Working with discontinuous data in Eureqa

Several features in Eureqa assume that your data is one continuous series of points by default, such as the smoothing features and numerical derivative operators. This post shows how to tell Eureqa that there are breaks in the data.

Entering discontinuity with a blank row:

To indicate a break in your data set, simply insert a blank row in the data spreadsheet. You can insert a blank row by right clicking on the first row of the next series of points. For example:

Eureqa will automatically recognize this blank line as a break between continuous series of data for each variable. This allows you to smooth the data correctly for data points between breaks. For example:

Without a break, the smooth would attempt to blur the two distinct series into a single smooth curve.
