Let's start and draw a simple parabola f(x)=x². Therefore
- Open a "settings" dialog. You can
- choose expressions->new from the menu.
- press the shortcut <CTRL>+<N>.
- choose expressions->overview from the menu and then press the "new" button.
- press the "new" button in the toolbar
- Type "x^2" (without the quotes). The editline is already selected.
- Press Enter (or click on the "Ok" button).
- (Press Enter once more if you opened the overview dialog.)
- That's it! The parabola is drawn in the plot window.
That wasn't too difficult, was it?
Now some advanced technics: let's draw a sine using a blue pen.
- Open a "settings" dialog. See above for details.
- Type "sin(x)" in the editline.
- Press the "color" button.
- Select the blue color in the color selection dialog.
- Click on the "Ok" button.
- Leave the settings dialog by pressing "Ok" or Enter.
- That's all!
