Variable name in title
显示 更早的评论
After loading in a data file, the following variables are assigned to the individual columns of the data file:
pressure1=dataFile(:,1);
temperature1=dataFile(:,2);
humidity1=dataFile(:,3);
...
If I plot all the columns using a for loop,
for i=1:47
figure;
Plot(dataFile(:,i))
title
saveas
close
end
then what to write in the title line so that it automatically puts 'pressure1' as the title when i=1, 'temperature1' as the title when i=2, 'humidity1' as the title when i=3, and so on? Also, how to use the saveas command (or any other alternative) so that the figure gets saved in the variable names, i.e. pressure1.jpg, temperature1.jpg, humidity1.jpg etc.

Do not put meta-data into variable names. This is a bad practice that makes code complicated and buggy:
Learn from the experts: use indexing, and do not numbers in your variable names.

Althoug meaningful names of variables are a good programming practice, they should not carry information which is used for processing. The output of a program should be the same, if a variable is renamed. Then:
NameList = {'pressure1', 'temperature1', 'humidity1', ...}
for i=1:47
figure;
plot(dataFile(:, i))
title(NameList{i})
end

how do i use loops to find the min and max value within a specified range of values.
every 0.5 seconds there is a sample taken. 0 to 0.5s one max and min value ...so 0.5s= 1 cycle. totally 10000 cycles.
please see the attached text file with this comment

This does not appear to be related to the original question. Ask it as a new question instead of as a comment on an answer for this existing question.

for i=1:47
figure;
Plot(dataFile(:,i))
str = strcat('pressure',num2str(i)) ;
title(str)
saveas(gcf,str,'jpg')
close
end
