Piecewise plot vertical line

Posted 10 years ago
Hi, I'm intending to plot a piecewise fuction. The horizontol lines displays correctly. 
How can I plot the vertical line connecting 20 and -60 @ x=6    and  -60to0 at X=8
 
 g[x_] := \[Piecewise] {
 
    {20, x < 6},
 
    {-60, 6 < x < 8},
 
    {0, True}
 
  }


Plot[g[x], {x, 0, 10}]

Plot[g[x], {x, 0, 10}, Exclusions -> None]

Just add the option to the plot: Exclusions -> None

You can try giving explicit Exclusions:

Plot[g[x], {x, 0, 10}, Exclusions -> {x == 6, x == 8}, 
 ExclusionsStyle -> Red]

On my system (Mma version 10) I get the vertical lines also with this:

Plot[g[x], {x, 0, 10}, ExclusionsStyle -> Red]

I tried this on Mathematica 8.0.4 on a Mac and it shows the same problem (missing vertical lines at x={60,80} also.

What version and OS did you have your problem and successes on?

Strange.
I tried the same code from a different machine and now it displays the verticle lines as expected.
