Funsliders are user-friendly Matplotlib sliders

Project description

FunSliders is a simple GUI to manually explore the inputs of a function.

from funsliders import funsliders
def volume(x,y,z):
    return x*y*z
funsliders(volume, [('x',0,5), ('y',1,5,3), ('z',2,5,4)])

A slightly more spectacular example of funslider in action is shown in this video .


First solution, with pip:

sudo pip install funsliders

Second solution, unzip everything in a folder and go with

sudo python develop

Last solution, since it’s a very small module (less than 100 lines) just copy the file or its content anywhere you want to use it.

What else there is to know:

The function to explore can be any function with numerical inputs.

One can also define the slider’s properties using a dictionnary. See Matplotlib’s sliders for all supported arguments:

funsliders(volume,[ {'label': 'x', 'valmin':1, 'valmax':5},
             {'label': 'y', 'valmin':1, 'valmax':5, 'valinit':2},
             {'label': 'z', 'valmin':1 , 'valmax':5} ])

funsliders has two other arguments: - autoexec is True, the function f is executed every time the sliders are changed, using the argument values indicated by the sliders. If autoexec is False, f is only run when the user presses Enter. - If history is True, the current value of all arguments is printed to the console every time the function f is run.
