+The \verb+plotstyle+ option is defined in the package \verb+pst-plot+, but its value
+\verb+LSM+ (\textbf{L}east \textbf{S}quare \textbf{Method}) is only valid for the
+\verb+pstricks-add+ package. Instead of plotting the data records as dots or a line,
+the \verb+listplot+ macro calculates the values for a line $y=v\cdot x+u$ which fits
+best all data records.

+With \verb+PstDebug=1+ one gets the equation $y=v\cdot x+u$ printed, beginning at
+the position (0|-50pt). This cannot be changed, because it is only for some kind
+of debugging. Pay attention for the correct \verb+xStart+- and \verb+xEnd+-values,
+when you use the \verb+\pstScalePoints+-Macro. In the following example we use an
+x-interval from 0 to 3 to plot the values; first we substract 0.003 from all x-values
+and then scale them with 10000. This is not taken into account for the \verb+xStart+- 
+and \verb+xEnd+-values.
