what is plt.subplots code example

Example 1: plt subplots figsize

fig, ax = plt.subplots(10,4, figsize=(16,40))

Example 2: matplotlib subplots

fig = plt.figure()

# total_rows, total_columns, subplot_index(1st, 2nd, etc..)
plt.subplot(2, 2, 1)
plt.plot(x, y)

plt.subplot(2, 2, 2)
plt.plot(x, y)

plt.subplot(2, 2, 3)
plt.plot(x, y)

plt.subplot(2, 2, 4)
plt.plot(x, y)

Example 3: get subplots in matplotlib

fig,ax = plt.subplots(3,2,figsize=(25,10),)

i,j = 0,0
for each in list_of_images:
    img = cv.imread(each.name)
    ax[i,j].imshow(img)
   

    if j == 1:
        j = 0
        if i != 2:
            i += 1
    else:
        j += 1

Example 4: matplotlib subplots

# First create some toy data:
x = np.linspace(0, 2*np.pi, 400)
y = np.sin(x**2)

# Creates just a figure and only one subplot
fig, ax = plt.subplots()
ax.plot(x, y)
ax.set_title('Simple plot')

# Creates two subplots and unpacks the output array immediately
f, (ax1, ax2) = plt.subplots(1, 2, sharey=True)
ax1.plot(x, y)
ax1.set_title('Sharing Y axis')
ax2.scatter(x, y)

# Creates four polar axes, and accesses them through the returned array
fig, axes = plt.subplots(2, 2, subplot_kw=dict(polar=True))
axes[0, 0].plot(x, y)
axes[1, 1].scatter(x, y)

# Share a X axis with each column of subplots
plt.subplots(2, 2, sharex='col')

# Share a Y axis with each row of subplots
plt.subplots(2, 2, sharey='row')

# Share both X and Y axes with all subplots
plt.subplots(2, 2, sharex='all', sharey='all')

# Note that this is the same as
plt.subplots(2, 2, sharex=True, sharey=True)

# Creates figure number 10 with a single subplot
# and clears it if it already exists.
fig, ax=plt.subplots(num=10, clear=True)
