Matplotlib 是 Python 语言中最常用的绘图库之一,它提供了一整套用于制作静态、动态和交互式可视化的工具。无论你需要绘制简单的折线图还是复杂的三维图,Matplotlib 都能满足你的需求。 importmatplotlib.pyplotaspltimportnumpyasnp# 生成数据x=np.linspace(0,10,100)y=np.sin(x)# 绘制图形plt.plot(x,y)plt.tit...
# A配置:高分辨率保存plt.savefig('high_res_plot.png',dpi=600)# B配置:低分辨率保存plt.savefig('low_res_plot.png',dpi=72) 1. 2. 3. 4. 5. 深度原理 在图像保存的过程中,matplotlib会使用特定算法将绘图对象转化为图像文件,涉及到图像编码以及压缩等原理。 算法实现 通过对比不同版本的matplotlib,可...

In[1]:importmatplotlibimportmatplotlib.pyplotasplt Now to create and display a simple chart, we’ll first use the.plot()method and pass in a few arrays of numbers for our values. For this example, we’ll plot the number of books read over the span of a few months. In[2]: plt.plot...
