今天想直观的展示一下数据就用到了matplotlib模块,之前都是一张图只有一条曲线,现在想同一个图片上绘制多条曲线来对比,实现很简单,具体如下:
1

10
11
12

for j in range ( len (mat)):
one_list.append(mat[j][i])
res.append(one_list)

data_list = []
for i in range ( 100 ):
data_list.append(random.randint( 2 , 150 ))
month_list = range ( 1 , 11 , 1 )
mat = list2mat(data_list,w = 10 )
for one_list in mat:
one_list = [ int (one) for one in one_list]
plt.plot(month_list,one_list, "x-" ,label = "test_zhexian" )
plt.savefig( 'test_zhexian.png' )
plt.close()
for one_list in mat:
one_list = [ int (one) for one in one_list]
plt.scatter(month_list,one_list,marker = 'x' ,label = 'test_sandian' ,s = 30 )
plt.savefig( 'test_sandian.png' )
plt.close()
if __name__ = = '__main__' :
draw_pic_test()

结果如下:
1.折线图
2.散点图
挺有意思的。
