Use <a href="https://matplotlib.org/stable/tutorials/intermediate/constrainedlayout_guide.html" rel="nofollow noreferrer"><code>constrained_layout</code></a>. It is more flexible than <code>tight_layout</code> (usually):
<pre class="lang-py prettyprint-override"><code>import matplotlib.pyplot as plt 

idl_t, idl_q = [[0, 20], [8, 24]], [[100, 100], [100, 100]]
dsc_t, dsc_q = [[8, 14], [12, 18]], [[100, 100], [5, 5]]
cha_t, cha_q = [[12, 18], [14, 20]], [[5, 5], [100, 100]]

fig, ax = plt.subplots(figsize=(7, 3), constrained_layout=True)
ax.plot(idl_t, idl_q, color=&quot;blue&quot;, lw=2)
ax.plot(dsc_t, dsc_q, color=&quot;red&quot;, lw=2)
ax.plot(cha_t, cha_q, color=&quot;green&quot;, lw=2)
ax.set_xlabel(&quot;Time (hour)&quot;)
plt.show()
</code></pre>
<a href="https://i.stack.imgur.com/2XONU.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/2XONU.png" alt="enter image description here" /></a>

I am constructing a simple graph with the following code:
<pre><code> plt.figure(figsize=(7, 3))
 plt.plot(idl_t, idl_q, color=&quot;blue&quot;, lw=2)
 plt.plot(dsc_t, dsc_q, color=&quot;red&quot;, lw=2)
 plt.plot(cha_t, cha_q, color=&quot;green&quot;, lw=2)
 plt.xlabel(&quot;Time (hour)&quot;)
 plt.show()
</code></pre>
with input data as following:
<pre><code> idl_t, idl_q = [[0, 20], [8, 24]], [[100, 100], [100, 100]]
 dsc_t, dsc_q = [[8, 14], [12, 18]], [[100, 100], [5, 5]]
 cha_t, cha_q = [[12, 18], [14, 20]], [[5, 5], [100, 100]]
</code></pre>
However, the code somehow cuts the x-label on figure as below:
<a href="https://i.stack.imgur.com/8i5jC.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/8i5jC.png" alt="wrong graph" /></a>
I am pretty sure it is because of changing the <code>figsize</code> and seems that that it allocates label space proportionally to it. See the normal <code>figsize</code> figure below:
<a href="https://i.stack.imgur.com/3cviP.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/3cviP.png" alt="right graph" /></a>
How can I preserve enough space for <code>xlabel</code> with different <code>figsize</code>s? And is it actually supposed to be like this as it seems as a bug for me?
I would highly appreciate your advice!
EDIT 1:
Thank you all for your replies. Although I have chosen <code>tight_layout</code> as a better solution I would definitely suggest you using a method proposed by <a href="https://stackoverflow.com/users/3394386/jody-klymak">Jody Klymak</a>. Please find his implementation in the answers below!

x label is outside of my figure because of figsize
