How to constrain the plot within the limits?

Hi everyone,

I am facing an issue while saving the figure in higher resolution. Figure get out of range plus axis labels also getting bigger.

May someone help me how can i fix this.

Here is my code:

D=figure (4)
D.Position(3:4)=[550,400];

subplot(311); 
yyaxis left 
plot(t,sf2(:, 2),'-b'); 
ylabel('Vent Fluid (\circC)')
%title('Vent Fluid Temp'); 
%grid on
yyaxis right
plot(t,sf1(:,2),'r-'); 
ylabel('Tidal amplitude (m)')
%legend('Vent','Tidal');
%         title('Tidal Height'); 
grid on
text(4.8,2257.5,'(a)')
%xlabel('Time (days)')
%legend('Tidal','Vent');




subplot(312); 
yyaxis left
yy1 = smooth(t,xxx,0.1,'loess');

yy2 = smooth(t,yyy,0.1,'loess');

plot(t,yy1,'-r', 'LineWidth',1)
ylabel('Normalized (\circC)')
yyaxis right
plot(t,yy2,'-b', 'LineWidth',1);
ylabel('Normalized (m)')
xlim([0.5 4.5]);
text(4.3,0.8,'(b)')
%xlabel('Time (days)'); 
%legend('Vent','Tidal'); 
grid on
subplot(313); 
%set(gcf,'position',[x_f,y_f,width,height])
yyaxis left
plot(t,xxx,'-r', 'LineWidth',1);
ylabel('Normalized (\circC)')
yyaxis right
grid on
plot(t,y3,'-b', 'LineWidth',1);
ylabel('Normalized (m)')
xlim([0.5 4.5]);
xlabel('Time (days)'); 
text(4.3,0.8,'(c)')
exportgraphics(D,'barchart.png','Resolution',300)

Here is what i get

and here is what i am looking for

Is this helpflul to you?

t =linspace(0, 5);

subplot(311); 
y1 = sin(2*pi*t);
y2 = sin(2*pi*t)+0.2*randn(size(t));
myplot(t, y1, y2,[0.5, 4.5], [-1.5, 1.5]);

subplot(312);
y1 = sin(3*pi*t);
y2 = sin(3*pi*t)+0.2*randn(size(t));
myplot(t, y1, y2,[0.5, 4.5], [-1.5, 1.5]);

subplot(313)
y1 = sin(3*pi*t);
y2 = sin(3*pi*t)+0.2*randn(size(t));
myplot(t, y1, y2,[0.5, 4.5], [-1.5, 1.5]);

function myplot(t, y1, y2, x_lim, y_lim)
    yyaxis left 
    plot(t,y1,'-b'); 
    xlim([x_lim(1), x_lim(2)]); ylim([y_lim(1), y_lim(2)]);
    set(gca,'fontsize',8) % set up font size
    ylabel('Vent Fluid (\circC)')
    %title('Vent Fluid Temp'); 
    grid on
    yyaxis right
    plot(t,y2,'r-'); 
    xlim([x_lim(1), x_lim(2)]); ylim([y_lim(1), y_lim(2)]);
    ylabel('Tidal amplitude (m)')
end

subplot(311); 
y1 = sf2(:, 2);
y2 = sf1(:, 2);
myplot(t,y1, y2,[0, 5], [-1, 1]);
grid on
subplot(312);
y1 = xxx
y2 = yyy
myplot(t, y1, y2,[0.5, 4.5], [-1, 1]);
subplot(313)
y1 = xxx;
y2 = y3;
exportgraphics(gcf,'aaa.png','Resolution',300)
myplot(t, y1, y2,[0.5, 4.5], [-1, 1]);


function myplot(t, y1, y2, x_lim, y_lim)
    yyaxis left 
    plot(t,y1,'-b'); 
    xlim([x_lim(1), x_lim(2)]); ylim([y_lim(1), y_lim(2)]);
    ylabel('Vent Fluid (\circC)', 'FontSize',8)
    %title('Vent Fluid Temp'); 
    grid on
    yyaxis right
    plot(t,y2,'r-'); 
    xlim([x_lim(1), x_lim(2)]); ylim([y_lim(1), y_lim(2)]);
    ylabel('Tidal (m)', 'FontSize',8)
    xlabel('Time (days)', 'FontSize',8)
end

Just to be sure, please execute the following lines before actually executing the code in the script:

clear % clear workspace
clc % clear command windows
close all % close all open figures

Answer 2

[Askic V]

