| Input

iy
|
Input
XYRange
|
<active>
|
Specify the input data to be integrated. Note that beginning with Origin 2020b, there is a shortened syntax that follows the form [Book]Sheet!(X,Y1:YN), X = the common X column and Y1:YN = a contiguous range of Y columns to the right of the X column. More complex strings from non-contiguous data of the form [Book]Sheet!((X,Y1:YN),(X,YM:YO)) are also possible.
|
| Use End Points Straight Line as Baseline
|
baseline
|
Input
int
|
0
|
Specify whether to create a straight line that crosses the end points and use it as the baseline for the integration.
|
| Area Type
|
type
|
Input
int
|
0
|
Specify the integral area type. Please see more details in the More Information part below.
Option list:
- math:Mathematical Area
- The area is the algebraic sum of trapezoids.
- abs:Absolute Area
- The area is sum of absolute trapezoid values.

| Plot Integral Curve
|
plot
|
Input
int
|
0
|
Specify whether to plot the integral curve, and where to plot the integral curve.
Option list:
- none:None
- Do not plot the integral curve.
- new:New Graph
- Plot the integral to a new graph.
- source:Source Graph

This X-Function performs integration on input data. It can calculate the Mathematical Area (the algebraic sum of trapezoids) or an Absolute Area (the sum of absolute trapezoid values). Missing values are ignored.
If you want to integrate data with the absolute area method and plot the integral curve, you can do the following:
