Draw a time series graph in which you indicate both minimum and maximum temperatures over the years

Answer 1

Solution: Given data is as follows;

Years	2009	2013	2017	2010	2014	2018	2011	2015	2019	2012	2016	2020
Max Temp	19	16	20	10	18	17	18	20	23	15	17	12
Min Temp	18	4	7	-2	4	8	8	4	13	4	5	6

after sorting by year from 2009 till 2020 we will get,

Years	2009	2010	2011	2012	2013	2014	2015	2016	2017	2018	2019	2020
Max Temp	19	10	18	15	16	18	20	17	20	17	23	12
Min Temp	18	-2	8	4	4	4	4	5	7	8	13	6

And hence the required plot is given by,

Best Luck !!
