How to plot Horizontal bar graph from a dictionary using matplotlib?

Question

I am using:

plt.bar(range(len(d)), d.values(), align='center')
plt.yticks(range(len(d)), d.keys())
plt.xlabel('frequency', fontsize=18)
plt.ylabel('keywords', fontsize=18)

plt.show()

and I am getting the output below: enter image description here

but I want to show the corresponding bar for each keyword on the y-axis, rather than the x-axis. How can I achieve that?

It looks like you are setting yticks the keys of the dictionary. Maybe you want to do that for xticks? — Uğur Güney

But then it will plot keywords on x-axis. I have to plot keywords on y-axis and corresponding horizontal bar with corresponding values on x-axis. — shobhit kumar

Using matplotlib's barh() function will create a horizontal bar chart for you:

plt.barh(range(len(d)), d.values(), align='center')

From the docs:

matplotlib.pyplot.barh(bottom, width, height=0.8, left=None, hold=None, **kwargs)

Make a horizontal bar plot with rectangles bounded by:

left, left + width, bottom, bottom + height

(left, right, bottom and top edges)

bottom, width, height, and left can be either scalars or sequences

Also see the barh demo on the matplotlib gallery page here

Use plt.barh() rather than using the vertical bar chart function.
