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.<br>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 ?<br>

<br>I tricked <span class="il">GRETL</span> to plot 2 new series based on the matrices as so<br><br>scalar nn=rows(bx)<br>smpl 2001:01 2001:01+nn-1<br>series y= bx<br>series x= mx<br>chart1 &lt;- gnuplot y x --with-lines<br>

<br>But I&#39;d rather not trick gretl by creating series, when the matrix values are not actually time series.  <br>
<br>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 <span class="il">GRETL</span> <br>-- i.e. create a plot 
directly from the matrices, independent of the dataset design (ie. time 
series, cross section, panel) and current smpl period<br><br>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:    &#39;The variable y is of type series&#39;<br>A error message such as &#39;Can not create series from matrix unless smpl period agrees with matrix size&#39; would be bettter.  <br><br clear="all"><br>
