Keep in mind that charts of this type are attractive but ineffective at
conveying information. They show very little data in a large area, the data
must be interpreted by estimating an angle (which human perception is not as
good at as estimating length of a bar or position of a point), they show
only one point in time (or multiple points but not along a time series), and
they are very easily misinterpreted. An effective business dashboard chart
is not a bunch of data mocked up to resemble a 747 cockpit.

Your data would be clearer and more concise plotted as line or column
charts.
