Examples
Some usage examples and ways to make the figure better than what default options yield.
First import stuff

A very simple example also shown in the wiki to simply introduce the call signature of adjust_text
[2]:
np.random.seed(0)
x, y = np.random.random((2,30))
fig, ax = plt.subplots()
plt.plot(x, y, 'bo')
texts = [plt.text(x[i], y[i], 'Text%s' %i, ha='center', va='center') for i in range(len(x))]
[3]:
np.random.seed(0)
x, y = np.random.random((2,30))
fig, ax = plt.subplots()
plt.plot(x, y, 'bo')
texts = [ax.text(x[i], y[i], 'Text%s' %i, ha='center', va='center') for i in range(len(x))]
adjust_text(texts);
[4]:
fig, ax = plt.subplots()
ax.plot(x, y, 'bo')
texts = [ax.text(x[i], y[i], 'Text%s' %i, ha='center', va='center') for i in range(len(x))]
adjust_text(texts, expand=(1.2, 2), # expand text bounding boxes by 1.2 fold in x direction and 2 fold in y direction
arrowprops=dict(arrowstyle='->', color='red') # ensure the labeling is clear by adding arrows
);
First a very simple example with labelling one point out of many
[5]:
def plot_scatter(adjust=False):
np.random.seed(100)
x, y = np.random.random((2,400))
fig, ax = plt.subplots()
ax.plot(x, y, 'bo')
texts = [plt.text(x[0], y[0], 'Something')]
if adjust:
texts, patches = adjust_text(texts, x=x, y=y, expand=(1.1, 1.5), arrowprops=dict(arrowstyle='->', color='red'))
plot_scatter();
As you can see, the label overlaps many points here and it is difficult to understand what it says. Also it is not clear which of the points it corresponds to. Let’s try to asjust its location with default parameters while adding an arrow to connect it to the original point.
[6]:
plot_scatter(adjust=True);
Here the number we see in the output is number of iteration the algorithm used to adjust the location of the text. The result is much better! The text doesn’t overlap anything and is legible while clearly corresponding to one particular point.
A very simple example from http://stackoverflow.com/q/19073683/1304161, but I’ll show some special tricks with it
First let’s just create the data and plot it with no adjustment or anything. Then I will show how to restrict movement along one of the axes, repel text from the lina and some logic behind potential adjustment of parameters to make your plot look nicer.
[7]:
together = [(0, 1.0, 0.4), (25, 1.0127692669427917, 0.41), (50, 1.016404709797609, 0.41), (75, 1.1043426359673716, 0.42), (100, 1.1610446924342996, 0.44), (125, 1.1685687930691457, 0.43), (150, 1.3486407784550272, 0.45), (250, 1.4013999168008104, 0.45)]
together.sort()
text = [x for (x,y,z) in together]
eucs = [y for (x,y,z) in together]
covers = [z for (x,y,z) in together]
def plot_eucs_covers():
plt.plot(eucs,covers,color="black", alpha=0.5)
texts = []
for xt, yt, s in zip(eucs, covers, text):
texts.append(plt.text(xt, yt, s, ha='center', va='center'))
return texts
plot_eucs_covers();
Now let’s just apply the text adjustment with all default parameters and define the arrow properties we like.
[8]:
texts = plot_eucs_covers()
adjust_text(texts, arrowprops=dict(arrowstyle="->", color='r', lw=0.5));
Now one of the labels overlays the line and two are very close to it, that’s not pretty. We’ll create some virtual points along the lines using linear interpolation to repel the labels from the graph itself.
[9]:
from scipy import interpolate
texts = plot_eucs_covers()
f = interpolate.interp1d(eucs, covers)
x = np.linspace(min(eucs), max(eucs), 300)
y = f(x)
adjust_text(texts, x=x, y=y, arrowprops=dict(arrowstyle="->", color='r', lw=0.5));
Now this is quite good! Making the distance of labels to the line exactly right is difficult because of the artificial way we are repelling them and different shape of the line close to different labels.
Now a real-world example of a volcano plot
(idea and data from http://www.gettinggeneticsdone.com/2016/01/repel-overlapping-text-labels-in-ggplot2.html)
First let’s just plot the data
[10]:
