11.10 The Intersect Gadget

Use the Intersect gadget to calculate the intersection points of the input curves in the ROI. This gadgt is available in the Gadgets menu when a graph window is active.

ROI Box

Shape Position	Specify the range on X direction using X1 and X2 values and the range on Y direction using Y1 and Y2 values.
Show Tool Name	Specify whether to show the tool name at the top of the rectangle in the graph. The tool name can be specified in Preferences.
Fill Color	Specify the color of the rectangle that attaches to the graph. See .

Options

Intersection Display

Specify how to display the intersection points.

Intersection Marker

Select to mark the intersection with symbols. Color, shape and size of symbols can be customized.

Intersection Label

Check this check box to add labels for the intersections.

Color	Specify the color of label text
Size	Specify the size of label text
Type	Indicate type of label (e.g., X, Y, or (X,Y))
Rotate(deg.)	Select the rotation degree of the labels in the drop-down list.
Digits	Customize the digits of the label. Default Decimal Digits: Display all digits for the intersection label (By default) Set Decimal Places = : The number of digits that display after the decimal place. Type the value in the associated text box. Significant Digits = : The number of digits displayed. Type the value in the associated text box.

After click Tag Points, the intersection labels are added on the graph. And RectIntersectMarker object item will be added in the (Show Graph Objects Mode ). Tag points multiple times will add multiple marker objects.
If you want to customize these labels, you can
- Double click on them to open the Maker Properties dialog.
or
- Right-click on the RectIntersectMarker in Object Manager and select Properties in the context menu to open the Maker Properties dialog.
Click and select arbitrary intersection label to dray can move the position for all intersection labels. If the labels are not tagged point at the same time, they will not be moved together. If you just want to move one label, you can press and hold the Ctrl key and click and select the label to move it.
Click and select arbitrary intersection label and select Delete in the context menu to delete these labels. Right-click on the RectIntersectMarker in Object Manager and select Delete also can delete the labels.

Interpolation Settings

Interpolation Method	Specify the interpolation method for the input curves. For more information about these three methods, please refer to the Help page.
Sampling Points	Specify the number of data points to interpolate.

Output To

Script Window	Check this box to output results to the Script Window.
Result Worksheet Name	Specify the output result worksheet: When you generate new output, results are output to [%H-Intersect]Result by default (here %H means the Short Name of source graph), but other books and sheets can be specified. If the book and sheet do not exist, they will be created on output. Alternately, you can click the flyout button to the right of Result Worksheet Name and choose Sheet in Input Book. This fills the edit box with [<input>]Result. When you generate new output, results are output to a sheet named Result in the source book.

Click the triangle button at the top right corner of the ROI tool to open the menu. Menu commands include:

New Output	Output results to the specified worksheet.
Go to Report Worksheet	Activate the report worksheet.
Output to Clipboard	When selected (menu item checked) New Output will be placed on the Clipboard.
Tag Points	Tag the found intersection points in the ROI.
Change Data	Change fitting data/plot. By default, all plots in current layer will be selected. Clear the check marks in front of All Plots to deselect all. Place a check mark in front of any plot to select that plot. Click Select... or More... to open the Select Plot(s) dialog.
