For the marker frequency, use two series. One plots the line connecting
all the points, but no markers. The other plots every Nth point.
The problem with dashed lines is that the sequence of line-gap-line is
started again at each data point. Someone posted a technique a while ago
which drew a shape consisting of a jagged line connecting the XY points.
When this line is formatted with dashes, each dash extends around the
corner past another point, so it looks like a dashed line in its
entirety. You could hunt in the google groups archive for it:

The exploded 3D pie charts are fine for the marketing types using Excel,
but as an engineer, you sometimes have to make your own tools.
Fortunately, despite some limitations, Excel is also flexible enough to
allow all kind of custom effects, like the dashed line I cited above.
