The Polar Area Chart, like the Pie Chart and Doughnut Chart, presents content in a circular fashion. The Polar Area Chart is different however in that it does have a single axis that radiates from zero (at the center) to the maximum value on the grid at the perimeter. Each field is represented on the circular grid as an element where the further it emanates from the center, the large a value it represents. In the image below, twelve months of a year’s worth of sales are presented in the form of a Polar Area Chart.
As is the case with the other chart views in Ninox, segments can be toggled on and off from view by clicking on their representative icon in the Legend. The image below shows only those months in the second half of the same year of sales as is illustrated above.
It is important to know that the span of each segment, at their widest point (the point furthest away from the center) represents that segment’s value relative to the other segments. Or to look at it another way, if one were to draw a single circle around the outer edge of all of the elements in a Polar Area Chart, one would be left with a Pie Chart.
Hovering the mouse over any single element in the chart will result in the numeric value represented by that segment, along with the name of the segment appear in an on-screen help window.
