Getting started

To get started using mlpyqtgraph, it first needs to be installed. Refer to installation page for instructions.

Now, mlpyqtgraph can be used in existing python programs.

To get started, try out the full example from the mlpyqtgraph examples.

import numpy as np
import mlpyqtgraph as mpg


@mpg.plotter
def main():
    """ Advanced mlpyqtgraph example """
    plot_args = {'width': 2}

    fig = mpg.figure(title='Another figure')
    fig.width = 600
    theta = np.linspace(0, 2*np.pi, 100)
    mpg.plot(theta, np.cos(theta), **plot_args)
    mpg.plot(theta, np.sin(theta), **plot_args)
    mpg.plot(theta, np.sin(theta + np.pi), style='--', **plot_args)
    mpg.plot(theta, np.cos(theta + np.pi), style='.-', **plot_args)
    mpg.plot(theta, 0.5*np.cos(theta), color='k', **plot_args)
    axis = mpg.gca()
    axis.grid = True
    axis.xlabel = 'x'
    axis.ylabel = 'y'
    axis.xticks = (
        (0.0, '0'),
        (np.pi/2.0, 'π/2'),
        (np.pi, 'π'),
        (1.5*np.pi, '3π/2'),
        (2.0*np.pi, '2π'),
    )
    axis.add_legend(
        'y=cos(x)',
        'y=sin(x)',
        'y=sin(x+π)',
        'y=cos(x+π)',
        'y=cos(x)/2',
    )
