Notes on Drawing
If you specify a function that is undefined in some segments of X axis,
these segments will be draw in Red, as in this example:
let's say y=log(x+50) with a range specified of -100 < x < 100
As You kow, log is undefined for negative argument, i.e. x< -50.
You will get:
If you choose autocentering of axes, sometimes you will NOT see axes: this
is why axes are draw at x=0 and y = 0 and sometimes the origin will be
for example if you set y= logx with› 100 < x < 1000 x doesn't
encompass x=0 so the Y axes is not drawn; y ranges from log(100) that is
4.6 and log(100) that is 6.9 so y=0 is out and X axes will not be drawn.
If you plot on a Printer, You will be scaled accordingly, but read about
resolution in "Print Command" Note
