If the "Statistics" - button is clicked the following window will pop up:

 

For the x-axis of your statistics you can use all columns of the list of results.

For the y-axis you can only use column whose associated field from the data base contains numerical values only (integers, floating-point numbers).

These are only descriptive statistics: histograms, plots and their individual parts.

The interpretation of the y-values exclusively depends on the scale measurement of the data used (the data is, however, displayed in such a way as if the values were all interval-scaled).
