在Matplotlib中,我们可以使用ax.invert_xaxis()方法或设置xlim来实现这一目的。 2.1 使用ax.invert_xaxis()方法 这是最简单直接的方法,只需要在绘图后调用ax.invert_xaxis()即可。 importmatplotlib.pyplotaspltimportnumpyasnp# 创建数据x=np.linspace(0,10,100)y=np.sin(x)# 创建图形和坐标轴fig,ax=plt....
max(x), 10,endpoint=True),2) h = plt.hist(x, bins=bins, color='navy', edgecolor='white',alpha=0.5) plt.xlabel('value',) plt.ylabel('frequency', rotation='horizontal',y=1) plt.xticks(bins, bins) plt.grid(axis='y',linewidth=0.5,linestyle='--') # 网格线 plt.show()...
importmatplotlib.pyplotasplt# 创建数据x=range(5)y1=[1,3,2,4,3]y2=[2,4,3,5,4]# 绘制图表plt.plot(x,y1,label='Series 1 - how2matplotlib.com')plt.plot(x,y2,label='Series 2 - how2matplotlib.com')# 添加图例plt.legend()plt.title('Basic Plot with Legend')plt.xlabel('X-axis')...
接着就是获取计数结果中的键和对应的值分别组成x和对应的y,Counter中有一个函数可以获得前十名的计数内容:most_common(10),括号中的数值可以自行指定 至此绘制图形需要的x和y的数据就准备完毕,绘图如下 2.2.2 处理x轴标签过密问题 针对...

The xlims and ylims functions are used to set limits on the values along the axes. Now we can use our logic to invert the axes. The function takes a list-like object. If we reverse the data points and pass them to the function, the data points along the axes will be inverted. ...

11. plt.axis([array]),array内数字依次代表xmin, xmax, ymin, ymax。 12. import numpy as np——也不错,沿用之。np.arange()跟range()差不多,不过参数可以用小数,返回的也是一个array啦。 13. 设置线条属性。a. 参见9;b. plt.plot()返回matplotlib.lines.line2D实例,可使用相应的类方法;c. plot...
