Stack Line Plots: fix typo
Purpose: The stack line plot enables to make line plots over a complete stack of images.
How To: The line can be either straight, freehand or segmented and needs to be drawn beforehand. If the input image is a hyperstack the user can choose to plot
oover the z-slice or the t-frame range. In such a case the intensities of the active channel are taken for the plot. The macro automatically creates a stack of plots along the line selection with the upper intensity limit set at the highest intensity occuring along the line over all images. If the [Shift] key is held down before and while going to >BioVoxxel Icon >Stack Line Plots the limit is set to 255 for 8-bit images and 65535 for 16-bit images
