SAFE TOOLBOXES^{®} offers you the possibility to plot a univariate function seamlessly. In Excel sense, a univariate function can be thought as a function that maps the value of a single input cell to a result in one output cell.
The output function can contain a reference to multiple cells. In this case, a univariate plot can be done by selecting one input cell to change and keeping the others untouched. In math terms, this is the definition of a level curve plot.
An example is a good way to understand how to use this tool. Suppose you have the following spreadsheet and want to see how the values of cell B3 affects the values of cell B4 in the interval 10 to 10.
