1、用ORIGIN6.0设置数据图的基线1、去本底：选择toolsàbaseline2、出现下面的窗口，选择baseline，将numberofpoints后的参数改小一些，比如2，点击createbaseline3、出现下图：选择小窗口中的modify：Secretarymusttreeprison"grasppartyisjob,notcaughtpartyisderelictionof,caughtbadpartyisnotcompetent"ofconsciousness,effectiveperformcaughtpartyfirstresponsibilitypeopledutie
2、s,seriouslyimplementationgrass-rootspartyworkaccountability4、拖动每一点到合适的位置（点住鼠标左键不放一直拖到合适的位置）：如图5、然后选择substract得到Secretarymusttreeprison"grasppartyisjob,notcaughtpartyisderelictionof,caughtbadpartyisnotcompetent"ofconsciousness,effectiveperformcaughtpartyfirstresponsibilitypeopleduties,seriouslyimpl
3、ementationgrass-rootspartyworkaccountability拿红外图谱举例：1、选择toolsàbaseline2、出现下面的窗口，选择baseline，将numberofpoints后的参数改小一些，比如2，点击Automatic，出现一条红色的基线。Secretarymusttreeprison"grasppartyisjob,notcaughtpartyisderelictionof,caughtbadpartyisnotcompetent"ofconsciousness,effectiveperformcaughtpartyfirstresponsibi

5、eduties,seriouslyimplementationgrass-rootspartyworkaccountability5、然后选择substract得到：6、关闭Baseline窗口，然后把鼠标对准基线右击，选择HideDatePlot，隐藏基线。谱图颜色双击后也可以修改。Secretarymusttreeprison"grasppartyisjob,notcaughtpartyisderelictionof,caughtbadpartyisnotcompetent"ofconsciousness,effectiveperformcaughtpartyfirstresponsi
6、bilitypeopleduties,seriouslyimplementationgrass-rootspartyworkaccountability7、得到修改过后的谱图。然后再调整X轴区间等，做进一步的调整。Secretarymusttreeprison"grasppartyisjob,notcaughtpartyisderelictionof,caughtbadpartyisnotcompetent"ofconsciousness,effectiveperformcaughtpartyfirstresponsibilitypeopleduties,seriouslyimplemen
