条形图轴标签字体大小和间距

问题描述

我开发了图中的条形图，但是我的轴标签不可读。如何调整大小以使其可读？

%matplotlib inline
#create labels strings
country_labels = iso_code_var[pop1mill][sorted_top_20_deaths]
#Mortalitiy for each country
mortalities_bar = total_deaths_mil_var[pop1mill][sorted_top_20_deaths]
#create a bar plot
dummy = plt.bar(np.arange(len(country_labels)),mortalities_bar,width=bar_width,tick_label=country_labels)
#assign name for x axis
plt.xlabel('iso_code')
#assign name for y axis
plt.ylabel('total_deaths_per_million')
#assign name for the bar chart
plt.title('Mortality for Countries with 1 million + Population')
#display the plot
plt.show()

解决方法

您可以垂直旋转 xticks 使标签不重叠：plt.xticks(rotation='vertical')
