plotting as it is x- axis for first column and y axis for two part one y for second column and above that third column y value? (mean one y and then above that other value for clear visualization in plot)

First column represent x axis, second and third column represent y-axis, want to generate plot with x axis as the values are there and y axis for second column and above that plot the y axis for third column? how can it be?

If s is your matrix
x=s(:,1);
y1=s(:,2);
y2=s(:,3);
plotyy(x,y1,x,y2)

x=s(:,1);
y1=s(:,2);
y2=s(:,3);
plot(x,y1,'g')
hold on
plot(x,y2,'b')

This type of plotting of y values I want? How can I?

do you mean this? your question is not very clear.
figure; hold on;
a = subplot(2,1,1); plot(y1,x);
b = subplot(2,1,2); plot(y2,x);
linkaxes([a b],'x');
you cannot have two y axis in a single figure. you could have subplots, each with one x axis and one y axis. in each subplot you can plot as many curves as you want. you could do that like this:
figure; subplot(1,2,1);
hold on;
plot(y1,x, 'r');
plot(y2,x, 'b');
.
.
.
plot(y1000, x, 'k');
hold off;
subplot(2,1,2);
hold on;
plot(yy1,x, 'r');
plot(yy2,x, 'b');
.
.
.
plot(yy1000, x, 'k');
hold off;
you could use different colors (specified by 'r' & 'b', etc) for each plot. see and read more in:

yes it is but want to remove that upper plot x-axis and merge with the lower one? something like second one which I edited in paint? How can do this in MATLAB?

What you painted here is not possible, and doesn't even make sense mathematically! I mean, the Y-values increase, then decrease and increase again with a different rate?!! The closest thing to what you want is to not display the second X-axis labels. Take a look here: http://www.mathworks.com/matlabcentral/fileexchange/7169-samexaxis-nice-subplots-with-same-x-axis