data = pd.read_csv('../../figures/volcano_data.csv')
def plot_volcano(adjust=False, **kwargs):
plt.figure(figsize=(7, 10))
threshold = 0.05
xns, yns = data['log2FoldChange'][data['padj']>=threshold], -np.log10(data['pvalue'][data['padj']>=threshold])
plt.scatter(xns, yns, c='grey', edgecolor=(1,1,1,0), label='Not Sig')
xs, ys = data['log2FoldChange'][data['padj']<threshold], -np.log10(data['pvalue'][data['padj']<threshold])
plt.scatter(xs, ys, c='r', edgecolor=(1,1,1,0), label='FDR<5%')
texts = []
for x, y, l in zip(xs, ys, data['Gene'][data['padj']<threshold]):
texts.append(plt.text(x, y, l, size=8, ha='center', va='center'))
plt.legend()
plt.xlabel('$log_2(Fold Change)$')
plt.ylabel('$-log_{10}(pvalue)$')
if adjust:
adjust_text(texts,
arrowprops=dict(arrowstyle="-", color='k', lw=0.5), **kwargs)
plot_volcano();
We can’t read half of the labels in the left half! Let’s adjust them :)
[11]:
plot_volcano(adjust=True);
And this is very nice now!
Now a classical mtcars dataset; example from ggrepel package for R
[12]:
mtcars = pd.read_csv('../../figures/mtcars.csv')
def plot_mtcars(adjust=False, *args, **kwargs):
plt.figure(figsize=(9, 6))
plt.scatter(mtcars['wt'], mtcars['mpg'], s=15, c='r', edgecolors=(1,1,1,0))
texts = []
for x, y, s in zip(mtcars['wt'], mtcars['mpg'], mtcars['Car']):
texts.append(plt.text(x, y, s, size=9, ha='center', va='center'))
plt.xlabel('wt')
plt.ylabel('mpg')
if adjust:
adjust_text(texts, arrowprops=dict(arrowstyle="-", color='k', lw=0.5))
plot_mtcars();
Aaa everything is overlapping!!! Crazy. Let’s fix it.
[13]:
plot_mtcars(adjust=True);
Now this is pretty good!
Note that I specified the figure size for two latter examples. Obviously, making it larger is one of the easiest ways to reduce overlaps, but often it is limited - that’s when this library can help!
Now an example from https://blog.mafr.de/2012/03/11/time-series-data-with-matplotlib/ with adding labels
[14]:
import matplotlib.dates as mdates
import locale
# locale.setlocale(locale.LC_ALL,'en_US.utf8') #I have it set to Russian, without this dates don't work
[15]:
impressions = pd.read_table("../../figures/page-impressions.csv", names=['days', 'impressions'])
impressions['days'] = pd.to_datetime(impressions['days'])
[16]:
def plot_dates(adjust=False):
plt.figure(figsize=(10, 7))
plt.plot_date(x=impressions['days'], y=impressions['impressions'])
texts = []
for i, (x, y) in impressions.iterrows():
texts.append(plt.text(x, y, int(y)))
if adjust:
adjust_text(texts, arrowprops=dict(arrowstyle="->", color='r', lw=0.5))
plot_dates(adjust=False);
[17]:
plot_dates(adjust=True);
Labelling bars above them
It is possible to repel labels from any additional matplotlib objects, in this case bars, but can also be a legend, for example. Note, that the objects’ bounding boxes are used, with a bounding box being the smallest rectangle contataining the object.
[18]:

rect.set_facecolor('red')
# Now adjust the text. We don't want to move in the x direction and we want the labels to vertically aligned with the bars.
# I also noticed that having a weaker force to repel texts from ech other makes the figure nicer.
ax.set_ylabel('CA')
adjust_text(texts, add_objects=bars,

Looks nice! I guess it can be quite a common use case.
Difficult examples
Now a couple very nice real-world plots using data from universaldependencies.org v2.2 by Kim Gerdes. This is something about the prevalence of particular syntactic structures in different languages, which are colour-coded by their language group. You can see how languages of some groups are very nicely clustered together! It is really dense in some areas, so we increase the time limit for the algorithm to 1 second, instead of default 0.1 second. No other parameter adjustment necessary to get very decent results!

adjust_text(texts, ax=ax,

We can also look at distribution of languages across just one of these features, and we can use adjust_text to nicely arrange the labels along one axis.
