2.1. plotting an expression

Let's start and draw a simple parabola f(x)=x². Therefore

  1. 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
  2. Type "x^2" (without the quotes). The editline is already selected.
  3. Press Enter (or click on the "Ok" button).
  4. (Press Enter once more if you opened the overview dialog.)
  5. That's it! The parabola is drawn in the plot window.
That wasn't too difficult, was it?

2.2. plot in a different color

Now some advanced technics: let's draw a sine using a blue pen.

  1. Open a "settings" dialog. See above for details.
  2. Type "sin(x)" in the editline.
  3. Press the "color" button.
  4. Select the blue color in the color selection dialog.
  5. Click on the "Ok" button.
