### 4.2.1. XY Plot Features

A number of additional features of the performance map plot are:

- Multiple Legends

  When comparing multiple designs, the XY Plot uses two separate legends to distinguish the curves. The regular color legend on the right determines the speed % of each curve whereas an additional line style legend in the top left hand corner of the plot indicates the different turbomachinery-related systems.

- Base duty point

  The base duty point is always included in the calculation and the plot. This is shown as an open square. All other calculated points are shown with an ‘X’. When the mouse is positioned over a base duty point, a tooltip indicates that it is a base duty point and names the originating turbomachinery-related system.

- Include ‘out-of-date’ points

  By default, only points that are up-to-date in the parameter manager are displayed. However, in some cases, it is desirable to include out-of-date calculations. To do this, right-click in the plot area and select Include ‘out-of-date’ points from the context menu.

- Mouse coordinate tracking

  In addition to showing the major gridlines to indicate the position of a plotted point, the location of the mouse in the plot is tracked and the coordinates are displayed in the lower right hand corner of the plot. This provides a simple way to obtain an accurate position of a calculation point. The exact numerical values are displayed in the table to the left of the plot area.

- Tooltips

  You can hover the mouse over a plotted point to see the design point number.

- Maximize

  If you want to change the screen size of the XY plot, click Maximize in the top right corner of the plot window. This makes the plot fill the Turbomachinery Performance Map dialog box and also makes the dialog box resizable. To return the plot to its regular size, click Close in the top right corner of the plot window.

- Save CSV File

  To export the performance data displayed, click Save CSV file in the top left corner of the plot window to write a comma separated value file that is suitable for use in Microsoft Excel and other third-party applications.
