title: Finding Points of Intersection In Excel Plots
body: <p>I have a scatterplot of experimentally obtained values and a line x=y, I wish to locate all points of intersection between the trend line and x=y, is there a method/function for doing so? </p>
  
  <p>There is no equation which approximates the trend line well enough to solve algebraically. </p>
  
  <p>Thank you for your help. </p>
