Then the tool performs integration on the chosen section to calculate the area under the curve and display the results instantly on top of the ROI. With this Gadget, you can: Specify the integration limits Specify baseline https://www.originlab.com/doc/Origin-Help/Gadget-Integration 1/9 9/11/2019 Help Online - Origin Help - The Integrate Gadget Display the difference curve and the integral curve inside the ROI Calculate quantities including: peak area, peak height, peak center and FWHMSearch To Open Integrate Gadget To use this tool, select Gadgets: Integrate... from the Origin menu when a graph window is active. If the tool has already been activated, you can re-open the Integrate dialog by clicking on the arrow in the upper-right corner of the ROI and choosing Preferences. To Show or Hide Gadget Tool To toggle the display of all gadget ROI boxes in a graph at the same time, click the H button in the top right corner of the graph, which enables users to export the graph with gadget results. ROI Box tab Specify the X Data range for the ROI. From The beginning of X scale. X Scale To The ending of X scale. Fixed (Prevent moving by ROI) Fix the X scale to prevent from moving by ROI box. Show Tool Name (toolname) Fill Color (rectcolor) Show Area/FWHM on Center-Top (showtop) Specify whether to show the tool name at the top of the rectangle in the graph. The tool name can be specified in Preferences. Specify the color of the rectangle that attaches to the graph. See the list of colors.

Integration tab https://www.originlab.com/doc/Origin-Help/Gadget-Integration 2/9 9/11/2019 Help Online - Origin Help - The Integrate Gadget Specify the integration limits. You can get the limits through linear interpolation/extrapolation or use raw Search data points as integral limits. Interpolate to Rectangle Edge Fit Limits To (fitlimit) Specify whether to interpolate the two points at the rectangle edges according to the source data, and then use these two points as integration limits. Please note that if the rectangle edge exceeds the source data, it will not interpolate. Interpolate/Extrapolate to Rectangle Edge Specify whether to interpolate/extrapolate the two points at the rectangle edges according to the source data and then use these two points as integration limits. Data Points Do not interpolate and use the raw data points as integration limits. Specify the integral area type. Mathematical Area Area Type (areatype) The area is the algebraic sum of trapezoids. Absolute Area The area is the sum of absolute trapezoid values. Baseline Subtracted Curve Specify whether to show the baseline subtracted curve in the graph. Show Integrated Area Specify whether to show the integrated area in the graph. Keep the shading color after New Output Specify whether to keep the shadow of integrated area after selecting New Output options everytime. Note: For information on customizing the shaded (integrated) area and baseline, see this FAQ. Show (showIntegrArea) Integral Curve None Do not show the integral curve in the graph. Restrict to Rectangle Show the integral curve inside the rectangle. If the integral values are much larger than the original curve, the integral curve will be rescaled to restrict inside the rectangle box. The integral curve does not show the true values in this case. True Value Show the actual integral values in the graph. https://www.originlab.com/doc/Origin-Help/Gadget-Integration 3/9 9/11/2019 Help Online - Origin Help - The Integrate Gadget Baseline Tab Search Specify a baseline mode. None (Y=0) Use Y=0 as baseline. Constant Y Use a horizontal line as the baseline. Straight Line Method (method) Use a straight line, which can be tilted, as the baseline. Use Existing Dataset Use an existing data set as the baseline. 2nd Derivative Use the 2nd Derivative method to create baseline. End Point Weighted Create a smoothed curve using data points from two ends Y= (yvalue) This is only available when Constant Y is selected for Method. You can use it to specify the Y value for the horizontal line to be used as the baseline. This is only available when Straight Line is selected for Method. It works together with Y offset of left (yoffsetleft) and Y Offset of Right (yoffsetright). It is used to specify how to choose X values for the beginning and end of the baseline. Now, suppose we define the value of Y offset of left (yoffsetleft) as b1 and Y offset of right (yoffsetright) as b2; the beginning Y value of the baseline as a1, and the ending Y value as a2. Then we always have a1-b1=y1 and a2-b2=y2, where y1 and y2 are the Y values at x1 and x2, respectively. For how to define x1 and x2, see below. Entire Data Fix x to (fixxto) Fix x to the entire data set. When you select this, x1 is the X value of the beginning of the raw data and x2 is the X value of the end of the raw data. Rectangle Fix x to the rectangle. When you select this, x1 is the X value that corresponds to the left edge of the rectangle and x2 is the X value that corresponds to the right edge. Scale Fix x to the X scale. When you select this, x1 is the beginning of the scale and x2 is the end of it. Y Offset of Left (yoffsetleft) This is only available when Straight Line is selected for Method. It used to set the value of b1 mentioned above. Y offset of Right (yoffsetright) This is only available when Straight Line is selected for Method. It used to set the value of b2 mentioned above. https://www.originlab.com/doc/Origin-Help/Gadget-Integration 4/9 9/11/2019 Help Online - Origin Help - The Integrate Gadget This is only available when Dataset is selected for Method.

It specifies the polynomial order (1 through 9). Maximum Anchor Points Connected Method End Points(%) Specify the maximum of baseline anchor points. This option is only available when you set Mode to 2nd Derivative. Specify connect method for the anchor points. This option is only available when you set Mode to 2nd Derivative. Specify the percentage of end points to create baseline. This option is only available when you set Mode as End Points Weighted.

By default, the Auto mode will be checked in the fly-out menu, which means the target data/plot will follow the data plot selection/highlighting outside the ROI box on the graph. For the earlier versions Change Data than Origin 2019, Origin doesn't support this auto behavior; to change target plot/data, you can only select desired one from the fly-out plot list. In the flyout menu, it will show first 20 datasets/plots. If there are more than 20 plots in the graph, you can click More... at the bottom of the list to open the Select Plot dialog to select other plots. Expand to Full Plot(s) Range Fix ROI Position Expand the ROI box to the full Plots range. Fix the position of ROI box. Save Theme Save the settings in this dialog as a dialog theme.
