ডিক থেকে সরাসরি ডেটা ব্যবহার করে কোনও বার প্লট প্লট করার কোনও উপায় আছে কি ?
আমার আদেশটি এরকম দেখাচ্ছে:
D = {u'Label1':26, u'Label2': 17, u'Label3':30}
আমি আশা করেছিলাম
fig = plt.figure(figsize=(5.5,3),dpi=300)
ax = fig.add_subplot(111)
bar = ax.bar(D,range(1,len(D)+1,1),0.5)
কাজ, কিন্তু এটি না।
ত্রুটি এখানে:
>>> ax.bar(D,range(1,len(D)+1,1),0.5)
