5.2.2. Fitting to the Lowest Common Value
The Fit lowest common value button enables automatic shifting of the zero-point of single measurement series
to each other. The following can be selected:
Viable Cell Density
Dead Cell Density
Total Cell Density
By means of this function, the zero-point of each series will automatically be shifted on the x-axis, in order to be
able to better compare the measurement series to each other. The lowest common value of all the measurement
series is automatically determined, and the graphs in the diagram are shifted to each other so that the lowest
common value falls on the x-axis at the same point. While doing so, the left-most point of the graph of all the
measurement points is set at value 0.
5.2.3. Measurement Series Offset
In the graph, measurement series are automatically displayed such that all measurement series begin at time
0. The different measurement series can, however, be best compared to each other when the beginning of the
exponential growth phase (log phase) starts at the same time. Therefore, it is possible to shift the curves in the
diagram by changing the offset for each series.
A button in the Offset column of the Data Series area displays the offset set by the user (the button displays 0
[h] , if an offset was not set). Clicking on this button opens the Measurement Offset window. The measurement
series offset can be then manually shifted in this window.
Figure 67: The Measurement Offset window
The offset can be separately entered for each of the fi ve measurement series by clicking the button with the
corresponding number of the measurement series. Large time differences can be entered in days [d], small
ones in hours [h] by clicking on the appropriate buttons
[d] /[h] . The offset can be set by selecting the desired
series number (colored boxes) and then moving the slider to the desired offset. Using the slider will cause an
immediate shift of the measurement series in the diagram so that it can be immediately seen where the best
position for a series is in the diagram.
The smallest time unit that can be set is 0.10 hours. The OK button confi rms the offset values in the graphics.
5.2.4. Variable Axis Calibration
The buttons lin and log are used to determine whether the y-axis should display in a linear (lin) or logarithmic
(log) scaling for cell concentration data. The default value is lin.
The x-axis units can be displayed as either days [d] or hours [h] . Click on the Time[d] below the x-axis to switch
to hours. The x-axis calibration and division will be automatically adjusted.
