问题
In the old static image Google charts I have been producing a combined chart like this one:
It has 3 series (the bars drawn in dark green, light green and pink - on the top) and then it is overlayed by one more data serie - the blue line.
My question is: if that is possible in the new Google charts?

Looks like Combo Chart still has documentation for columns, stacked columns and lines.
