CrystalDiffract lets you display diffraction patterns from real experiments. If you need to, you can create a pattern directly in the program. CrystalDiffract will build a dummy "observed pattern" and present you with an editing window so you can enter your own values.
Do one of the following:
Click the toolbar's Add button, then choose New Observed Pattern from its popup menu.
Choose File > Add New Pattern > Observed Data.
