Adding Datasets

Datasets are collections of plotted data points that can be extrapolated into an equation based on the piecewise linear makeup of the plot. Each plot consists of straight line segments whose vertices represent their end points. A curve is fitted to the segments of the plot and an expression is derived from the curve that best fits the segmented plot. The created expression is then used in piecewise linear intrinsic functions.

 

Adding a Dataset

1. On the Project menu, click Datasets.

The Datasets dialog box appears.

2. Click Add.

The Add Dataset dialog box appears.

3. Optionally, type a name other than the default for the dataset in the Name text box.

4. Type the x- and y-coordinates for the first data point in the row labeled 1.

5. Type the x- and y-coordinates for the remaining data points in the dataset using the same method.

After you type a point’s coordinates and move to the next row, the point is added to the plot, adjusting the view with each newly entered point.

6. When you are finished entering the data point coordinates, click OK.

The dataset plot is extrapolated into an expression that can be used in parametric analyses or assigned to a material property value.

 

Modifying a Dataset

1. On the Project menu, click Datasets.

The Datasets dialog box appears.

2. Click the dataset name you want to modify, and then click Edit.

The Edit Dataset dialog box appears.

3. Optionally, type a name other than the default for the dataset in the Name text box.

4. Type new values for the data points as desired.

The plot is adjusted to reflect the revised data points.

5. When you are finished entering the data point coordinates, click OK.
