Plot multiple arrays within a cell on a single figure

Hi folks,
I'm looking for a simplified method for plotting several matrices nested within a cell onto a single figure. Currently I'm using a for loop to cycle through the indices and plot each matrices individually:
figure(1)
for i=1:8
VP(i) = plot(cell{i}(:,1),cell{i}(:,2),'Marker','none',...
'LineWidth',3,'Color',C{i},'DisplayName',[scenario,'-',num2str(i)]);
hold on
end
The cell (cell) contains eight matrices. Here I'm plotting the second column of each matrix as a function of elements in their respective first column. I'd also like to have the colours be different -- hence the cell C{i} which takes a cell of prescribed colours and applies it to data set i in the loop. Variable VP allows me to easily generate a legend to delineate the different plots. Please let me know if there's a way to remove the need for a for loop. I was thinking about just replacing i with 1:8, but it doesn;t operate in the same manor as plotting a subset of a matrix:
VP(1:8) = plot(Array_cell{1:8}(:,1),Array_cell{1:8}(:,2),'Marker','none','LineWidth',3,'Color',C{1:8},'DisplayName',[scenario,'-',num2str(1:8)]);
Please let me know what you can come up with. I'd really appreciate the insight.

If you're just looking to clean up your code you can replace the loop with a cellfun(), but the time will be similar because it's functionally the same as a for loop.
hold on
cellfun(@(x) plot(x(:,1),x(:,2)),Array_cell(1:8));
I'm not sure about line color off the top of my head, but you can probably set that property directly afterwards.

You could use the plot syntax that accepts multiple X & Y pairs. Using a comma-separated list would make that simpler to work with.
