CrystalDiffract lets you edit the composition of your mixture by changing the relative proportions of the phases involved. You can do this in one of two ways: by editing an individual pattern's mixture fraction; or by editing the Mixture as a whole (which gives more precise control):

Editing an individual component Show

Do the following:

  1. From the Patterns list, locate the pattern whose phase proportion you want to change. Select this pattern.

  2. In the Format List, open the Position & Scale group.

  3. Adjust the Mix. Fraction slider control to set the relative phase proportion for this component.

    (Note that CrystalDiffract will automatically adjust the proportions of any other phases, to ensure that the overall sum of mixture components remains constant. If you need more precise control, you will need to edit the Mixture directly, as described below.)

Editing the entire mixture Show
  1. Select the Mixture you wish to edit (e.g., by clicking on its name in the Patterns list).

  2. Open the Mixture group in the Parameters Inspector.

  3. Adjust the slider controls, or use the text fields, to set the phase proportions for individual mixture components.

To specify an explicit composition for the mixture Show
  1. Select the Mixture you wish to edit (e.g., by clicking on its name in the Patterns list).

  2. Open the Mixture group in the Parameters Inspector.

  3. Choose: Zero Phase Proportions in the Mixture list's Actions menu. All phase proportions are reset to zero, and the Lock mixture total control is unset.

  4. Adjust the slider controls, or use the text fields, to set the phase proportions for individual mixture components.

  5. Turn on the Lock mixture total checkbox.

Resetting the mixture Show
  1. Select the Mixture you wish to edit (e.g., by clicking on its name in the Patterns list).

  2. Open the Mixture group in the Parameters Inspector.

  3. Choose: Equalize Phase Proportions from the list's actions menu. The mixture composition is reset, so that all components have the same phase proportions.
