I have an intensity graph on which the y axis represents discrete channels. I want to be able to zoom the chart so that there are an integer number of channels displayed. The default behaviour seems to be that when you xoom, it is possible to see half channels on the plot. What I'd love to have is a situation where if the zoomed range on the Y axis was showing for example channel 22.7 to channel 28.1, that the plot would resize the Y axis to the range 23 to 28. I'd also want to be sure that a minimum of one channel were displayed. I see no obvious easy way of doing it, but I'd love to be wrong........
Thanks for any help,
Joe
