1) What combination of syntaxes or references is needed to change the y-axis scale at run time?
i think its object.plot.axis(y).... but i can't find the right one

2) Is there any event that detets when a user click on a certain section of the graph?
Ex. if you have a stacked bar graph, of two different items over a weeks span, is there any way to detect what row/column/series the user clicked on?

thanks in advance.
