Hi, I would like to add a trend line to a scatter chart. It needs to look something like this...
http://en.wikipedia.org/wiki/File:Linear_regression.png Anyone have any luck with this? One way of doing it would be to have three columns, Xs, Ys of Data, and Ys of trend line. But the problem I have is that you can't control the line size of indiviual columns. If you could, like the way you can do with color, it would be possible to turn off the line for the scatter data, and turn on line for the trend line. But now if you want the trend line to show up you also have a messy line connecting all of the scatter points. Any suggestions would be a great help. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google Visualization API" group.
