MATLAB: MAKING A SCATTER PLOT BASED ON INDEX VALUES

for loopgscatterhelpif loopindexMATLABplotscattersubplotssyntax

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
