There are many `<font color="#82140F"><code>set</code></font>' commands, and they are all pretty simple, e.g. `<font color="#82140F"><code>set x size 15</code></font>' makes the x-axis be 15 centimeters long, instead of the default of 10 centimeters. Indeed, you can control anything you want in gri, e.g. graph size, line width, fonts, etc etc. Speaking of fonts, the `<font color="#82140F"><code>$\alpha$</code></font>' type of latex formatting of Greek letters is supported in a limited way. Also, Gri handles ISO-Latin-1 encodings as well as the U.S. style. <p> The example below illustrates a few more `<font color="#82140F"><code>set</code></font>' commands. This example is intentionally complicated, being about a good example of the level of complexity of many plots made by Gri. Read the comments to see what is being done, and consult the plot as you read the commandfile. <p> <A HREF="example3.png"> <IMG ALT="Example 3" SRC="example3-tiny.png" ALIGN=top> </A> <A HREF="example3.html">The command-file.</A> <P> </table> <img src="./resources/bottom_banner.gif" usemap="#navigate_bottom" border="0"> </body> </html>
