Subscript text in label

[Jernej Jerin]

Hello!

I have added the following code in my code:

var j = "d";
j = j.sub();

plot1 = $.plot($("#grafTemp"), [
{label: "Rosišče (°C): T" + j + "(t) = ---.---°C", .... the
rest does not matter

And:

legends.eq(i).text(series.label.replace(/=.*/, "= " + y.toFixed(2) +
"°C"));

I was using this example:
http://people.iola.dk/olau/flot/examples/tracking.html

Now, the subscript works ok, it displays T_d fine. But when I update
the graph (when user moves mouse over graph), then it displays <sub>d</
sub>. I know that the problem is at the legends.eq(i).text....., where
it returns pure string, with literal <sub>. I would like to know, how
it would be possible to fix this issue.
