Another question about my current macro. I am plotting:

.ChartType = xlXYScatterSmoothNoMarkers

How do I change the color of the line? Here's a sample of my data I'm plotting:
ActiveChart.SeriesCollection.NewSeries
ActiveChart.SeriesCollection(1).Name = Cells(1, 7)
Set CAF1X = Range(Cells(3, 7), Cells(SpecNum, 7))
Set CAF1Y = Range(Cells(3, 9), Cells(SpecNum, 9))
ActiveChart.SeriesCollection(1).XValues = CAF1X
ActiveChart.SeriesCollection(1).Values = CAF1Y
It's probably not the most efficient, but it works. Basically, I have a column of X, a column of Y, and this has worked for me to get the information into my chart. I want to have the ability to change the color away from the excel preset colors. Any help? I've tried all kinds of codes I've found online, but so far nothing has worked.
