hello!
so i have a table with 5 columns.
column 1 has values 1-12 (but this can vary depending on the data set), column 2 is time, column 3 is either 1 or 0 (right/left), and column 4 and 5 are x and y co-ordinates respectively.
i need to plot the values in column 4 and 5 based on the index value in column 1.
so if the index value is 88 for 1, i want to plot column 4 and 5 from 1 -88.
if the next index is 98 for 2 , i want to 4 and 5 from 88 - 186
etc
i would also like to set up subplots based on the unique numbers in column 1 (i.e 1-12)
i have no code. i have absolutely no idea how to implement this.
this only script i have is determining the index.

[C,ia,ib] = unique(column1) ; % column1 is your column
idx = zeros(size(column1)) ; % make indices to save each class
for i = 1:length(C)
idx(ib==i) = i ;
end
gscatter(x,y,idx) % use gscatter (x,y) are your values to be plotted

[C,ia,ib] = unique(column1) ; % column1 is your column
for i = 1:length(C)
figure(i)
plot(x(ib==i),y(ib==i)) ;
end

THANK YOU SO MUCH ! THATS EXACTLY WHAT I WANTED!!!
also,
is there a way to change the colour of the figures based on whether column 3 is a 0 or a 1?
for i = 1:length(C)
figure(i)
gscatter(x(ib==i),y(ib==i), g(ib==i));
title(sprintf('COP %d',i))
end
this is my script so far
