Integral

Integral - Creates a new curve which represents an integral curve of the selected channel. The method is based on calculating Cubic Spline interpolation and an integral applied onto that interpolation resulting in a polynomial equation. For input parameters this method uses a number of points inserted between each and every two adjacent points. It is necessary to make a choice if you wish the integral to be calculated Node-to-Node or integral for the whole function. If you turn node to node option on, then the integral graph will have a saw tooth shape and the integral curve will start from zero in each point of the selected channel/curve. If this option is turned off, the integral curve is continuously growing, for positive functions and so this option makes sense only if the function is frequently changing its polarity.
