my graphs (plot of 1000+ data points) and also Excel currently does not support multi-chart editing for Axis options, so I'd have to manually change all 10+ charts that I have.

Figure 1. Chart with Vertical Axis Cross set to 0.00, but is at -0.50

Figure 2. Chart with Vertical Axis Cross set to 0.50, but is at 0.00

Figure 3. New Chart with Vertical Axis Cross set to 0.00, and is correctly at 0.00
