The DY button yields a Deviation Plot

The DY% button yields a Percent Deviation Plot

The Waring button yields a plot of the Waring function vs Temperature

The Waring Function is defined as R * [d ln(p) / dT], R is the gas constant, and T and p are temperature and pressure.

For many materials, the Waring Function displays a minimum for 0.8 < T/T_c < 1.0, where T_c is the critical temperature.

The +/- button shows/hides estimated uncertainties for the plotted data points.

NOTE: The +/- ranges indicate approximate uncertainties for the experimental values, except in the Recommended Values branch of the Navigation Tree, where they represent uncertainties for the recommended values.

The Connect button shows/hides connecting lines for data points within the same data set

NOTE: All data for a particular property from a single bibliographic source typically represent one data set. There can be more than one data set from a single source, if more than one sample was studied or more than one experimental method was used.

The Rejected button shows/hides data points rejected in the evaluation process

The Full view button rescales the plot to full size after viewing a detail

Rescaling of the plot allows all data to be visible.

The mouse can be used to define a region for detailed viewing

Double Click on any data point in a plot to determine its source

NOTE: The Bibliographic Source Details can viewed through the Data Table.

Data as a function of 2 variables

PLOT FEATURES:
+/-: Show/Hide Uncertainties, Connect: Connecting Lines , Rejected: Show/Hide rejected data, Full View: Show all data,
and Change Plot Variable, Exploring Details, Compressibility(Z) and Data Point identification in a plot.

The example shows plots of density = f (T& p) for quinoline after evaluation (from the Default Representations branch of the tree).

Alternative Views: Properties can be plotted as a funtion of temperature (T) or pressure (p).

The example shows a plot of density = f (T) and f(p) for o-xylene after evaluation.

Compressibility Factor: Density data may be plotted as the compressibility (Z)
