conda create -y -n app-env python=3.10

conda activate app-env

Interface

On the top left, you will see a summary of the current configuration. On the right, you will find the paremter list.

from left to right :

the name of the paramter
a slider to quickly explore values
arrow buttons to move from one value to the next
a text box where you can input your desired value. The closest possible value will then be selected.
a button to automatically "play" the parameter from its current positition to its maximum
interval during which each parameter is displayed while playing.

To navigate the plot:

left-click + drag to move around
right-click + drag to zoom
scroll wheel to zoom
for each kind of movement, you can do it while the cursor is hovering over one of the axis. In that case, only that axis is affected.
to go back to a view that fits everything, click on the small "A" at the bottom left.
to hide/show a line, click on it in the legend. You can also click+drag on the legend to move it around.
double click on the purple title bar (left side or top) to pop out the plot in its own window.
