### Re: TeX symbol as label in graph

Please note that in my question, $a denotes a scalar (which varies with seed), it is not intended to initiate LaTeX "math mode". I can display linear equations within the graph using Context("Numeric");$a = random(3,9,1);
$x="x";$ftex = "$a$x+1";

And then within the graph, provide:

$label4= new Label(3.2 , 2 ,$ftex,'black',('center','center'));
$graph1 -> lb($label4);

(improvements welcome!)

But can not figure out how to get a formatted LaTeX expression to appear (specifically one involving symbols or letters such as \theta).

Thanks.
