Suppose I have looped through N time series variables and have N slope coefficients from a simple regression for each dependent variable in a Nx1 matrix. I now want to show these as y variables in a scatter plot for a given x variable -- in a different (and already constructed) Nx1 matrix. Can I easily do this ? I tricked GRETL to plot 2 new series based on the matrices as so scalar nn=rows(bx) smpl 2001:01 2001:01+nn-1 series y= bx series x= mx chart1 <- gnuplot y x --with-lines But I'd rather not trick gretl by creating series, when the matrix values are not actually time series. I could export the matrices to a new dataset or export to another plotting package or even use EXCEL, but I wonder if there is something more elegant all in GRETL -- i.e. create a plot directly from the matrices, independent of the dataset design (ie. time series, cross section, panel) and current smpl period PS It took me some time to figure out I could only create the series y= bx if the smpl was the exact right size -- error message was a little obtuse. The error: 'The variable y is of type series' A error message such as 'Can not create series from matrix unless smpl period agrees with matrix size' would be bettter.
