import matplotlib.pyplot as plt plt.hist(x = '需要处理的数据',bins = '需要分割的精度') plt.xlabel('x轴标签') plt.ylabel('y轴标签') plt.title('总标题') plt.show() bins? 按照我的个人实验结果,应该是关于精度的变量,跟组数无关 不妨bins = 10 or 100 or 120 or 1200对比观察一下 以...
If bins is a string, it is one of the binning strategies supported bynumpy.histogram_bin_edges: 'auto', 'fd', 'doane', 'scott', 'stone', 'rice', 'sturges', or 'sqrt'. 我来概括一下,也就是说如果bins是个数字,那么它设置的是bin的个数,也就是沿着x轴划分多少个独立的绘图区域。我们这...
通过一个简单的实例来演示如何在PyTorch中使用bins参数。 importtorchimportmatplotlib.pyplotasplt# 生成一组随机数据data=torch.randn(1000)# 生成直方图hist=torch.histc(data,bins=20,min=-3,max=3)# 绘制直方图plt.figure(figsize=(10,6))plt.bar(torch.arange(20),hist.numpy(),width=0.8,color='lightblue...
#img.ravel() 将图像转成一维数组,这里没有中括号。 hist,bins = np.histogram(img.ravel(),256,[0,256]) 1. 2. 绘制直方图: 有两种方法来绘制直方图: Short Way(简单方法):使用 Matplotlib 中的绘图函数。 Long Way(复杂方法):使用 OpenCV 绘图函数 import cv2 from matplotlib import pyplot as plt im...
label=["Client {}".format(i)foriinrange(N_CLIENTS)]) 修改之后的图表如下: 可以看到每个x轴元素内的bar正好占对应bin的宽度的二分之一。 引用 [1] https://matplotlib.org/stable/api/_as_gen/matplotlib.pyplot.hist.html 到此这篇关于Matplotlib直方图绘制中的参数bins和rwidth的实现的文章就介绍到这了...

wanted to gauge interest in adding a method to Classifier that plots the histogram of y with class bins a la desktop GIS pandas and seaborn are optional dependencies but usually available in a pysal environment. If we take the coloring logic from #211 I think the legendgram could also be ...
