Place a line as a marker in a 2D image

Hi everybody,

I would like to add colored lines (let's say red) to a 2D image i created with imagesc. I am going to analyse a certain colom of this image, and 1 would like to add colored vertical lines to the image, so I can show which lines have been analysed (to show in a report). I hope someone can help me with this.

Thanks! Ellen
