- Simple mode: where a single existing calculation is selected from a drop-down menu.
- Custom mode: where a new, custom calculation is built using combinations of existing functions, inputs, and outputs.
The video and knowledge article below describe the process of how to use these two modes.
To create a new calculation, left mouse click on an existing signal name in the channel header in Chart View to view the signal’s properties. Now, click on the "Add Calculated Signal…" button. As shown in the image below, you will now see the Calculation Tab where you can either create a simple or custom calculation.
To create a new custom calculation, left mouse click on the "Customize…" button. You will now see the Custom calculation dialog. This dialog is split into three areas: (1) A canvas where you construct your calculation. (2) A preview where input and output signals are shown; and (3) A function library that contains the building blocks of your calculation such as existing calculations, inputs, outputs, and parameters.
A calculation is built up by adding one or more functions between the Input and Output Nodes. Functions can be found by typing in a partial or complete function name into the search field at the top of the Function Library. In the example below, the SmoothSeconds Function has been located. Left mouse clicking once on SmoothSeconds in the search results list shows detailed documentation on the function. The SmoothSeconds Function can be added to the calculation by dragging the list entry for SmoothSeconds (or the Node preview in the documentation area) to the middle of the line connecting the Input and Output Node.
Note: a warning icon appeared in the SmoothSeconds Node when the path is removed. This is because when the SmoothSeconds Node is connected to an output, it requires a valid data source input. Calculations that contain errors cannot be applied (the Add/Update calculation button will be disabled). The error warning can be removed by reconnecting the Input Node to the SmoothSeconds Node.
