## [matplotlib.pyplot.subplot](https://matplotlib.org/stable/api/_as_gen/matplotlib.pyplot.subplot.html)
|
|
|
|
```python
|
|
matplotlib.pyplot.subplot(*args, **kwargs)
|
|
```
|
|
|
|
> Add an Axes to the current figure or retrieve an existing Axes.
|
|
>
|
|
> This is a wrapper of Figure.add_subplot which provides additional behavior when working with the implicit API (see the notes section).
|
|
|
|
> ***args** : int, (int, int, index), or SubplotSpec, default: (1, 1, 1)
|
|
>
|
|
> The position of the subplot described by one of
|
|
> * Three integers (nrows, ncols, index). The subplot will take the index position on a grid with nrows rows and ncols columns. index starts at 1 in the upper left corner and increases to the right. index can also be a two-tuple specifying the (first, last) indices (1-based, and including last) of the subplot, e.g., fig.add_subplot(3, 1, (1, 2)) makes a subplot that spans the upper 2/3 of the figure.
|
|
> * A 3-digit integer. The digits are interpreted as if given separately as three single-digit integers, i.e. fig.add_subplot(235) is the same as fig.add_subplot(2, 3, 5). Note that this can only be used if there are no more than 9 subplots.

import numpy as np

rng = np.random.default_rng()
|
|
|
|
plt.figure(1)
|
|
plt.subplot(2, 2, 1)

plt.imshow(rng.random((10, 100)))
|
|
plt.title("A")
|
|
plt.subplot(2, 2, 2)
|
|
plt.imshow(rng.random((5, 10)))
|
|
plt.title("B")
|
|
plt.subplot(2, 2, 3)
|
|
plt.imshow(rng.random((50, 20)))
|
|
plt.title("C")
|
|
plt.subplot(2, 2, 4)
|
|
plt.imshow(rng.random((100, 200)))
|
|
plt.title("D")
|

plt.show()

matplotlib.pyplot.subplots_adjust(left=None, bottom=None, right=None, top=None, wspace=None, hspace=None)
|
|
```
|
|
|
|
> Adjust the subplot layout parameters.
|
|

|
|
> Unset parameters are left unmodified; initial values are given by **rcParams["figure.subplot.[name]"]**.
|
|

|
|
|
|
> **left** : float, optional
|
|

|
|
> The position of the left edge of the subplots, as a fraction of the figure width.
|
|
>
|
|
> **right** : float, optional
|

>
|
|
> The position of the right edge of the subplots, as a fraction of the figure width.
|

|
|
> **bottom** : float, optional
|
|
>
|
|
> The position of the bottom edge of the subplots, as a fraction of the figure height.
|
|
>
|
|
> **top** : float, optional
|
|
>
|
|
> The position of the top edge of the subplots, as a fraction of the figure height.

|
|
> **wspace** : float, optional

|
|
> The width of the padding between subplots, as a fraction of the average Axes width.

|
|
> The height of the padding between subplots, as a fraction of the average Axes height.
