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

2 次查看(过去 30 天)
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

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?

  • 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

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