I am trying to fit a gilbrat PDF to a dataset (that I have in form of a list). I want to show the data in a histogram with a logarithmic x-scale and add the fitted curve. However, the curve seems too flat compared to the histogram, like in this picture: I tried to scale the pdf according to Fitting a Gaussian to a histogram with MatPlotLib and Numpy - wrong Y-scaling? , but the problem remains.
Here is a code example with randomly created data:
import scipy.stats as st
import numpy as np
import matplotlib.pyplot as plt
#create random dataset
data = st.gilbrat.rvs(scale = 10, size = 100).tolist()
param = st.gilbrat.fit(data)
x = np.linspace(min(data),max(data),len(data))
pdf = st.gilbrat.pdf(x, param[0], param[1])
plt.figure()
logbins = np.logspace(np.log10(np.min(data)),np.log10(np.max(data)),20)
result = plt.hist(data, bins=logbins, edgecolor="black", alpha = 0.5, label="data")
dx = result[1][1] - result[1][0]
plt.plot(x,pdf * (len(data)*dx), label="fit")
plt.xscale('log')
plt.xlabel("x")
plt.ylabel("Number of occurence")
plt.legend()
Am I missing something?
As your bins aren't equally spaced, the histogram isn't similar to a scaled version of the pdf. The bins at the right represent a much wider x-range than the ones at the left.
To predict the heights of the rectangles given the pdf, each bin region needs a different scaling factor, depending on the width of that bin.
The following code rescales each region independently, resulting in a discontinuously scaled pdf.
import scipy.stats as st
import numpy as np
import matplotlib.pyplot as plt
# create random dataset
np.random.seed(1)
data = st.gilbrat.rvs(scale=10, size=100)
param = st.gilbrat.fit(data)
x = np.logspace(np.log10(data.min()), np.log10(data.max()), 500)
pdf = st.gilbrat.pdf(x, param[0], param[1])
plt.figure()
logbins = np.logspace(np.log10(data.min()), np.log10(data.max()), 20)
heights, bins, rectangles = plt.hist(data, bins=logbins, edgecolor="black", alpha=0.5, label="data")
for b0, b1 in zip(bins[:-1], bins[1:]):
dx = b1 - b0
x_bin = np.logspace(np.log10(b0), np.log10(b1), 100)
pdf_bin = st.gilbrat.pdf(x_bin, param[0], param[1])
plt.plot(x_bin, pdf_bin * (len(data) * dx), color='crimson',
label="expected bin height" if b0 == bins[0] else None)
plt.xscale('log')
plt.xlabel("x")
plt.ylabel("Number of occurence")
plt.legend()
plt.tight_layout()
plt.show()
Here is another take, smoothing out the scaling of the pdf to any log-scale histogram. The dx is different at each x-position, in contrast to the histogram with linearly spaced bins.
import scipy.stats as st
import numpy as np
import matplotlib.pyplot as plt
# create random dataset
np.random.seed(1)
data = st.gilbrat.rvs(scale=10, size=100)
param = st.gilbrat.fit(data)
x = np.logspace(np.log10(data.min()), np.log10(data.max()), 500)
pdf = st.gilbrat.pdf(x, param[0], param[1])
plt.figure()
logbins = np.logspace(np.log10(data.min()), np.log10(data.max()), 20)
heights, bins, rectangles = plt.hist(data, bins=logbins, edgecolor="black", alpha=0.5, label="data")
dx_array = np.logspace(np.log10(bins[1] - bins[0]), np.log10(bins[-1] - bins[-2]), len(x))
plt.plot(x, pdf * len(data) * dx_array, color='crimson', label="pdf rescaled like histogram")
plt.xscale('log')
plt.xlabel("x")
plt.ylabel("Number of occurence")
plt.legend()
plt.tight_layout()
plt.show()
I want to plot some data x and y in which I need the marker size to depend on a third array z. I could plot them separately (i.e., scatter x and y with size = z, and errorbar without marker, fmc = 'none') and this solves it. The problem is that I need the legend to show the errorbar AND the dot, together:
and not
Code is here with some made-up data:
import matplotlib.pyplot as plt
import numpy as np
x = np.linspace(1,10,100)
y = 2*x
yerr = np.random(0.5,1.0,100)
z = np.random(1,10,100)
fig, ax = plt.subplots()
plt.scatter(x, y, s=z, facecolors='', edgecolors='red', label='Scatter')
ax.errorbar(x, y, yerr=yerr, xerr=0, fmt='none', mfc='o', color='red', capthick=1, label='Error bar')
plt.legend()
plt.show()
which produces the legend I want to avoid:
In errorbar the argumentmarkersizedoes not accept arrays asscatter` does.
