[scilab-Users] Drawing Y-axis in graph

[Prof. Dr. Reinaldo Golmia Dante]

wow .. good suggestion !! 
 
Samuel,
 
do you know why the Y-axis at x = 0 doesn't cover the range (y_inicial, y_final) ?
 
If you run the following scrip you will see that the Y-axis goes until 0.1 ! I have no idea !
 
function f=funcao(x) f = 2*x*exp(-x^2); endfunction x_inicial = -4; x_final = 4; n = 100; // number of points xdata = linspace ( x_inicial , x_final, n); for i = 1:n f1(i) = funcao(xdata(i)); end y_inicial = min(f1); y_final = max(f1); plot (xdata, funcao) xtitle ( "Função" , "X axis " , "Y axis " ); drawaxis(x=x_inicial:x_final,y=0,dir='d',tics='v'); //Here X-axis displays drawaxis(y=y_inicial:y_final,x=0,dir='r',tics='v'); // Here Y-axis displays legend ( "2*x*exp(-x^2)" );
 
 
Tnx
Reinaldo.

I would like to have both.

But you can also use grids instead:
xgrid(color("grey"))
This may be clear enough for students
