History plot

Design Exploration Plots History Plot

A History Plot is used to follow the evolution of one or more parameters during the design exploration process. It plots the parameter(s) (on the y axis) against the run or iteration number (on the x axis).

Figure 98: Example of a History Plot

When History Plot is selected, the dynamic part of the dialog box is as shown in the following figure.

Figure 99: History Plot setup

To plot a parameter, select it in the left hand side list and click on the >> button. It then appears in the Items to plot list.

You can add as many parameters as you want.

If you want to remove a parameter from the Items to plot list, select it and click on the << button.

When you click on the OK button, there are two possibilities:

• If you select the Individual plots option the application creates a plot for each parameter in the Items to plot list.

• If you select the All in one plot option, all the parameters in the Items to plot list are plotted in the same plot window.

If the design exploration process is still running when you create this plot, the automatic update is on in order to follow the evolution of the process. Otherwise, the automatic update is off.

Scatter plot

Design Exploration Plots Scatter plot

A Scatter plot is a plot of the values of a parameter against the corresponding values of another parameter.

It can be used to visualize the convergence of a Genetic algorithm.

Figure 100: Example of a scatter plot

It can also be used to determine a correlation between parameters. The figure above shows a scatter plot involving two parameters which are linked by a linear correlation.

When Scatter plot is selected, the dynamic part of the dialog box is as follows:

Select the parameters you want to plot using the drop-down lists and click on the OK button.

If the design exploration process is still running when you create a plot, the automatic update is on in order to follow the evolution of the process. Otherwise, the automatic update is off.
