1) You can save graphs or results by clicking on "Options" and choosing "Export." This will save your results under "My Results," so that you can refer back to it. 2) Once a graph has been saved, you can select it from "My Results" and right-click (control-click) on it to save it as an image on the desktop of your computer. This should produce an image file that can be renamed and submitted in your homework. 3) Data can also be saved, though in a slightly different fashion. Once the numbers have been entered into the spreadsheet, you can select "Data," then "Data table," then "Export." You can choose columns of data to save, and have several other options. The default set seems to be fine for most purposes. Click "Export," and the data will be displayed below, where it can be selected and saved on your computer (or copied into a document). 4) You can delete all entries in the data table/spreadsheet by clicking "Stat," then "Data table," and selecting "Clear."
