How to show/save the output about july HOT 4 CLOSED

Hello @Jankowski-J - try matplotlib.pyplot.savefig method (documentation), it's a standard built-in method in matplotlib to save a figure class object. Example: stackoverflow question

Package is a purpose-based wrapper above matplotlib, so all logic and methods are inherited for respective objects.

I've tried what you have suggested, I've also looked into the properties available in object returned by july.heatmap() method. I can't seem to find any relevant method to save the image.

The heatmap variable is of type AxesSubplot and I don't know how to save that to file.

Below is a snippet of my code:

import numpy as np
from plotly_calplot import calplot

import matplotlib.pyplot as plt

import july
from july.utils import date_range


def main():
    dates = date_range("2020-01-01", "2020-12-31")
    data = np.random.randint(0, 14, len(dates))

    heatmap = july.heatmap(dates, data, title='Github Activity', cmap="github")

    # both of these lines throw an exception
    heatmap.save_fig("saved_hm.png")
    plt.save_fig("test_heatmap.png")


if __name__ == "__main__":
    main()

@Jankowski-J - try plt.savefig("test_heatmap.png") instead of plt.save_fig("test_heatmap.png"), you have a typo underscore (..._...) in a name of a method (see documentation). This method will take the current figure (~the last active figure) and save it

heatmap = july.heatmap(dates, data, title='Github Activity', cmap="github")
plt.savefig("test_heatmap.png")

Alternatively, try the next snippet because heatmap object is <class 'matplotlib.axes._subplots.AxesSubplot'>. Matplotlib allows to save figure objects not axes objects (see example stackoverflow question). It also allows to save the selected figure

fig, ax = plt.subplots(1, 1, figsize=(12, 10)) # create figure object and one axes objects
heatmap = july.heatmap(dates, data, title='Github Activity', cmap="github", ax=ax) # plot a chart to ax subplot
fig.tight_layout() # auto adjust the padding between and around subplots.
fig.savefig("saved_hm.png") # save figure

Also, check the dpi and facecolor params to increase the image quality and change the background color (from transparent to needed color code).

Also, there is already a pull request to save it inside the package interface - #27

Thank you for your explanation @Witold1 , now I can save the output.
I have no further questions, so I will close the issue soon.
