pyEPVis 0.0.3

A Expression and Particle movement visualizer package

pyEPVis

A package that allows you to easily visualize single or two variable functions and allows you to visualize particle/point movements along two or three Dimensions with an interactive plotly visualization.

Used for Development

Using the package

Install the package using the command

pip install pyEPVis

Visualizing Single Variable Functions

from pyEPVis import do_fx_plot
do_fx_plot(formula = "x**4 - 10*(x**3) - 2*(x**2) - 5*x + 4",xstart = -100,xend = 100,step = 1).show()

Visualizing Double Variable Functions

from pyEPVis import do_fxy_plot
do_fxy_plot(formula = "(x**2 + y**2)/(x - y)",xstart = -5,xend = 5,ystart = -5,yend = 5,step = 0.1,colorscale = 'Viridis').show()

Visualizing 2D Particle Movements

from pyEPVis import animate_xy_particles
animate_xy_particles(x = [[1,4,7],[4,7,1],[7,1,4],[1,4,7]],y = [[1,4,1],[4,1,1],[1,1,4],[1,4,1]],colors = ["red","blue","green"]).show()

Visualizing 3D Particle Movements

from pyEPVis import animate_xyz_particles
animate_xyz_particles(x = [[1,8,7],[3,3,6],[1,1,1]],y = [[5,2,2],[7,9,0],[5,2,6]],z = [[1,2,3],[4,5,6],[7,1,1]],colors = ["red","green","blue"],framespmov = 15).show()

Warnings

• (Note: for function evaluation please stick to x and y and not other variables as it will lead to evaluation errors and framespmove should be high in order to visulaize the movement smoothly in animate_xyz_particles)

Other Help

• Use the help(enter_function_name_here) function to refer to the full documentation of the function.
• The figure is a plotly.graph_objects.Figure variable it can be further modified for including more plots inside the figure.
• All math package syntaxes along with python expressions are supported as well, to use the math package in your formula and use it as follows: math.enter_function_name()
