I would like to add y-axis values to my plot but am unsure how to.
The plot is displayed below:
The code used to generate the plot is given below:
pd.options.display.float_format = "{:,.0f}".format
DATE_PERIOD = WORLDWIDE_COVID19_DATASET_TOTAL["DATE"]
MONTHLY_NUMBER_OF_CASES = WORLDWIDE_COVID19_DATASET_TOTAL["TOTAL NUMBER OF COVID-19 CASES"]
fig = plt.figure(figsize = (48, 20))
plt.plot(DATE_PERIOD, MONTHLY_NUMBER_OF_CASES, color = "#4b0082")
plt.title("TRENDLINE OF THE TOTAL NUMBER OF COVID-19 CASES WORLDWIDE FROM JANUARY 2020 TO JULY 2020", fontsize = 24)
plt.xlabel("DATE PERIOD (JANUARY 2020 TO JULY 2020)", fontsize = 20)
plt.ylabel("TOTAL NUMBER OF COVID-19 CASES WORLDWIDE", fontsize = 20)
plt.xticks(fontsize = 18)
plt.yticks(fontsize = 18)
ax = plt.gca()
ax.yaxis.set_major_formatter(mticker.ScalarFormatter())
ax.yaxis.get_major_formatter().set_scientific(False)
ax.yaxis.get_major_formatter().set_useOffset(False)
plt.show()
As such, how can I add y-axis only values?
Also, can I edit the y-axis only value' font size, type and boldness?
Many thanks!
what do you mean by how can I add y-axis only values?
you can add more values to panda dataframe column MONTHLY_NUMBER_OF_CASES
and yes you can edit the y-axis only value' font size, type and boldness.
If you're using seaborn
then direct use the feature sns.set(font_scale=3)
.
import seaborn as sns
import matplotlib.pyplot as plt
flights = sns.load_dataset("flights")
flights.head()
may_flights = flights.query("month == 'May'")
sns.set(font_scale=1.5) # crazy big this will change font for all the figure
# or use this
g = sns.lineplot(data=may_flights, x="year", y="passengers", lw=3)
g.axes.set_title("Title",fontsize=50)
g.set_xlabel("X Label",fontsize=30)
g.set_ylabel("Y Label",fontsize=20)
g.tick_params(labelsize=20)
Thanks for the help and advice. I believe I was not explicit enough in presenting my query.
However, I managed to find an answer on own.
The plot is supposed to look like this:
I obtained this plot from a "for loop".
The "for loop" is required to generate the annotations for the y-axis values on the plot.
The code is given as:
# Displaying the trendline of the total number of COVID-19 cases worldwide from January 2020 to July 2020.
# Displaying all numbers to 0 decimal places
pd.options.display.float_format = "{:,.0f}".format
DATE_PERIOD = WORLDWIDE_COVID19_DATASET_TOTAL["DATE"]
MONTHLY_NUMBER_OF_CASES = WORLDWIDE_COVID19_DATASET_TOTAL["TOTAL NUMBER OF COVID-19 CASES"]
fig = plt.figure(figsize = (48, 20))
plt.plot(DATE_PERIOD, MONTHLY_NUMBER_OF_CASES, color = "#4b0082")
plt.title("TRENDLINE OF THE TOTAL NUMBER OF COVID-19 CASES WORLDWIDE FROM JANUARY 2020 TO JULY 2020", fontsize = 24)
for x, y in zip(DATE_PERIOD, MONTHLY_NUMBER_OF_CASES):
label = "{:.0f}".format(y)
plt.annotate(label, # this is the text
(x, y), # this is the point to label
fontsize = 22, # this is the label font size
textcoords = "offset points", # how to position the text
xytext = (0, 10), # distance from text to points (x,y)
ha = "right") # horizontal alignment can be left, right or center
plt.xlabel("DATE PERIOD (JANUARY 2020 TO JULY 2020)", fontsize = 20)
plt.ylabel("TOTAL NUMBER OF COVID-19 CASES WORLDWIDE", fontsize = 20)
plt.xticks(fontsize = 18)
plt.yticks(fontsize = 18)
ax = plt.gca()
ax.yaxis.set_major_formatter(mticker.ScalarFormatter())
ax.yaxis.get_major_formatter().set_scientific(False)
ax.yaxis.get_major_formatter().set_useOffset(False)
plt.show()
