I want to show raindrop size distribution in MATLAB using contour mapping. My datafile contains number of drops. I want to show variation of drop diamtere with time.How to do that in MATLAB with filled contour?

What data you have? Have a look on pcolor, contour.

can you suggest the programme for contour mapping using this data?

在 MATLAB Online 中打开

dia = importdata('Rdrop_dia.txt') ;
Rtime = importdata('Rtime.txt') ;
Rdrop_nos = importdata('Rdrop_nos.txt') ;
% contourf(Rtime,dia,Rdrop_nos) 
pcolor(Rtime,dia,Rdrop_nos) 
shading interp 
colorbar

Thank you for your reply, but the contour map is not looking like the map in the picture shared by me( white background in the map). Kindly suggest for the same.

It depends on how your data is. Is the attached plot is for the given data?

So that is the plot from the data. Also try contourf; I have commented that line.

yes sir. I've tried that and applied to different data, but facing same issue(blue background).

May be you need to discard certain values.
