Screen Graphs: There are two types of screen graphs: propeller curves and column graphs. Propeller curves are displayed by selecting or highlighting a data row, or by clicking the Calculate button on a Series Dialog Box. Propeller curves consist of three plots:
The propeller Series, Sigma, P/D, BAR, Z and Cup values are shown above the propeller curves.
Column graphs are generated from data in columns. Axis values are chosen by left clicking on two column headers in the Data Window. The first column clicked will contain X values (horizontal axis), and the second will contain the Y values (vertical axis). To change the Y values for a graph, simply left click a different column header. To change the X values, first click anywhere in the Graph Window then left click a different column header. The column graph below was created by clicking on the MPH column header first, then clicking on the Horsepower column header.
Another way to generate a column graph is by selecting Tools \ Graph Cols... from the main menu. Simply follow the directions in the dialog box that is displayed.
