Be able to sort avg bar plot

In the case where we want to quickly see witch model is the best in this case :

we could add a button to sort the values for each color from lowest to highest

The issue does not name a file or test; start by locating the average bar plot in the visualization code and confirm how its color series and model labels are represented. Done means a control sorts each color's values from lowest to highest and the plot clearly reflects the selected ordering.
