Hi I have 2 arrays
time_duration=[2 4 3 6 7 3 7]
Altitude=[20 30 40 50 60 60 50]
Sometimes, for the same time duration, I have 2 Altitude values. For example for time_duration= 3, I have Altitude = 40 ad 60. I want to plot it so that on the xaxis time_duration=3, I can have altitude 100 ie (40+60) on the yaxis.
I tried with barchart but it is not allowing it as of duplicate values.
bar(time_duration,Altitude)
XData cannot contain duplicate values.
Any suggestions?

[a1,~,c1] = unique(time_duration);
A1 = accumarray(c1(:),Altitude(:));
bar(a1(:),A1(:));

time_duration=[2 4 3 6 7 3 7]
Altitude=[20 30 40 50 60 60 50]
[unique_time_duration,jj,kk]=unique(time_duration)
new_Altitude=accumarray(kk,Altitude)
out=[unique_time_duration' new_Altitude]
