How to set distance between bars in a horizontal bar diagram-CodePudding

I want to plot a bar diagram from a python counter.

toplist = countersum.most_common(len(countersum))
topkeylist = list()
topvallist = list()
for i in range(len(toplist)):
    topkeylist.append(toplist[i][0])
    topvallist.append(toplist[i][1])
for i in range(len(toplist)):
    print(topkeylist[i],":" ,topvallist[i])

keylist = list()
for key in topkeylist:
    keylist.append(str(key))

plt.barh(keylist[:100], topvallist[:100], height = 0.3, align = 'center')
plt.xlabel('Occurence inside the dataset')
plt.ylabel('N-gram sample')
plt.show()

It gives me the following plot:

I would like to set the spaces between bars so they can even touch and also align the text to the bar - as in the text size would be the same as the width of the bar to read it better.

CodePudding user response：

you can adjust the width of the bars by using the width parameter here:

plt.barh(keylist[:100], topvallist[:100], height = 0.3, align = 'center', width=5).

Also, try reducing the font size on the y-axis so that the tick marks are clearer:

plt.yticks(fontsize=10).

If this does not work, you can increase the size of the figure using

fig = plt.figure(figsize=(18,18))

You can set what you want in a dict and use
