2023-08-01 python根据x轴、y轴坐标（数组）在坐标轴里画出曲线图，python 会调用鼎鼎大名的matlib，用来分析dac 数据
一、python 源码如下
import numpy as np
import matplotlib as mpl
import matplotlib.pyplot as plt
#x=[0 ,1,2,3,5,6,10]
#y=[0,0,3,4,5,7,8]
# { 0 , 1 , 0x0003 },// 0
# { 0XFFFF * 1 / 10 , 3006 , 0x0a6b },// 1
# { 0XFFFF * 2 / 10 , 5997 , 0x14c5 },// 2
# { 0XFFFF * 3 / 10 , 8992 , 0x1f22 },// 3
# { 0XFFFF * 4 / 10 , 11991 , 0x2983 },// 4
# { 0XFFFF * 5 / 10 , 14988 , 0x33e3 },// 5
# { 0XFFFF * 6 / 10 , 17986 , 0x3e42 },// 6
# { 0XFFFF * 7 / 10 , 20983 , 0x48a2 },// 7
# { 0XFFFF * 8 / 10 , 23980 , 0x5302 },// 8
# { 0XFFFF * 9 / 10 , 26978 , 0x5d61 },// 9
# { 0XF300 , 28453
x=[0,0XFFFF * 1 / 10,0XFFFF * 2 / 10,0XFFFF * 3/ 10,0XFFFF * 4/ 10,0XFFFF * 5/ 10,0XFFFF * 6/ 10,0XFFFF * 7/ 10,0XFFFF * 8/ 10,0XFFFF * 9 / 10,0XF300]
#y=[1,3006,5997,8992,11991,14988,17986,20983,23980,26978,28453]
y=[1,3006,5997,8992,11991,14988,17986,20983,23980,26978,28453]
c=[0,0XF300]
d=[1,28453]
mpl.rcParams['figure.facecolor'] = 'silver'
plt.rcParams['axes.facecolor'] = 'silver'
ax = plt.gca()
#去掉边框
#ax.spines['top'].set_color('none')
#ax.spines['right'].set_color('none')
#移位置 设为原点相交
ax.xaxis.set_ticks_position('bottom')
ax.spines['bottom'].set_position(('data',0))
ax.yaxis.set_ticks_position('left')
ax.spines['left'].set_position(('data',0))
plt.title('Title')
plt.plot(c, d, linewidth = 1.0,color='red', label='test2')
plt.plot(x, y,linewidth = 1.0, color='blue', label='test1')
plt.plot(x, y, 'om')
plt.legend() # 显示图例
plt.xticks(range(0, 0XF300, 5000))
plt.xticks(rotation = 90)
plt.yticks(range(0, 30000, 5000))
plt.axis('equal')
plt.xlabel('X')
plt.ylabel('Y')
#plt.savefig("C:/Users/Watson/Desktop/test.jpg")
plt.show()
