AppendAnimate class

class postmd.animate.AppendAnimate(*args, fps=20, dpi=72, range_mode='auto')

Bases: BaseAnimate

animate data by appending data to the figure.

Parameters:

• *args – a set of y data (ydata1, ydata2, ...), or x, (ydata1, ydata2, ...). Each ydata should be a 1D array.

• fps (int, optional) – Frames per second (FPS) setting for animation. Defaults to 20.

• dpi (int, optional) – Dots per inch (DPI) resolution for animation. Defaults to 72.

• range_mode (str, optional) – Determines the behavior of x and y limits in the animation. Defaults to 'auto'. - If set to 'auto', the x and y limits will automatically adjust to the data range. - If set to 'fix', the x and y limits will be fixed to a specific range. The fixed range is from the min to max of data plus 5% margin.

show()

show the animation of data.

save(filename, output_format=None)

save the animation of data to file.

Parameters:

• filename (str) – file name to output

• output_format (str, optional) – the output format. Now only support gif, mp4, and avi. Defaults to None, meaning the output format is inferred from the filename extension.

Example

import numpy as np
from postmd.animate import AppendAnimate

if __name__ == '__main__':
    y_data = np.sin(np.linspace(0, 2 * np.pi, 100))  # Assume this is the sine wave data to be animated
    x_data = np.linspace(0, 10, 100)  # Corresponding x-axis data

    animator_auto = AppendAnimate(x_data, y_data, fps=20, range_mode='auto')
    # add label of x and y axis.
    animator_auto.ax.set_xlabel("Time")
    animator_auto.ax.set_ylabel("Sine Wave")
    # animator_auto.show()
    animator_auto.save("animate_sine_wave_auto.gif")



    animator_fix = AppendAnimate(x_data, y_data, fps=20, range_mode='fix')
    animator_fix.ax.set_xlabel("Time")
    animator_fix.ax.set_ylabel("Sine Wave")
    # animator_fix.show()
    animator_fix.save("animate_sine_wave_fix.gif")
