Ray (Plot)

) plot to visualize the value of a ray variable versus time for all rays, or to plot two ray variables against each other at a set of time steps. The plot must point to a Ray (Data Set). Add a Color Expression subnode to color the resulting lines, or add a subnode to plot the properties of only a subset of rays in data set as needed. For the settings in the subnode, see Filter for Ray and Ray Trajectories. To add this plot type, right-click a node and choose from the menu.

	Go to Common Results Node Settings for links to information about these sections: Data, Title, Coloring and Style, and Legends. For Ray plots, only Ray data sets are allowed as inputs.

	This plot is available with the Ray Optics Module or the Acoustics Module.

In the section, you can define an expression, which may be dependent on both particle and field variables.

Select a : or .

For , a distinct line is plotted for every ray, with the y-axis being the user-defined expression from the section and the x-axis being time. The total number of lines equals the total number of rays (after taking the subnode and the selection of the Ray (Data Set), if any, into account) multiplied by the total number of selected outer solutions if applicable.

For , the expressions entered in the and sections are plotted against each other for all rays at each specified time — that is, the total number of lines equals the total number of selected times multiplied by the total number of selected outer solutions.

Select the check box to display the plotted expressions to the right of the plot. In plots where each line represents a certain time value, eigenvalue, or parameter value, these values are also displayed.

When is selected from the list (the default), the legend texts appear automatically. If is selected from the list, enter your own legend text into the table.

Choose an : (the default), , , , , , , or . The Operation is applied to the rays only if the x-axis is . If is selected, a distinct line is plotted for each ray, otherwise the selected data series operation is used to compute a single data point for all rays at each time step. The default prevents an extremely large number of lines from being plotted when a new Ray plot is created.