The complete script with modifed myplot function is the following:

clear
clc
close all
t =linspace(0, 5);
subplot(311); 
y1 = sin(2*pi*t);
y2 = sin(2*pi*t)+0.2*randn(size(t));
% set up desired limits for x and y
myplot(t, y1, y2,[0.5, 4.5], [-1.5, 1.5],...
    'subplot1',{'Vent Fluid (\circC)','Tidal amplitude (m)'},7);

subplot(312);
y1 = sin(3*pi*t);
y2 = sin(3*pi*t)+0.2*randn(size(t));
% set up desired limits for x and y
myplot(t, y1, y2,[0.5, 4.5], [-1.5, 1.5],...
    'subplot2',{'Vent Fluid (\circC)','Tidal amplitude (m)'},7);

subplot(313)
y1 = sin(4*pi*t);
y2 = sin(4*pi*t)+0.2*randn(size(t));
% set up desired limits for x and y
myplot(t, y1, y2,[0.5, 4.5], [-1.5, 1.5],...
    'subplot3',{'Vent Fluid (\circC)','Tidal amplitude (m)'},7);

exportgraphics(gcf,'aaa.png','Resolution',300)

function myplot(t, y1, y2, x_lim, y_lim, x_label, y_label, font_size)
    yyaxis left 
    plot(t,y1,'-b'); 
    xlim([x_lim(1), x_lim(2)]); ylim([y_lim(1), y_lim(2)]);
    set(gca,'fontsize',font_size) % set up font size
    ylabel(y_label{1})
    grid on
    yyaxis right
    plot(t,y2,'r-'); 
    xlim([x_lim(1), x_lim(2)]); ylim([y_lim(1), y_lim(2)]);
    ylabel(y_label{2})
    xlabel(x_label);
end

This script will produce aaa.png file that is attached.

@Askic V Xlabel is common, so its better to appear only for last panel. Plus the y-axis for top panel are not within the range of -1, 1 rather the primary y-axis have different scale and secondry y-axis have different scale.

[Andi]

@Askic V I dont know why but again i get same output in the saved file. May be something wrong while using the online matlab

[Askic V]

This is really strange, because, the script I posted is executed online by clicking on the green play button. So the latest version of the Matlab (2022b) is executing the code. You do get correct figure, but only saved .png file is not correct?

[Askic V]

Regarding your question about different limits for left and right axis, please have a look at the following variant:

%%
clear
clc
close all
t =linspace(0, 5);
ax1 = subplot(311); 
y1 = sin(2*pi*t);
y2 = sin(2*pi*t)+0.2*randn(size(t));

myplot(t, y1, y2,...
    'subplot1',{'Vent Fluid (\circC)','Tidal amplitude (m)'},7);
% set up desired limits for x and y
xlim([0.5, 4.5]);
y_lim_left = [-1.5, 1.5];
y_lim_right = [-2, 2];
ax1.YAxis(1).Limits = y_lim_left;
ax1.YAxis(2).Limits  = y_lim_right;

ax2 = subplot(312);
y1 = sin(3*pi*t);
y2 = sin(3*pi*t)+0.2*randn(size(t));

myplot(t, y1, y2,...
    'subplot2',{'Vent Fluid (\circC)','Tidal amplitude (m)'},7);
% set up desired limits for x and y
xlim([0.5, 4.5]);
y_lim_left = [-1.5, 1.5];
y_lim_right = [-2, 2];
ax2.YAxis(1).Limits = y_lim_left;
ax2.YAxis(2).Limits  = y_lim_right;

ax3 = subplot(313)

ax3 = 
  Axes with properties:

             XLim: [0 1]
             YLim: [0 1]
           XScale: 'linear'
           YScale: 'linear'
    GridLineStyle: '-'
         Position: [0.1300 0.1100 0.7750 0.2157]
            Units: 'normalized'

  Show all properties

y1 = sin(4*pi*t);
y2 = sin(4*pi*t)+0.2*randn(size(t));

myplot(t, y1, y2,...
    'subplot3',{'Vent Fluid (\circC)','Tidal amplitude (m)'},7);
% set up desired limits for x and y
xlim([0.5, 4.5]);
y_lim_left = [-1.5, 1.5];
y_lim_right = [-2, 2];
ax3.YAxis(1).Limits = y_lim_left;
ax3.YAxis(2).Limits  = y_lim_right;

exportgraphics(gcf,'aaa.png','Resolution',300)

function myplot(t, y1, y2, x_label, y_label, font_size)
    yyaxis left 
    plot(t,y1,'-b'); 
 
    set(gca,'fontsize',font_size) % set up font size
    ylabel(y_label{1})
    grid on
    yyaxis right
    plot(t,y2,'r-'); 
    ylabel(y_label{2})
    xlabel(x_label);
end
