MAKING A SCATTER PLOT BASED ON INDEX VALUES

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

hi thanks for your suggestion.

unforntunately it does not execute what i want from it.

column 1 refers to foot steps. it still plots all 6 foot steps.

i need it to plot the 6 individually in seperate subplots :)

[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
