Plot data for unique temperatures imported from text file
显示 更早的评论
Hello,
I would like to plot the reaction against concentration on a 3 by 1 subplot for each unique temperature in the imported text data file. I think I need to put it in a loop but I'm not sure how to get it to plot.
Any help is appreciated, the code I have so far is below and text file ('reactions.txt') is attached.

You're forgetting several things:
- You are plotting the entire c and r vectors, not just the parts that belong to a specific temperature.
- You use hold on before creating the first plot in the subplot axes.
- The a variable describes positions in your temp array, not its values.

%% code starts here
r_data = importdata('reactions.txt');
%reaction_data = r_data.data;
%fid=fopen('reactions.txt');
t = reaction_data(:,1); %temperatures in vector
c = reaction_data(:,2); % concentration
r = reaction_data(:,3); % reaction rate
temp = unique(t);
for a = 1:length(temp)
L= t==temp(a) ;
if temp(a)==323
subplot (3,1,1)
plot(c(L),r(L))
elseif temp(a)==333
subplot(3,1,2)
plot(c(L),r(L))
elseif temp(a)==343
subplot(3,1,3)
plot(c(L),r(L))
else
warning('temperature of %.0f not plotted',temp(a))
end
end
