Use an Annotation plot () to add an annotation anywhere in a plot. You can add Annotation subnodes to any plot group by right-clicking the plot group node and selecting Annotation. Add a Deformation subnode if desired. If you want to use a Deformation subnode to move the annotation in accordance with some other deformed plot, typically, select the Allow evaluation of expressions check box so that you can use expressions to define the deformation vector and select the other plot in the Inherit Style section to inherit the plot style from the plot that you want the annotation to move in accordance with.

This section is only available for an Annotation node under a 1D Plot Group that use two y-axes. In that case, select the Plot on secondary y-axis check box to plot the annotation using the coordinates for the secondary y-axis. You can also specify the axis to use in the Plot Settings section in the settings for the 1D Plot Group node.

In the Text field, type the text that you want to display as an annotation. If you want the annotation to also contain the position (displayed before the annotation text), select the Prepend the position check box.

If you want to include the value of some expression in the annotation, select the Allow evaluation of expressions check box. You can then type, for example, eval(T) to evaluate the temperature T in the annotation position, or eval(t,min) to evaluate the time t (in minutes). From the Geometry level list, you can select the geometry level fort the evaluation: Take from dataset (the default), Volume (3D only), Surface, Line, Point, or Global. Click the Replace Expression () or Insert Expression () button to select predefined expressions to use inside of the eval statement.

In the x, y, and z fields (for a 3D model with Cartesian coordinates; coordinate names can vary), enter the positions of the annotation as space-separated coordinate values. If you want to evaluate an expression that is defined in the geometry, the positions must be within the geometry. Click the Range () button to define a range of values for a coordinate. Click the Replace Expression () button to select predefined expressions to use as positions of the annotation. For example, if you have added a Mass Properties node and created variables for the center of mass, you can choose them to place the annotation at the center of mass.

In the Position precision field, enter the number of digits for the display of the position in the annotation (default: 6).

In the Expression precision field, enter the number of digits for the display of numerical values in the annotation (default: 6).

The Recover default is Off because recovery takes processing time. To use polynomial-preserving recovery and recover fields with derivatives such as stresses or fluxes with a higher theoretical convergence than smoothing, from the Recover list, select Within domains to perform recovery inside domains or Everywhere to apply recovery to all domain boundaries.

Select the LaTeX markup check box if you want to include mathematical symbols and Greek letters, for example, in the annotation. To include such symbols, surround the LaTeX syntax with $ to indicate that the text inside of the $ signs is LaTeX. For example, $\alpha = \beta/\pi$ appears as α = β/π. If the LaTeX markup check box is selected, you can also add line breaks as \\. See Mathematical Symbols and Special Characters for more information about available LaTeX symbols and characters (of which most but not all are applicable in this context).

Clear the Show point check box if you do not want to include a point in the plot at the location of the annotation.

From the Color list, choose the color to use for the annotation text; 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. Select the frame background color from the Background color list. 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 annotation text: 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 annotation text to be displayed vertically instead of horizontally.

Select the Show frame check box to display the annotation in a rectangular frame.
