I can only get three grey regression line with the lsline command. Linear Regression Introduction. The list of markers is replicated so that you never run out of markers in case the dataset grows, though that would result in duplicate markers if the number of points exceeds 13. lsline superimposes a least-squares line on each scatter plot in the current axes.. lsline ignores data points that are connected with solid, dashed, or dash-dot lines ('-', '--', or '.-') because it does not consider them to be scatter plots.To produce scatter plots, use the MATLAB ® scatter and plot functions. | Stata FAQ.
