assign differernt marker and put an offset in x-axis in subplot()

I have an array y(15 rows, 80 columns) and x(1,80) and want to plot each row of y against x.

I wonder how I can assign differernt marker to each plot. there are 15 rows in array y so I need 15 different markers.

I also wonder how I can put an offset in x-axis since the markers for the first x and y falls on y axis.

I would be grateful for your help.

x=1:80;

y=rand(15,80);

j=1;

for i=1:16

   subplot(6,3,i),plot(x(j:j+4),y(:,j:j+4),'LineStyle','none','Marker'
,'+')

 j=j+5;

end

You have 15 different patterns, and since there are only 13 possible markers, why not divide them up using (5 markers) x (3 colors)?

x=1:80;

y=rand(15,80);

j=1;

%5 different markers, 3 different colors
markerlist = {'+' 'x' 'o' 's' 'd'};
colorlist = {'r' 'k' [.5 .5 1]};

for i=1:16
    subplot(6,3,i)
    hold on;
    row = 0;
    for kk = 1:3
        for jj = 1:5
            row = row+1; 
            plot(x(j:j+4),y(row,j:j+4),'LineStyle','none','Marker',...
                markerlist{jj},'color',colorlist{kk})
        end
    end
    j=j+5;

      %Add offset
      xlim(xlim + [-0.5 0.5]);
  end

thanks a lot Teja for the help.

about the offset in x-axis, for the even subplots it is fine for the odd subplots there's an extra x label. Is it possible to remove those extra x labels?

Two comments

• You can easily plot a group of lines using a single call to the plot function if you arrange each column of the y matrix to be a separate line plot's data (so, make it 80-by-15 instead of 15-by-80)
• You can get a list of all available markers (there are 13 of them) from the set function

Here's an example

x = (1:80)';
y = rand(80,15);
plotHandles = plot(x,y,'Linestyle','none');
markerNames = set(plotHandles(1),'Marker');
for i = 1:length(plotHandles)
    markerIndex = mod(i,13)+1
    set(plotHandles(i),'Marker',markerNames{markerIndex});
end

Jarrod, in this case he's doing 5 points at a time, on 16 different subplots, so I don't think he can just plot it all at once.

[Teja Muppirala]

But this was very clever:

markerNames = set(plotHandles(1),'Marker');

It had never occurred to me that you could do that.

oops, i read it quickly. good point Teja :)

thanks Jarrod for the help. I learnt some good points from your code.
