5.16.1 Data properties 5.16.2 Scale properties The Data properties of the Phase plot are the following. Display margins: enables or desables the plotting of phase shift tolerance band. Display invalid data: enables or desables the plotting of invalid data. PDA type: displays PDA receiver type (read only) X min., X max. These properties determine the minimum and maximum values on the X-, and Y- Y min., Y max. axis respectively. If the properties X scaling and Y scaling are set to Automatic, the minimum and maximum values will be adjusted automatically to match the data shown. X scaling, Y scaling These properties can be either Automatic or Manual, with Automatic being the default setting. When scaling is set to Automatic, the minimum and maximum values of the axis in question will be automatically adjusted according to the data, while Manual scaling, means that the user specifies minimum and maximum-values manually. 5-84 BSA Flow Software: Project explorer objects
5.16.3 Display properties The default setting Automatic ensures that all samples are included in the initial plot, while subsequently the user can zoom in on areas of specific interest by switching to manual scaling. Whenever the user changes a minimum or maximum value manually, the scaling of the corresponding axis will switch to Manual. Data background color: this property defines the background color of the plot. Valid color: this property defines the color of the valid particles. Invalid color: this property defines the color of the invalid particles. Point size: this property defines the size of the dots. Title: to add a title to the plot. Note The font and font size of titles and text on axes can be globally defined for all graph objects in the Tools-Options dialog under the Display tab. 5.17 Diameter statistics This object is only available with a PDA configuration (size add-on). The diameter statistics object provides a more advanced statistical analysis of the measured particle diameters. The results can be output graphically, in tabular form or exported. Possible child objects are List, Export and all graph types from the advanced graphics add-on. As an example, a list output is shown in Figure 5-77 and a profile plot taken in a water spray is given in Figure 5-78. Figure 5-77: List output from the diameter statistics object.
