2、選中數據，使用“line+symbol”方式繪圖。
/iknow-pic.cdn.bcebos.com/ae51f3deb48f8c5433d62d4e35292df5e0fe7f4e"target="_blank"title=""class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/ae51f3deb48f8c5433d62d4e35292df5e0fe7f4e?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="/ae51f3deb48f8c5433d62d4e35292df5e0fe7f4e"/>
3、進行圖標symbol設置，設置為三角形。雙擊線就會出現plotdetail，或者選中線後右鍵plotdetails。
/iknow-pic.cdn.bcebos.com/ac6eddc451da81cbd4fc6bac5d66d016092431bd"target="_blank"title=""class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/ac6eddc451da81cbd4fc6bac5d66d016092431bd?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="/ac6eddc451da81cbd4fc6bac5d66d016092431bd"/>
4、進行圖例顯示設置，選中圖例/圖標，右鍵選擇打開properties設置，
/iknow-pic.cdn.bcebos.com/023b5bb5c9ea15ce5a7c0868b9003af33b87b2c5"target="_blank"title=""class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/023b5bb5c9ea15ce5a7c0868b9003af33b87b2c5?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="/023b5bb5c9ea15ce5a7c0868b9003af33b87b2c5"/>
5、然後在彈出來的窗口中，更改格式，註意格式為“\l(線編號)名稱”，如“\l(2)”，“\l(2.1)”。
/iknow-pic.cdn.bcebos.com/50da81cb39dbb6fdbd110d470624ab18972b370d"target="_blank"title=""class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/50da81cb39dbb6fdbd110d470624ab18972b370d?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="/50da81cb39dbb6fdbd110d470624ab18972b370d"/>
6、回車確定，這樣就完成了。
