Graphing XY Data
Complete the following steps to display an array of points on a single-plot XY graph.
- Select an XY graph located on the Controls»Graph palette, and place it on the front panel.
- Build a block diagram with the following objects:
- Divide function located on the Functions»Numeric palette.
- Multiply function located on the Functions»Numeric palette.
- Sine function located on the Functions»Numeric»Trigonometric palette.
- Bundle function located on the Functions»Cluster palette.
- For Loop located on the Functions»Structures palette. Drag the loop around all objects on the block diagram except the XY graph terminal.
- Expand the Bundle function to include two inputs.
- Wire the x/y output of the Divide function to the x input of the Sine function.
- Wire the sin(x) output of the Sine function to the first (top) input terminal of the Bundle function.
- Wire the x*y output of the Multiply function to the second (bottom) input terminal of the Bundle function.
- Wire the iteration terminal of the For Loop to the x input of the Divide function and to the x input of the Multiply function.
- Right-click the y input terminal of the Divide function and select Create»Constant from the shortcut menu. A numeric constant appears.
- Enter 10 in the constant and press the <Enter> key.
Macintosh and UNIX Press the <Return> key.
- Wire the constant to the y input terminal of the Multiply function.
- Wire the output terminal of the Bundle function to the XY graph terminal. An auto-indexing tunnel appears where the wire intersects the loop border.
- Right-click the count terminal of the For Loop and select Create»Constant from the shortcut menu. A numeric constant appears.
- Enter 100 in the constant and press the <Enter> key.
Macintosh and UNIX Press the <Return> key.
- Run the VI.
Refer to the XY Graph VI in the examples\general\graphs\gengraph.llb for an example of graphing XY data.
