. Show () Note Here the Chinese must use U (3.0 above as if not, I use 2.7), because matplotlib only support Unicode. Next, let's describe each bar on the x-axis. For example, the first one is "male" and the second is "female". Import Matplotlib.pyplot as Plt plt.xlabel (U ' sex ') Plt.ylabel (U ' number ') plt.xticks ((0,1), (U ' male ', U ' Female ')) Plt.bar (left = (0,1), Height = (1,0.5), width = 0

The reason for a paper recently, to get some data from Excel to draw, but the resulting figure is a bitmap, not too good to insert into the paper, so decided to use Python paint to solve this problem (not using MATLAB because it is the picture is not good-looking) The first library to use is the XLRD library, which functions from reading Excel data #对应的所有例子中使用的方法贴到了文章最后, easy to find import xlrd #首先实例化一个book对象 book = Xlrd.open_workbook ("One Excel Address") # Then get all the sheet names for thi