The idea is usually to use a proxy to put into the legend. So while the errorbar in the plot may have no marker, the one in the legend has a marker set.
import matplotlib.pyplot as plt
import numpy as np
x = np.linspace(1,10,11)
y = 2*x
yerr = np.random.rand(11)*5
z = np.random.rand(11)*2+5
fig, ax = plt.subplots()
sc = ax.scatter(x, y, s=z**2, facecolors='', edgecolors='red')
errb = ax.errorbar(x, y, yerr=yerr, xerr=0, fmt='none',
color='red', capthick=1, label="errorbar")
proxy = ax.errorbar([], [], yerr=[], xerr=[], marker='o', mfc="none", mec="red",
color='red', capthick=1, label="errorbar")
ax.legend(handles=[proxy], labels=["errorbar"])
plt.show()
I am using matplotlib to make scatter plots. Each point on the scatter plot is associated with a named object. I would like to be able to see the name of an object when I hover my cursor over the point on the scatter plot associated with that object. In particular, it would be nice to be able to quickly see the names of the points that are outliers. The closest thing I have been able to find while searching here is the annotate command, but that appears to create a fixed label on the plot. Unfortunately, with the number of points that I have, the scatter plot would be unreadable if I labeled each point. Does anyone know of a way to create labels that only appear when the cursor hovers in the vicinity of that point?
It seems none of the other answers here actually answer the question. So here is a code that uses a scatter and shows an annotation upon hovering over the scatter points.
import matplotlib.pyplot as plt
import numpy as np; np.random.seed(1)
x = np.random.rand(15)
y = np.random.rand(15)
names = np.array(list("ABCDEFGHIJKLMNO"))
c = np.random.randint(1,5,size=15)
norm = plt.Normalize(1,4)
cmap = plt.cm.RdYlGn
fig,ax = plt.subplots()
sc = plt.scatter(x,y,c=c, s=100, cmap=cmap, norm=norm)
annot = ax.annotate("", xy=(0,0), xytext=(20,20),textcoords="offset points",
bbox=dict(boxstyle="round", fc="w"),
arrowprops=dict(arrowstyle="->"))
annot.set_visible(False)
def update_annot(ind):
pos = sc.get_offsets()[ind["ind"][0]]
annot.xy = pos
text = "{}, {}".format(" ".join(list(map(str,ind["ind"]))),
" ".join([names[n] for n in ind["ind"]]))
annot.set_text(text)
annot.get_bbox_patch().set_facecolor(cmap(norm(c[ind["ind"][0]])))
annot.get_bbox_patch().set_alpha(0.4)
def hover(event):
vis = annot.get_visible()
if event.inaxes == ax:
cont, ind = sc.contains(event)
if cont:
update_annot(ind)
annot.set_visible(True)
fig.canvas.draw_idle()
else:
if vis:
annot.set_visible(False)
fig.canvas.draw_idle()
fig.canvas.mpl_connect("motion_notify_event", hover)
plt.show()
Because people also want to use this solution for a line plot instead of a scatter, the following would be the same solution for plot (which works slightly differently).
