Great! Thanks Jeffrey! I didn't know about the existence of this option 'q w2xy lat lon' to find the virtual page coordinates!<br><br>Mireia<br><br><div class="gmail_quote">2011/9/15 Jeffrey Duda <span dir="ltr"><<a href="mailto:jdduda@iastate.edu">jdduda@iastate.edu</a>></span><br>
<blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">I'm assuming you know the lat/lon coordinates of the end points of the line representing the cross section. Use 'q w2xy lat lon' to determine where on the virtual page your lat/lon coordinates lie. Then take the output into some variable and use the <a href="http://www.iges.org/grads/gadoc/gradcomddrawline.html" target="_blank">draw line</a> command to draw the line on the page. If you are drawing with projected data, beware that the line you draw will probably be distorted due to the projection. But if you are using latlon for mproj, your line should appear correctly.<br>

Hi,<br><br>I am plotting arbitrry cross sections as explained in the grads documentation. Now, I would like to draw the lines through where I am doing the cross sections in a 2D lon-lat map.<br><br>Anyone knows how to do this?<br>
