The Graph Marker subnode () adds markers such as minimum and maximum values to Global, Point Graph, Table Graph, Radiation Pattern, and Octave Band plots. In the Model Builder, add and define a 1D Global, Line Graph, Point Graph, Radiation Pattern, or Octave Band plot; then right-click the plot node and select Graph Marker.

When you click the Plot button (), in addition to the graph marker in the Graphics window, a table is added with numerical values for, for example, Maximum and Minimum Values or Cutoff Points, for frequency-domain simulations, showing the frequency, coordinate, bandwidth, Q-factor, and damping ratio.

From the Display mode list, choose Min and max (the default) to display minimum and maximum values, Width to display a bandwidth for S-parameter analyses, for example, or Line intersection to add markers at intersections between the plotted curves and straight lines.

If you chose Min and max, from the Display list choose Min and max (the default), Min, or Max to display both the minimum and maximum or only the minimum or maximum. Additionally, choose Global (the default) or Local from the Scope list. The Local scope indicates the local extrema.

If you chose Width, from the Range type list choose Width (to specify a passband, for example) or Width outside (to specify a stopband, for example). For Width, choose Global (the default) or Local from the Scope list. For Local, it shows the width (passband) of each lobe or region relative to its local maximum. From the Cutoff mode list, choose Offset from peak (the default) or Relative to peak. Specify the Cutoff value (default: −3) if you chose Offset from peak. That value would represent a cutoff at 3dB below the maximum value in an S-parameter plot using dB scale, for example. Specify a Cutoff ratio (default: 1/) if you chose Relative to peak to make the cutoff value relative to the peak value. Also, if the scope is Global, you can choose Absolute from the Cutoff model list to specify an absolute cutoff in the Cutoff value field.

Note that if the data used in the graph to which the Graph Marker subnode has been added comes from a frequency-domain simulation, you can instead choose Bandwidth from the Display mode list. Also, you can instead choose Passband (the default) or Stopband from the Range type list. For Passband, choose Global (the default) or Local from the Scope list. See above for the remaining settings, which are identical to the ones for other data as described in the previous section.

If you chose Line intersection, from the Line type list, choose Vertical (the default), Horizontal, Identity line, or General:

To display the lines and not just their intersections, select the Show lines check box.

Enter a Display precision for the number of decimals displayed in the labels. The default is 6.

If the Display mode is set to Min and max, select the Show x-coordinate and Show y-coordinate check boxes to include the x- and y-position, respectively, of the marker (its space coordinates) before the maximum and minimum values.

Select the Include unit check box 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 values, add them in the Prefix and Suffix fields. The same prefix and suffix are used for the labels.

The Show point check point is selected by default to show the points for the minimum and maximum values. If desired, and if the Show point check box 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 check box to display the maximum and minimum values in a rectangular frame. Select the frame background color from the Background color list.
