i have no clue how to start this application process i am working on. basically say the user chooses channel 1 of the 20 channels in a list - i want it to plot the whole channel in the first half of the form. Here the user can (with the help of line cursors) choose the start and the end point of the plot and the lower half of the form will show that much of the chosen graph. Is this even possible to do or am i trying something impossible?

Thanks ~svn
