Collecting Data Points from a Graph

From the Graph screen, you can store sets of coordinate values and/or math results for
later analysis. You can store the information as a single-row matrix (vector) on the Home
screen or as data points in a system data variable that can be opened in the Data/Matrix
Editor.

1. Display the graph. (This example shows y1(x)=5ùcos(x).)
2. Display the coordinates or math results you want to collect.
3. Save the information to the Home screen or the sysData variable.8 · (Home
screen) or 8 b (sysData variable)
4. Repeat the process as necessary.
Note: To display coordinates or math results, trace a function with … or perform an
‡ Math operation (such as Minimum or Maximum). You can also use the free-
moving cursor.
