I have a figure where the range of x values starts at a negative value and goes to a positive value. I would like to "highlight" the vertical grid line at an x axis value of zero. By highlight I mean increase the width of that gridline or maybe even change the color. Changing the line from solid to dash might also be a good idea.

You can draw the lines using function line

There are a couple possible ways to do this. Off the top of my head the one I'd probably use is to set the YAxisLocation property of the axes to 'origin'. See the pictures in the documentation of that property on this documentation page. You could also create a line using the xline function.
