sorry but i cant see the time at large value of x e y. can you put the time in the middle of screen?

slider y must reach 1500 (positive value), because x or y = 1 = 100um yet

so I have to be able to read on the screen y = 1500 y = -1500

the value of sigma must reach 300 from 0.01

then the view of the Gaussian function could be enlarged with the increase of the work area?

thanks
