想把python提取出来的 加载点反力和某个单元的应力画在同一个XY曲线图上，由于两者数量级差太远，故而需要建立有两个Y轴的XY曲线图。
效果为：
代码如下：
Quatype1=xyPlot.QuantityType(label='应力' , type=STRESS)
Quatype2=xyPlot.QuantityType(label='荷载' , type=FORCE)
Quatype3=xyPlot.QuantityType(label='时间' , type=TIME)
fileName1='D:SaveDataTestLoad-Time.txt'
file = open(fileName1)
lines = file.readlines()
file.close()
pxy = lines[0].split(',')
pxy = [x.strip() for x in pxy]
plotName, xAxisTitle, yAxisTitle = pxy
data = []
for line in lines[1:]:
line=line.replace('t' , ',')
data.append(eval(line))
xyData1 = session.XYData(name='cv1', data=data, contentDescription=fileName1,
axis1QuantityType=Quatype3, axis2QuantityType=Quatype2)
curve1 = session.Curve(xyData1)
fileName2='D:SaveDataTestRF-Mises-Time-N01.txt'
file = open(fileName2)
lines = file.readlines()
file.close()
pxy = lines[0].split(',')
pxy = [x.strip() for x in pxy]
plotName, xAxisTitle, yAxisTitle = pxy
while plotName in session.xyPlots.keys():
plotName=plotName+'-1'
data = []
for line in lines[1:]:
line=line.replace('t' , ',')
data.append(eval(line))
xyData2 = session.XYData(name='cv2', data=data, contentDescription=fileName2,
axis1QuantityType=Quatype3, axis2QuantityType=Quatype1)
curve2 = session.Curve(xyData2)
xyList=[xyData1,xyData2,]
curveList = session.curveSet(xyData=xyList)
xyPlot = session.XYPlot(plotName)
chart = xyPlot.charts.values()[0]
chart.setValues(curvesToPlot=curveList)
用于提取数据的两个文件，内容如下：
