I would like to use Highcharts' Spline curve to estimate missing values on the x-axis. For example, I have y-values that I plot for x-axis values of 1, 2, 4, 5, and 6 (3 is missing). When I plot those using a Spline Series, I would like to read back the y-value of the Spline curve at x-value 3 (the missing x-value), as an estimate of the unknown y-value for x-value 3. But there is no Point at x-value 3, so how can I get the Spline curve's y-value at that x-location?
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
