Dynamic Text Box to show exact equation

[shock]

I have created a variable equation like
y=ax^2 + bx +c
with a,b,c  taking the default value of  1.

so, i have the curve y=x^2 + x +1 being plotted on the graph.

the Status Bar shows
[  Equation 1: y=ax^2 + bx +c   ]

When i adjust the variable a,b,c using the constant controller,  the shape of the curve start to morph.  However, the status bar would not show the exact equation of the current curve.

For example, i have changed a= 1.5 and b = 2
the status bar still shows the same thing.  

Is it possible for me to have a dynamic text box showing the exact equation as i change the variables using the constant controller?

Appreciate any help on this.  Thanks

ok.  I sort of figured it out.

Just select the object.  Select "Text box" after right click.
That is easy.
