Use the Computed columns tab to specify operations for the individual signals. These operations create one value for the associated signal (e.g. the average, maximum, or minimum of all the data in one signal).
Values that are defined as calculated columns are passed on to the Report Designer . Because none of the ibaAnalyzer functions from the expression builder are available in the Report Designer, you must perform all calculations here.
Selecting and preparing signals
Add the desired signal to the table either by double-clicking on the signal or using drag & drop. You can also select multiple signals in the signal tree by the standard Windows method of a mouse click + <Shift> or <Ctrl>, and drag them into the table with the mouse.
The Column name column initially contains the source signal's name, which you can change manually.
The Expression column initially contains the channel number of the source signal. You can either enter an expression or use the <fx> button to open the expression builder. The result of the expression should be a signal value. If you do not use an operation or group function for Expression, then ibaAnalyzer automatically extracts the average (AVG) from the signal data.
The X column automatically shows the X-axis mode of the source signal (time-based or length-based).
You can edit the computed columns in the same way as the info columns, see Editing the info columns.
Use the Show column to specify whether the calculated values are also displayed in the ibaAnalyzer interface in the Report info window, see Display of report information.
Search tab
You can search for signals in this tab as usual. You can drag the search results directly into the configuration table.
<Create Logicals>
At different places in ibaAnalyzer, you can define and manage logical expressions. This button creates a group of logical expressions from the defined computed columns. You can then manage the created logical expressions via the Logical signals dialog. When renaming or moving the expressions, all references to them are automatically adapted.
If you have already used the same expressions or the same names elsewhere in ibaAnalyzer and they are not yet grouped, you can select how you want to proceed with these expressions: ignore, overwrite other expression or replace this expression with the other one.
Display in Report Designer
The data of the computed columns is available in the Variables/Fields list in the Report Designer.
