Graph drawing using matplotlib

I use graph drawing a lot, so I personally created the minimum necessary. I'll omit the explanation of the functions in the basic matplotlib, as others have probably explained them. ʻImport The import of matplotlib.pyplot` is omitted.

plot_graph.py

def plot_graph(x, y=[], graph_name='graph.png', \
    save_flag=True, show_flag=False, label_x='', label_y='', label='',title=''):
    if label: pyplot.plot(x, y, label=label)
    else: pyplot.plot(x, y)
    if title: pyplot.title(title)
    if label_x: pyplot.xlabel(label_x) 
    if label_y: pyplot.ylabel(label_y)
    if save_flag: pyplot.savefig(graph_name)
    if show_flag: pyplot.show()

As a default setting, if you give x, y as an argument, it will be written to the graph.png file. x, y is a sequence input. As an option, I put the file name, save or not, changeable to show, each axis label, graph label, title. I thought it would be better to separate save_flag and show_flag, but I thought it would be easier to understand when I saw it later.

Partially functionalized below

part of plot

plot_only.py

def plot_only(x, y=[], label=''):
    if label: 
        if y: pyplot.plot(x, y, label=label)
        else: pyplot.plot(x, label=label)
    else: 
        if y: pyplot.plot(x, y)
        else: pyplot.plot(x)

Correspondence when there is a label and there is only one argument

Labeling part

add_label.py

def add_label(label_x='', label_y='', title=''):
    if title: pyplot.title(title)
    if label_x: pyplot.xlabel(label_x) 
    if label_y: pyplot.ylabel(label_y)

Output part

output_graph.py

def output_graph(save_flag=True, show_flag=False, graph_name='graph.png'):
    if save_flag: pyplot.savefig(graph_name)
    if show_flag: pyplot.show()

Now that we have a function, make plot_graph.py smart

new_plot_graph.py

def new_plot_graph(x, y=[], graph_name='graph.png', \
    save_flag=True, show_flag=False, label_x='', label_y='', label='',title=''):
    plot_only(x, y, label)
    add_label(label_x, label_y, title)
    output_graph(save_flag, show_flag, graph_name)

I don't use legend, display range, xtrick, etc. so much, so I didn't write it this time. Like this, it was a function I needed.
