Hi, I would like to plot a line graph that can show by year and month on the x-axis just like the picture below.
The date data type that I have is in this format.
Here is the x variables that I use to construct the line graph.
However, the output of the line graph only showing Year.
If I remove the date hierachy and left only Month
It shows all the month without seperate into Yeat.
My 2 questions are:
1. How to display the line graph by Month and Year.
2. I measure unable to use for line graph? Why?
