Marker
The Marker subnode () adds maximum and minimum markers as well as markers at specified points. You can add it to several plot types, including 3D Volume, 2D and 3D Surface, and 2D and 3D Line plots. In the Model Builder, add one of those plot types; then right-click the plot node and select Marker. Contrary to adding a Max/Min Line, Max/Min Surface, or Max/Min Volume plot to the plot group, the Marker subnode does not perform any evaluations to generate its data — it uses the data generated by the parent Line, Surface, or Volume plot.
When you click the Marker Point button in the Graphics Interaction section of a plot group contextual toolbar, you can click in a 2D Surface, 3D Volume, or 2D or 3D Line plot to add markers. The markers are added to an existing Marker subnode where Point evaluation has been selected for the display or to a new Marker subnode.
Click the Plot () button at the top of the Settings window when needed to update the markers in the plot.
Display
Select an option from the Display list to determine what to display: Min and max (the default), Min, Max, or Point evaluation. If you choose Point evaluation, then add the coordinates for the points where to evaluate the expression and add markers to display those values in that table underneath the Display list. Use the Move Up (), Move Down (), and Delete () buttons underneath the table as needed. In addition, use the Clear Table button () to clear the entire table. Additionally, the Save to File button () saves the point coordinates to a text file (or to a Microsoft Excel Workbook spreadsheet if the license includes LiveLink™ for Excel®) for reuse in other models. The information is saved in space-separated columns in the same order as displayed on screen. When saving to Excel, an Excel Save dialog appears where you can specify the sheet and range and whether to overwrite existing data, include a header, or use a separate column for units. Using the Load from File button (), you can import or load data in text files created, for example, by a spreadsheet program. You can also click the downward arrow beside the Load from File button and choose Load From () to open the fullscreen Select File window.
Text Format
In this section, you can control the text format for the markers.
Select the Prepend the position checkbox to include the position of the marker (its space coordinates) before the maximum and minimum values.
Select the Include unit checkbox to add the unit of the expression for which the plot shows the maximum or minimum value.
If you want to add a prefix or a suffix to the labels for the minimum and maximum values, add them in the Prefix and Suffix fields. The same prefix and suffix are used for the minimum and maximum labels.
From the Number format list, choose one of the following formats:
•
 Default: Numerical values that come from the solvers are presented as-is. Numbers formatted during postprocessing use the Output display precision preference setting.
•
 Automatic: All numbers are formatted using the specified precision that you enter in the Precision field (default: 6). Select the Show trailing zeros checkbox if you what to display trailing zeros.
•
 Engineering: All numbers are formatted using engineering notation (such as 31.416E-6; it is similar to scientific notation but with the powers of ten as multiples of three) using the specified precision that you enter in the Precision field (default: 6). Select the Show trailing zeros checkbox if you what to display trailing zeros.
•
 Scientific: All numbers are formatted using scientific notation (such as 3.1416E-5) using the specified precision that you enter in the Precision field (default: 6). Select the Show trailing zeros checkbox if you what to display trailing zeros.
•
 Stopwatch: All numbers are formatted in decimal notation with a specified number of integer digits and decimals, which you enter in the Number of integer digits field (default: 3) and Number of decimals field (default: 2), respectively. Unnecessary zeros are always shown. For example, with the default settings, 17.1 would be formatted as 017.10. The specified number of integer digits is not respected if the number is too large or if it is NaN or Inf. Select the Always show the sign checkbox to keep the width from changing for a sequence that includes both positive and negative values.
•
 Scientific stopwatch: All numbers are formatted in scientific notation with one integer digit and a specified number of decimals and exponent digits. For example, with the default settings, 17.1 would be formatted as 1.71E1. The settings are the same as for the Stopwatch format, with the addition of an Always show the sign of the exponent checkbox. Select it to keep the width from changing for a sequence that includes both positive and negative exponents.
If you have selected the Prepend the position checkbox, you can choose a format for the position from the Position number format list, which then becomes available. See the Number format list above for information about the available options.
Coloring and Style
The Show point checkbox is selected by default to show the points for the minimum and maximum values. If desired, and if the Show point checkbox is selected, change the value in the Point radius field (default: 2) to a value between 0 and 1 to adjust the point size.
From the Color list, choose the color to use for the maximum and minimum values; choose From theme (the default) to use the color from the current color theme; or choose Custom to choose a custom color from a color palette.
From the Background color list, choose a background color for a rectangular area around the displayed maximum and minimum values; the default is None, which means that there is no background color. Choose From theme to use a background color that changes with the selected color theme.
From the Anchor point list, choose the position of the anchor point relative to the displayed values: Upper right, Upper middle, Upper left (the default), Middle right, Center, Middle left, Lower right, Lower middle, or Lower left.
From the Orientation list, choose Horizontal (the default) or Vertical, if you want the values to be displayed vertically instead of horizontally.
Select the Show frame checkbox to display the maximum and minimum values in a rectangular frame. Select the frame background color from the Background color list.
