Im a new user of Origin and have some smaller problems.
How do I change the scale? If I want 5 cm to equal 5 units on the X-axis and 5 cm to equal 10 units on the y-axis?

Can I ad a circle with a certain centre and radius?

Assuming that your X and Y values are in cm, go to Format | Axes | Y Axis | Tick Labels and set the Divide by Factor to 0.5. Or use this labtalk command...

layer.y.divideby=0.5;

Create a circle anywhere on the plot using the Toolbox. Then use the following script...

circle.x=x coord. of center position;
circle.y=y coord. of center position;
circle.dx=radius;
circle.dy=radius;

If your X and Y axis scales are different you might need to fiddle with the dx and dy values in order to keep it circular. I hope that helps.

The actual length of the axes is determined by the Layer Area settings on the Size/Speed tab of the Layer Properties dialog. Select Format:Layer (you can also right-click on the layer icon in the upper left-hand corner of the graph and choose Layer Properties from the shortcut menus) and then make the Size/Speed tab active. You can set the units to cm and then modify the width and height values.

Draw circle: Go to View | Toolbars and make sure that Tools is checked. Click the circle button, click anywhere on the plot, move the mouse cursor a bit and release.

Script commands: enter them in the script window. I made a mistake in my earlier post: the actual commands for the circle size are...

circle.dx=diameter;
circle.dy=diameter;
