The radius graph offers a 2D Graph view of the radius throughout an element.
This can help you determine if your element is having pumping issues or bumps at the control points.
Usually when your element has pumping or bumps in it, there is a simple reason.
There are 3 things to check if your element looks badly on this graph.
First, there may be too few plot-points.
Try increasing the number of divisions for your formula and re-plot it.
Second, the precision may be too high.
Remember that precision works backwards, larger values give worse results.
If the precision is set to 0.01, then try setting it to 0.001 and re-plot the formula.
Finally, there may not be enough segments.
Even though the formula can be limited to creating a certain number of segments, they may not fit the element very well.
An example of this would be trying to create a corkscrew with only 2 segments.
It's just not going to fit correctly.
Here is an example graph of an extremely smooth corkscrew element.
And by contrast, here is an example graph of a corkscrew full of pumping and bumps.
