Subject: Drawing lines on a scatter plot
Hi,
I created a simple scatter plot of the log of sales (l_Sales) on the
vertical axis and the log of price (l_Price) on the horizontal. Now I
want to draw a vertical line and a horizontal line, both at their
respective means. I tried to edit the graph and add a line using the
Lines tab. I enter a formula such as mean(l_Price). But I got an
error: How can I add the lines? Any suggestions are appreciated.
Thanks,
Walt
