The chart I'm trying to set up, not the one posted here, shows five domains while "My Custom Charts" --> "Chart Contains" lists nine domains. Would I need to delete it and add them all at the same time to get them all to show up? Can new domains be added after the chart starts showing results? Is there a max to the number of domains that can be in the chart? I'm trying to make a chart for the Redscowl Bluesingsky Google contest, and then the v7n contest when it starts to make a chart like the one you made from the Nigritude Ultramarine contest....
You don't need to delete anything. If a domain isn't showing then most likely there is nothing to plot (you would need two points to plot for a line). There are no limits on the number of domains you can run on a single chart.
