I need to plot a vertical line in a figure with log y-axis:
semilogy([34,34],[0,22222]);
But the figure does not show the vertical line.
For horizontal line,
semilogy([34,66],[22222,22222]);
This command works and shows an horizontal line.
Can anyone help me, thanks in advance.

For the non-log plot, I can plot the vertical line using "plot" or "line" command, but if I hold on and make y-axis in log, then these vertical line disappeared.

I got it. I cannot use zero in log plot, use 0.00000001 or so instead.
