In variability gauge charts, the connected means lines default to a blue color. Is there any ways to make the default color black? I've looked through the Preferences window, and I'm only able to find how to do this in Fit Y by X graphs.
While I'm still interested in an answer, I've found a workaround. The default blue color was getting frustrating when I would make several variablility charts at once and had to go through each one individually to change the connected means lines color. I just noticed the copy/paste customizations feature. I can use this instead, and pressing Ctrl applies the setting to all graphics.
