Hey guys! I have one .csv file containing 8 columns. I want to plot 8th column (Time200) on x axis and remaining 7 columns on y axis. I did that but plots look messy, I mean its hard to interprate the difference among graphs. Is there any way to make these plots clear or interpratable. I will appreciate any kind of help. Thank you.

How about this:
% Initialization Steps.
clc; % Clear the command window.
close all; % Close all figures (except those of imtool.)
clear; % Erase all existing variables. Or clearvars if you want.
workspace; % Make sure the workspace panel is showing.
format long g;
format compact;
fontSize = 18;
data = importdata('Plotdata.csv');
timeData = data.data;
columnHeaders = data.colheaders;
[rows, columns] = size(timeData);
% Sort by column 8 in ascending order
timeData = sortrows(timeData, 8)
t = timeData(:, end); % Times are the last column.
% Make up colors for the plot lines
plotColors = jet(columns - 1);
% Plot columns 1 to columns-1
for col = 1 : columns - 1
y = timeData(:, col);
plot(t, y, '.-', 'Color', plotColors(col, :), 'LineWidth', 2, 'MarkerSize', 30);
hold on;
end
xlabel('Time', 'FontSize',fontSize);
ylabel('y', 'FontSize',fontSize);
grid on;
hold off;
legend(columnHeaders(1:end-1), 'Location', 'southwest')
[EDIT] plot with original data removed at poster's request.

As requested, I've changed my program to not use your data, which looked pretty generic by the way. I wrote a program to create some plots and run it with both unsorted times (like you have) and with the times sorted. The results are shown below:
% Demo by Image Analyst
% Initialization Steps.
clc; % Clear the command window.
close all; % Close all figures (except those of imtool.)
clear; % Erase all existing variables. Or clearvars if you want.
workspace; % Make sure the workspace panel is showing.
format long g;
format compact;
fontSize = 18;
% data = importdata('Plotdata.csv');
% timeData = data.data;
[t, timeData, columnHeaders] = CreateSampleData();
% columnHeaders = data.colheaders;
[rows, columns] = size(timeData);
promptMessage = sprintf('Do you want to sort the times?');
titleBarCaption = 'Sort?';
buttonText = questdlg(promptMessage, titleBarCaption, 'Yes', 'No', 'Quit', 'Yes');
if contains(buttonText, 'Quit', 'IgnoreCase', true)
return; % or break or continue.
elseif contains(buttonText, 'Yes', 'IgnoreCase', true)
% Sort time in ascending order
t = sort(t);
plotTitle = 'Using sorted times';
else
plotTitle = 'Using unsorted times';
end
% Make up colors for the plot lines
plotColors = jet(columns);
% Plot columns
for col = 1 : columns
y = timeData(:, col);
plot(t, y, '.-', 'Color', plotColors(col, :), 'LineWidth', 2, 'MarkerSize', 30);
hold on;
end
title(plotTitle, 'FontSize', fontSize);
xlabel('Time', 'FontSize',fontSize);
ylabel('y', 'FontSize',fontSize);
grid on;
hold off;
legend(columnHeaders(1:end), 'Location', 'southwest')
%=============================================================================================
function [t, timeData, columnHeaders] = CreateSampleData()
rows = 15;
columns = 8;
columnHeaders = cell(columns, 1);
baseCurve = linspace(0.17, 0.10, rows)';
t = 1 : rows;
% Scramble order of the times, like the original poster had.
randomOrder = randperm(length(t));
t = t(randomOrder);
% Add noise and lift
for col = 1 : columns
thisCol = baseCurve + .1 * col + 0.05 * rand(rows, 1);
timeData(:, col) = thisCol;
columnHeaders{col} = sprintf('Time %d', col);
end
end
