The problem is I have 5 values in my excel. I have to use them to plot those information in 2-D.5 values are month, day hour, demand and price. Here is the code I have

[v,T,vT]=xlsread('vermont_demand_price_2007.csv') 
% 'xlsx' for exell 2007
%v: Double
%T and vT : cell
%use v containing numbers 
t=v(:,3);y=v(:,5)
%if u have to plot second colone depending on first:
plot(t,y);
cubic_function=spline(t,y);
input = .1:.01:10;
plot(t,y)
hold on 
plot(input,ppval(cubic_function,input),'r')

but it does not like what I want it to be.

Hi,

Please elaborate on the error message you observe or share the snapshot of the error message. Also, if possible share the file ' vermont_demand_price_2007.csv' as this would help in debugging.
