The Plot I Want to Fix
I am trying to graph three graphs stacked on top of each other and for the most part it works fine.
However when I add a colorbar to the last spectogram plot it completely squishes the plot, making the overall figure ugly.... How do I fix this?
fig, ax = plt.subplots(3, sharex=True, figsize=(50, 10))
fig.suptitle('Test' + str("%03d" % (i,)) + '+ Noisereduce', fontsize=48)
ax[0].plot(time, raw, color='blue')
ax[0].plot(time, fltr, color='orange')
ax[0].set_title('Raw Signal')
ax[1].plot(time, fltr, color='orange')
ax[1].set_title('noisereduce (stationary filter)')
spect = ax[2].pcolormesh(t, f, 10*np.log10(Sxx), vmin=vmin, vmax=vmax, shading='gouraud')
ax[2].set(xlabel='Time [sec]', ylabel='Frequency [Hz]')
fig.colorbar(spect, ax=ax[2])
ax[2].set_title('noisereduce - spectogram (upper 67% of intensities)')
plt.show()

Python Matplotlib pyplot histogram
(3 answers)
Closed 4 months ago.
I am making a histogram using matplotlib. I am using integer data and I want them to represent 1 bin. The following is the sample code which I made.
import matplotlib.pyplot as plt
a=[1,2,2,3,3,3,4,4,4,4]
plt.figure()
plt.hist(a,bins=4)
plt.show()
The histogram which I got is above. This have left end 1 ad rightend 4. I want the width of the histogram to be 1, however, this will just show 0.75 size. Moreover, I want the x value to locate at the center of the bar of histogram. Is there any way I can adjust?

There are a few examples showing how to use "shrink" for changing the colorbar. How can I automatically figure out what the shrink should be so the colorbar is equal to the height of the heatmap?
I don't have a matplotlib axis because I am using seaborn and plotting the heatmap from the dataframe.
r = []
r.append(np.arange(0,1,.1))
r.append(np.arange(0,1,.1))
r.append(np.arange(0,1,.1))
df_cm = pd.DataFrame(r)
sns.heatmap(df_cm, square=True, cbar_kws=dict(ticks=[df_cm.min().min(), df_cm.max().max()]))
plt.tight_layout()
plt.savefig(f'test.png', bbox_inches="tight")

Move seaborn plot legend to a different position

Closed 3 months ago.
In countplot legend for hue are placed at improper positition:
sns.countplot(x='cat114', hue='loss', data=data_tr)
How do I change legend position?
I tried plt.legend(loc='upper right') but it is not helping me.
g=sns.countplot(x=feature, hue='loss', data=data_tr)
g.figure.get_axes()[0].legend(title='loss',loc='upper right')

Getting legend in seaborn jointplot
(2 answers)
Closed 3 years ago.
When generating bivariate plots like hexbin, pandas generates a legend explaining frequency value for each color shade:
pokemon.plot.hexbin(x='HP', y='Attack', gridsize=30)
I cannot find a similar way to generate such a legend for jointplot and kdeplot in seaborn:
sns.jointplot(data=pokemon, x='HP', y='Attack', kind='hex')
sns.kdeplot(pokemon['HP'], pokemon['Attack'], shade=True)
How can I do it?
for a kdeplot, simply pass cbar=True
cbar : bool, optional
If True and drawing a bivariate KDE plot, add a colorbar.
