help with time format & trend vs.seasonal plots

Hi,

I'm just starting out with Gnuplot ans would appreciate help with a plot. 

I'm plotting from a csv file with monthly output data for 7 years, for Jan 2014 through Dec 2020. Here's a sample of the file:

#1,2
#Date,F001
1/31/2014,1028
2/28/2014,909
3/31/2014,687
4/30/2014,832
5/31/2014,971
6/30/2014,790
7/31/2014,886
8/31/2014,997
9/30/2014,983
10/31/2014,945
11/30/2014,817
12/31/2014,1009
1/31/2015,973
2/28/2015,782
3/31/2015,35
4/30/2015,0
5/31/2015,129
6/30/2015,386
7/31/2015,626
8/31/2015,467
9/30/2015,360
10/31/2015,205
11/30/2015,164
12/31/2015,437
...
12/31/2020,383


I'm able to plot the trend (i.e. the full range from Jan 14 to Dec 2020).I would also like to create a seasonal plot that plots Jan-Dec for each year.
I can get one year to (almost) work using the following commands:

set datafile separator ","
set xdata time
set timefmt '%m/%d/%Y'
set title "Seasonal"
set ylabel "Units"
set xlabel "Date"
set yrange [0:1200]
set xrange ["1/1/2014":"12/31/2014"]
set format x "%m"
plot "Data_File.csv" u 1:2 w linesp notitle

What's the proper syntax to create a plot with one line for 2014 and another line for 2015? Also, the plot generated by the script plots the first data point, 1/31/2014, 1028 aligned over 02 (Feb) on the X axis.

Thanks in advance for the help!

David
