•

Lists created in Lists & Spreadsheet can be accessed as a variable.

•

Variables must be named before they can be used in Data & Statistics.

•

Tap the Add Variable field located in the center of the x-axis or y-axis to choose a defined variable name.

•

The default plot for one variable is a dot chart. The data points in the default caseplot reposition to represent the elements of the selected variable.

•

The default plot for two variables is a scatter plot. The data points shift to represent the elements of both variables on a scatter plot.

Pinch or spread either the horizontal or vertical axis to modify its scale.

-OR-

Drag either axis to shift the axis while retaining its scale.

To restore the original size and location of the plotted data, tap Tools > Window/Zoom > Zoom-Data.

 

When you plot a value on an existing plot, it is displayed as a vertical line in the work area. You can plot a single number or any expression that evaluates to a number. If the value is dependent on the data, the line updates to reflect changes made when you drag a point or make changes in the Lists & Spreadsheet application. The plotted value must be in the domain of the axis.

To plot a value:

1.

Tap Tools , go to Analyze, and then tap Plot Value.

2.

Type the value you want to plot, and then tap ENTER.

 

Use Plot Function to graph a function for comparison to an existing plot. To plot a function:

1.

Create or open a problem that includes variables that are plotted in a Data & Statistics work area. Ensure the work area contains both a horizontal axis and a vertical axis.

2.

Tap Tools , go to Analyze, and then tap Plot Function.

3.

Type the function in the entry field and tap return.

Note: You can rename the function by typing over f1(x): with another name.
