2 y axis, bar and line graph question

[Kyle]

I am plotting 2 series of data against time. One series
needs to be a line and the other a bar. I got it pretty
close with the 'custom types' (built in)-- 'line - column
on 2 axis'. However, this will only let me have the
primary y-axis as the bar graph. Is it possible to
customize this further so that the primary y-axis is the
line and the secondary y-axis is the bar graph?

Thanks, please help.
