Normal Circular Probabilities
Normal Probabilities / RV probabilities - You can make the Z - values equal also, that is a little more interesting - See picture at different settings.
1) adjust probabilities to equal each other - diagonal to each other - You can Make Line Length equal Normal Probabilities too.
2) See Z - values - Line Length + RV probabilities approximately = Z - values in a Range of [1-4] Green Slider - Bottom Line in Table
