Hi,
I am plotting the 4 graphs in subplotting using the code below. but I want to use less amount of lines. Code is below!
Code:
files = ['F:\3-PIV_Experimental_Data\Outlet_110\Data_LaserSheet_D\Data_Head\Data_Raw\LaserSheet.xlsx'];
a = readtable(files);
x = a{:,16};
y = a{:,15};
files = ['F:\3-PIV_Experimental_Data\Outlet_110\Data_LaserSheet_C\Data_Head\Data_Raw\LaserSheet.xlsx']
a = readtable(files);
x1 = a{:,16};
y1 = a{:,15};
files = ['F:\3-PIV_Experimental_Data\Outlet_110\Data_LaserSheet_B\Data_Head\Data_Raw\LaserSheet.xlsx'];
a = readtable(files);
x2 = a{:,16};
y2 = a{:,15};
files = ['F:\3-PIV_Experimental_Data\Outlet_110\Data_LaserSheet_A\Data_Head\Data_Raw\LaserSheet.xlsx'];
a = readtable(files);
x3 = a{:,16};
y3 = a{:,15};
figure()
subplot(2,2,1)
plot(x,y,'*')
%Spacing and griding
xlim([0 6])
ylim([0 600])
hold on
grid on
% Design Head
y = 500;
line ([0,500],[y,y],'color','k','LineWidth',1);
txt = {'Design Head = 500 mm'};
text(1,560,txt)
x = 5;
line ([x,x],[0,500],'color','k','LineWidth',1);
%Chart Representation
title('DataLaserSheet-D');
xlabel('flowrate (l/s)');
ylabel('Head (mm))');
hold on
subplot(2,2,2)
plot(x1,y1,'*')
%Spacing and griding
xlim([0 6])
ylim([0 600])
hold on
grid on
% Design Head
y = 500; %17 mm
line ([0,500],[y,y],'color','k','LineWidth',1);
txt = {'Design Head = 500 mm'};
text(1,560,txt)
x = 5;
line ([x,x],[0,500],'color','k','LineWidth',1);
%Chart Representation
title('DataLaserSheet-C');
xlabel('flowrate (l/s)');
ylabel('Head (mm))');
hold on
subplot(2,2,3)
plot(x2,y2,'*')
hold on
%Spacing and griding
xlim([0 6])
ylim([0 600])
hold on
grid on
% Design Head
y = 500; %17 mm
line ([0,500],[y,y],'color','k','LineWidth',1);
txt = {'Design Head = 500 mm'};
text(1,560,txt)
x = 5;
line ([x,x],[0,500],'color','k','LineWidth',1);
%Chart Representation
title('DataLaserSheet-B');
xlabel('flowrate (l/s)');
ylabel('Head (mm))');
subplot(2,2,4)
plot(x3,y3,'*')
hold on
%Spacing and griding
xlim([0 6])
ylim([0 600])
hold on
grid on
%Design,Kickback and Flushflow ppoints
% Design Head
y = 500; %17 mm
line ([0,500],[y,y],'color','k','LineWidth',1);
txt = {'Design Head = 500 mm'};
text(1,560,txt)
x = 5;
line ([x,x],[0,500],'color','k','LineWidth',1);
%Chart Representation
title('DataLaserSheet-A');
xlabel('flowrate (l/s)');
ylabel('Head (mm))');
%over all chart title
sgtitle('Outlet-110 mm')

HI muhammed
all you need to do is put the subplots into a for loop and change the things that vary with subplot. That is the data of course, and also the sheet letter, A through D. Putting the x and y data into matrices allows them to be addressed by means of the for loop variable j:
% after obtaining the data, concatenate it into matrices
xm = [x x1 x2 x3];
ym = [y y1 y2 y3];
sheetlabel = 'DCBA'
figure(1)
for j = 1:4
subplot(2,2,j)
plot(xm(:,j),ym(:,j),'*')
%Spacing and griding
xlim([0 6])
ylim([0 600])
hold on
grid on
% Design Head
yy = 500;
line ([0,500],[yy,yy],'color','k','LineWidth',1);
txt = {'Design Head = 500 mm'};
text(1,560,txt)
xx = 5;
line ([xx,xx],[0,500],'color','k','LineWidth',1);
%Chart Representation
title(['DataLaserSheet-',sheetlabel(j)]);
xlabel('flowrate (l/s)');
ylabel('Head (mm))');
hold off
end

Try using the nexttile() function
nexttile;
instead of the subplot() function
subplot(2, 3, j)
