Graphs Page Legend Toolbar

This toolbar allows you to select multiple data sets to plot (up to 5) and select which color and

marker to use for each data set. To select a data set to be plotted, click the box to the left of the

marker so that a check mark is displayed. To un-select a data set so that it is not plotted, click the

box to the left of the marker so that a check mark is NOT displayed. Once the appropriate data sets

to be plotted are selected, click the r

eplOt

button in the Options toolbar to update the graphs.

The top line in the toolbar always displays Captured Data and cannot be changed. Select this data

set to graph freshly collected (i.e., unsaved) data. The bottom four lines are used to select and load

data from disk files. To select a file either double-click the intended line or select the line with a

single click, then click the B

rOwSe

button (i.e. the button with the three (3) dots or ellipsis). The Open

File dialog box appears allowing you to navigate to and select the desired data file to graph.

The R

button must be clicked after making any changes to the

state of the Data Legend toolbar in order for the changes to be seen on

the graphs.

On the graphs, the data is plotted using the color specified for the selected data sets in the Data

Legend toolbar. In addition, if the Data Markers option is turned ON, the appropriate data marker

from the legend is displayed on each graph for each data point.

IV.8.5 Examples of Yield Test Programs

IV.8.5.1 Example Application: Hair Gel

The test method and data shown in Figure IV-63 show an analysis of yield from a typical hair gel

product. It is usually desirable to measure yield on products without transferring them from their

containers because doing so would “pre-shear” the material. Hair gel is normally sold in shallow

jars, as was the case with this sample. The V-73 vane spindle was selected because it is the smallest

and could be completely immersed in the shallow jar. An RVDV-III Ultra Rheometer was used

for the test.
