Overlaying two time charts with different ranges

[jenniferbarlow_]

Hi, 

I am trying to overlay two timecharts with different date ranges 

The code for the first time chart is for the date range March 1993- June 30th 2019 : 

index="midas_temp”     MET_DOMAIN_NAME=DLY3208 MET_DOMAIN_NAME=DLY3208   | eval trange=MAX_AIR_TEMP - MIN_AIR_TEMP | fields trange |bucket span=1d _time | stats avg(trange) AS avgdailytrange by _time |eval Month-Day=strftime(_time,"%m-%d")|chart avg(avgdailytrange) AS "average trange" by Month-Day

And the second time chart is for the date range March - June 2020: 

index="midas_temp" MET_DOMAIN_NAME=DLY3208 |eval trange=MAX_AIR_TEMP - MIN_AIR_TEMP|timechart avg(trange) span=1day

Is there a way I can put these two lines on the same timechart? 

Thanks
