Function Plot – Data File

Table of Contents

This option of the Function Plot feature allows evaluating the function in points with a combination of inputs defined in a file. Results are stored immediately as comma-separated values into the project folder, so they can be opened in any text editor or used for further analysis in the software of free choice.

How to use it: #

At first, there is necessary to select the file with input data. These are expected to be in the same format as those in the XDis.txt file – each column represents one input variable, each row is for one sample to be evaluated. Since input variable names are known from the *.json file of uncertainty propagation results, these are used in the output file to create a header. This proved itself helpful for orientation in such files, where function input and output data are stored together. Example of a spreadsheet with results can be seen in Fig. 2, function values are listed in the first column of the file.

Buttons: #

  • Load file: Raises a Load file window where the user selects the input file in a *.txt format. When the file is loaded, input data are tested to be inside the domain of the mathematical model. Outliners are excluded from the list.
  • Apply: Once the Apply button is pushed, the user is asked for the name of the output file and data are stored.
