Mixed from BarSeries and LineSeries

Can I make on one area to create a bar graph and a line graph, so that the line graph does not really matter indices (as in the example), but the values ​​(for example: the Count - Y and Date - X), but both graphics were dependent on one coordinate.
How I can do this?

I never got to do it with a bar-graph. I have used in place of a regular bar graph, line graph.
