Guidelines for interpreting correlation coefficient r :
  0.7<|r|≦1        strong correlation
  0.4<|r|<0.7     moderate correlation

Purpose of use
College project involving fitting curve to test data
This is a nice tool, but I''m not able to use it for my project because I can''t adjust the y-axis, nor the x-axis. I''m dealing with test data where 0<= y <= 5, and 1<=x<=99. The curve being generated for my test data is entirely useless since the y-axis goes up to 1400.

I would absolutely love this if I could adjust the scale.
