How to plot an integral on Prime?

[TheKaneB]

Update:

on the 50g I've found a way to plot the function I want:
y(x) = INTVX(f(x)) - INT(f(x), x, 0)

Example: on the TI-89 I plot: ( I will use $ for the integral symbol)
y(x) = $(ln(x), x, 0, x)

and on the 50g:
y(x) = INTVX(LN(x)) - INT(LN(x), x, 0)

On the 50g the function entry is quite tedious, BUT it's many times faster than the TI. While the TI has drawn the first 2 pixels, the 50g has already finished the whole graph 3 times in a row

But still no luck on the Prime
Honestly, I'm getting tired of this calculator... If I can't solve this issue I'll stick to my 50g for everything
