I want to plot these on a map with different markers and sizes for 
different values ranging from 0 to 47.
I followed few examples from ncl website. I need to get a plot like this 
https://www.ncl.ucar.edu/Applications/Images/polyg_8_lbar_lg.png

I am attaching the script and plot that I got. I am not able to 
understand what am I doing incorrectly. Please help me solve this.

Looking forward to any kind of help.

Thank you
Anie
