BSA Flow Software Installation and User's Guide - CSI

6.1 Advanced Graphics Add-on
The main software package is designed primarily for data acquisition, and
offers only very limited data presentation capabilities.
Histograms are included to assist the user in properly setting up the system,
but beyond that, the main software package offers no means of graphically
presenting the results.
The latter is the topic addressed by the Advanced Graphics Add-On, offering
a number of new objects, that can be used to present raw samples as well as
calculated quantities.
When the Advanced Graphics Add-On is installed, five new objects may
appear in the list of options when you create a new object:
• 2D Plot
• 2D Histogram
• 3D Plot
• Profile plot
• Vector plot
Required input While the 2D Plot, 2D Histogram and 3D Plot can be the child of any
object supplying data, Profile plot and Vector plot display statistical mean
values and thus can only be child to the Moments object, a Filter object
after Moments or a Transform object after Moments. Furthermore, the
Vector plot requires at least two measured velocity components.
Within these limits anything can be plotted: From the main software package
you can create time-history plots of the raw PDA-samples, or present mean-
and rms-values varying in different measuring positions.
From the cyclic phenomena Add-On you can plot phase-sorted and/or
-averaged data, and obviously the Spectrum and Correlation Add-On will
yield data, that can be presented graphically as correlations and spectra.
All of this is based on LDA-data, but if the A/D-Option is installed, you will
also be able to create plots showing pressure, temperature or something else,
and obviously any other quantity derived from this (mean, rms, phase
average, correlation, etc.).
Zooming and Panning To have a closer look at some details in a plot, you can temporarily zoom in
on an area of a plot, and pan this area left, right up and down. You can also
read values from a plot with a simple mouse-click. This as well as Zooming
and Panning is described in more detail in section 6.1.8.
Exporting plots Any plot (including histograms) can be exported to other documents.
This is done using copy and paste via the Clipboard, or by exporting to a
graphic image file.
Exporting plots is described in more detail in section 6.1.9.
6.1.1 Common properties of graphs
Certain properties such as fonts, background colour and footers is commonly
defined through the Tools-Options menu.
