Table Surface

) plot to visualize the data in a table that represents a matrix of values that are functions of two independent parameters (for example, as a response surface plot). See Creating a Surface Plot of Values as Functions of Two Parameters below. Right-click a to add this plot type from the submenu. This plot is also available by selecting (

) from the window’s toolbar.

	When created from the Table window toolbar, the 2D plot group with the Table Surface plot uses None in the Data set selection. When you add a Table Surface plot to an existing or new 2D plot group, the data set is typically a solution data set, and the plot group includes a plot of the data set edges. This can make the table surface plot hard to see because it uses parameter values on the x- and y-axis and not the 2D geometry’s dimension.

Creating a Surface Plot of Values as Functions of Two Parameters

Follow these steps to create a surface plot of values of some quantity as a function of two parameters, where you vary two parameters in a parametric sweep while keeping the other parameters fixed:

In the branch, add a (

) node.

In the window for , add the parameters that you want to sweep to the parameter list.

Select from the list to get a full parametric sweep of all parameter values.

Solve the model.

Add a (

) node under , select a point where you want to evaluate the solution data, and click . A table is created.

In the window, click the (

) button.

In the , select the node. In its window you can select which parameter to plot on the x-axis and on the y-axis, and which values you want to select as fixed for the other parameters.

Data

Select a with the data that you want to plot as a surface plot.

From the list, select one of the following formats for interpreting the table data:

•

Select if the data is structurally filled. See Filled Data for additional settings for this data format.

•

Select if you want to specify what columns to take the data from. See Columns for additional settings for this format.

•

Select to treat the tables data as cells in a matrix and use the table row and column numbers as the x- and y-coordinates, respectively. There are no additional settings for this format.

Filled Data

Select an option from the list: (the default) or . If is selected, select options from the and lists, which contain the parameters that define the rows and columns for the table’s matrix data, and from the list, which corresponds to the list in the node for the matrix data. If there are additional parameters in a parametric sweep, they need to be kept at fixed values, which you select from the list, which contains all combinations of parameter values for the parameters that are not used as x-axis or y-axis data.

Columns

From the , y-axis column, and Data column lists, choose the columns to use for the x-axis, y-axis, and the data, respectively.

For all data formats, select the check box if you want to plot the imaginary part of complex-valued data. For real-valued data, that plot shows a zero imaginary part.

Preprocessing

This section contains settings to preprocess the data in the table surface plot by scaling and shifting the data values, which can be useful to match data from different sources or to scale some data to express the values in another unit.

Under , , and , from the list select:

•

(the default), for no preprocessing of the data.

•

, to preprocess the data using a linear transformation of the data values for the x- or y-axis column or the data column. You define the linear preprocessing with values for the scaling (default: 1) and the shift or offset (default: 0) in the and fields, respectively. The default values do not change the original data values.
