| When the calculation has finished, create a new window of type **'(p6) Plot: TTP-diagram'**. In the **'options'** window, expand the **'plots'** section and right-click in the area under **'plot#0'** to show the context menu. Select **'new series'** and choose **'ttp-curve'** from the sub-menu on the right. Next, it is necessary to decide on the type of TTP contours required.

| * Absolute: the contours correspond to different values of the phase fraction <nowiki>F$FCC_A1#01_P0</nowiki>. | * Absolute: the contours correspond to different values of the phase fraction <nowiki>F$FCC_A1#01_P0</nowiki>. |
| * Relative: a contour with a value of **'x'** for a particular temperature denotes the time at which the ratio of <nowiki>F$FCC_A1#01_P0</nowiki> to its maximum value at that temperature is equal to **'x'**. The maximum values of <nowiki>F$FCC_A1#01_P0</nowiki> are approximately equal to the equilibrium phase fractions <nowiki>F$FCC_A1#01</nowiki> shown above. | * Relative: a contour with a value of **'x'** for a particular temperature denotes the time at which the ratio of <nowiki>F$FCC_A1#01_P0</nowiki> to its maximum value at that temperature is equal to **'x'**. The maximum values of F\$FCC_A1#01_P0 are approximately equal to the equilibrium phase fractions F$FCC_A1#01 shown above. |
| * Relative max f: in this case, contour values represent ratios of <nowiki>F$FCC_A1#01_P0</nowiki> to its maximum value overall. These contours have a similar form to the **'absolute'** contours, but different numerical values. | * Relative max f: in this case, contour values represent ratios of <nowiki>F$FCC_A1#01_P0</nowiki> to its maximum value overall.

| Select **'relative'** from the **'refer to f'** drop-box at the top of the **'options'** window. Then expand the **'series'** section of **'options'**, which should look as shown in the image below. Select the phase FCC_A1#01_P0 from the **'phase'** drop-box and enter **'0.05'** into the **'y-data'** line. | Select **'relative'** from the **'refer to f'** drop-box at the top of the **'options'** window. |

| Add two more series to show the contours for ratios of 0.5 and 0.95 on the same diagram. The resulting diagram should look like this: | Add two more series to show the contours for ratios of 0.5 and 0.95 on the same diagram. The resulting diagram should look like this: |

| In the plot below, the contours correspond to different values of the phase fraction <nowiki>F$FCC_A1#01_P0</nowiki>. Note that the higher values are only attained at lower temperatures, because the equilibrium value of <nowiki>F$FCC_A1#01</nowiki> decreases with increasing temperature. The maximum value of <nowiki>F$FCC_A1#01_P0</nowiki> is around 7.8e-3. | In the plot below, the contours correspond to different values of the phase fraction F\$FCC_A1#01_P0.
