Analyze g Integrate

Calculates the sum of the area of the selected graph, which is the inverse of a differentiation. This function will calculate the area from the start of the plot until every data point. This way you end up with a plot, not just one area value. The last data point will contain the area of the whole graph this way. If you only need one value for the area of the whole plot (or a part of it), you can use the Area above X axis command.