import matplotlib.pyplot as plt
import numpy as np; np.random.seed(1)
x = np.sort(np.random.rand(15))
y = np.sort(np.random.rand(15))
names = np.array(list("ABCDEFGHIJKLMNO"))
norm = plt.Normalize(1,4)
cmap = plt.cm.RdYlGn
fig,ax = plt.subplots()
line, = plt.plot(x,y, marker="o")
annot = ax.annotate("", xy=(0,0), xytext=(-20,20),textcoords="offset points",
bbox=dict(boxstyle="round", fc="w"),
arrowprops=dict(arrowstyle="->"))
annot.set_visible(False)
def update_annot(ind):
x,y = line.get_data()
annot.xy = (x[ind["ind"][0]], y[ind["ind"][0]])
text = "{}, {}".format(" ".join(list(map(str,ind["ind"]))),
" ".join([names[n] for n in ind["ind"]]))
annot.set_text(text)
annot.get_bbox_patch().set_alpha(0.4)
def hover(event):
vis = annot.get_visible()
if event.inaxes == ax:
cont, ind = line.contains(event)
if cont:
update_annot(ind)
annot.set_visible(True)
fig.canvas.draw_idle()
else:
if vis:
annot.set_visible(False)
fig.canvas.draw_idle()
fig.canvas.mpl_connect("motion_notify_event", hover)
plt.show()
In case someone is looking for a solution for lines in twin axes, refer to How to make labels appear when hovering over a point in multiple axis?
In case someone is looking for a solution for bar plots, please refer to e.g. this answer.
This solution works when hovering a line without the need to click it:
import matplotlib.pyplot as plt
# Need to create as global variable so our callback(on_plot_hover) can access
fig = plt.figure()
plot = fig.add_subplot(111)
# create some curves
for i in range(4):
# Giving unique ids to each data member
plot.plot(
[i*1,i*2,i*3,i*4],
gid=i)
def on_plot_hover(event):
# Iterating over each data member plotted
for curve in plot.get_lines():
# Searching which data member corresponds to current mouse position
if curve.contains(event)[0]:
print("over %s" % curve.get_gid())
fig.canvas.mpl_connect('motion_notify_event', on_plot_hover)
plt.show()
From http://matplotlib.sourceforge.net/examples/event_handling/pick_event_demo.html :
from matplotlib.pyplot import figure, show
import numpy as npy
from numpy.random import rand
if 1: # picking on a scatter plot (matplotlib.collections.RegularPolyCollection)
x, y, c, s = rand(4, 100)
def onpick3(event):
ind = event.ind
print('onpick3 scatter:', ind, npy.take(x, ind), npy.take(y, ind))
fig = figure()
ax1 = fig.add_subplot(111)
col = ax1.scatter(x, y, 100*s, c, picker=True)
#fig.savefig('pscoll.eps')
fig.canvas.mpl_connect('pick_event', onpick3)
show()
This recipe draws an annotation on picking a data point: http://scipy-cookbook.readthedocs.io/items/Matplotlib_Interactive_Plotting.html .
This recipe draws a tooltip, but it requires wxPython:
Point and line tooltips in matplotlib?
The easiest option is to use the mplcursors package.
mplcursors: read the docs
mplcursors: github
If using Anaconda, install with these instructions, otherwise use these instructions for pip.
This must be plotted in an interactive window, not inline.
For jupyter, executing something like %matplotlib qt in a cell will turn on interactive plotting. See How can I open the interactive matplotlib window in IPython notebook?
