By default, lines come with a dark transparent fill, covering the area between the line and x-axis. Polar area charts are closely related to pie charts, with the difference that in addition to the angles representing the relative size of the data points, the radius of each element is set in relation to its value. This can be done fairly easily by maintaining a Queue of elements and sampling the delta value difference to it. This needed some code refactoring.

We also set the animationDuration to 200, this is needed so our gauge needle won't take too much time to interpolate between updates. While it is true it does not come out of the box, but with adjusting 2 pieces of codes it can become one. To produce the graph above, for example, we have four data objects: two set to bar, and two set to line, while the type for the Chart object is set to bar. Now, let's look at point 2 as we need to compute packets per second rate.
