| The Data Plotter accepts two types of input. The first type of input is entering an expression as a function of t, f(t), in the “y =” input field. The |
| independent variable in the expression should be a “t”, although an “x” is also allowed. When entering this type of input, do not use the input fields |
| or buttons to left of the “y =” input field. The ‘Δt =’ input field is to enter the Δt interval. If left blank, the Δt defaults to 0.50 s. The Area |
| button displays the area bound by the graph. If you want to select this option, you must click the area button before clicking the Play button. The |
| default for this option is not to display the area. The L Reg button displays the regression line and the regression table under the graph. As of now, |
| only linear regressions are possible. The default for this option is not to display regression results. |
| |
| The second type of input is manually entering values for x and y. When entering this type of input, do not use the input fields to the right of the |
| Clear button. The two types of input are mutually exclusive. After entering the x and y values, click the Add button. This will display the point in |
| the graph area, the coordinates in the Data Table, and the regression results on the “fly”. The Clear button blanks the x and y input fields. When |
| you are finished with a particular trial, click the Reset button. |