Tested in python 3.10, pandas 1.4.2, matplotlib 3.5.1, seaborn 0.11.2
import matplotlib.pyplot as plt
import pandas_datareader as web # only for test data; must be installed with conda or pip
from mplcursors import cursor # separate package must be installed
# reproducible sample data as a pandas dataframe
df = web.DataReader('aapl', data_source='yahoo', start='2021-03-09', end='2022-06-13')
plt.figure(figsize=(12, 7))
plt.plot(df.index, df.Close)
cursor(hover=True)
plt.show()
Pandas
ax = df.plot(y='Close', figsize=(10, 7))
cursor(hover=True)
plt.show()
Seaborn
Works with axes-level plots like sns.lineplot, and figure-level plots like sns.relplot.
import seaborn as sns
# load sample data
tips = sns.load_dataset('tips')
sns.relplot(data=tips, x="total_bill", y="tip", hue="day", col="time")
cursor(hover=True)
plt.show()
The other answers did not address my need for properly showing tooltips in a recent version of Jupyter inline matplotlib figure. This one works though:
import matplotlib.pyplot as plt
import numpy as np
import mplcursors
np.random.seed(42)
fig, ax = plt.subplots()
ax.scatter(*np.random.random((2, 26)))
ax.set_title("Mouse over a point")
crs = mplcursors.cursor(ax,hover=True)
crs.connect("add", lambda sel: sel.annotation.set_text(
'Point {},{}'.format(sel.target[0], sel.target[1])))
plt.show()
Leading to something like the following picture when going over a point with mouse:
A slight edit on an example provided in http://matplotlib.org/users/shell.html:
import numpy as np
import matplotlib.pyplot as plt
fig = plt.figure()
ax = fig.add_subplot(111)
ax.set_title('click on points')
line, = ax.plot(np.random.rand(100), '-', picker=5) # 5 points tolerance
def onpick(event):
thisline = event.artist
xdata = thisline.get_xdata()
ydata = thisline.get_ydata()
ind = event.ind
print('onpick points:', *zip(xdata[ind], ydata[ind]))
fig.canvas.mpl_connect('pick_event', onpick)
plt.show()
This plots a straight line plot, as Sohaib was asking
mpld3 solve it for me.
EDIT (CODE ADDED):
import matplotlib.pyplot as plt
import numpy as np
import mpld3
fig, ax = plt.subplots(subplot_kw=dict(axisbg='#EEEEEE'))
N = 100
scatter = ax.scatter(np.random.normal(size=N),
np.random.normal(size=N),
c=np.random.random(size=N),
s=1000 * np.random.random(size=N),
alpha=0.3,
cmap=plt.cm.jet)
ax.grid(color='white', linestyle='solid')
ax.set_title("Scatter Plot (with tooltips!)", size=20)
labels = ['point {0}'.format(i + 1) for i in range(N)]
tooltip = mpld3.plugins.PointLabelTooltip(scatter, labels=labels)
mpld3.plugins.connect(fig, tooltip)
mpld3.show()
You can check this example
mplcursors worked for me. mplcursors provides clickable annotation for matplotlib. It is heavily inspired from mpldatacursor (https://github.com/joferkington/mpldatacursor), with a much simplified API
import matplotlib.pyplot as plt
import numpy as np
import mplcursors
data = np.outer(range(10), range(1, 5))
fig, ax = plt.subplots()
lines = ax.plot(data)
ax.set_title("Click somewhere on a line.\nRight-click to deselect.\n"
"Annotations can be dragged.")
mplcursors.cursor(lines) # or just mplcursors.cursor()
plt.show()
showing object information in matplotlib statusbar
Features
no extra libraries needed
clean plot
no overlap of labels and artists
supports multi artist labeling
can handle artists from different plotting calls (like scatter, plot, add_patch)
code in library style

Giving the following result:
Maybe this helps anybody, but I have adapted the #ImportanceOfBeingErnest's answer to work with patches and classes. Features:
The entire framework is contained inside of a single class, so all of the used variables are only available within their relevant scopes.
Can create multiple distinct sets of patches
Hovering over a patch prints patch collection name and patch subname
Hovering over a patch highlights all patches of that collection by changing their edge color to black
Note: For my applications, the overlap is not relevant, thus only one object's name is displayed at a time. Feel free to extend to multiple objects if you wish, it is not too hard.
