To set the axis lengths (in centimetres), use commands like `<font color="#82140F"><code>set x size 5</code></font>' and `<font color="#82140F"><code>set y size 7</code></font>'. Some people like the ratio of axes to be in the so-called golden ratio `<font color="#82140F"><code>(root(5)-1)/2</code></font>'; to get that, you could do this: <p> <TABLE SUMMARY="Example" BORDER="0" BGCOLOR="#efefef" WIDTH="100%"> <TR> <TD> <PRE> <font color="#82140F"> set x size 15 set y size {rpn ..xsize.. 5 0.5 power 1 - 2 / *} </font></PRE> </TD> </TR> </TABLE> <p> For maps, you'll want the plot scaled so that shapes retain their aspect ratio. To do this, do `<font color="#82140F"><code>set x size .cm.</code></font>' and then do `<font color="#82140F"><code>resize y for maps</code></font>' (or vice versa). <p> </table> <img src="./resources/bottom_banner.gif" usemap="#navigate_bottom" border="0"> </body> </html>
