评论： University 2024-2-9

I have a two different plots with 2 different axes. The second plot (fig2) is extracted from the first plot (fig1).

Please how can I make the extract plot to have the same axis as the first one. I tried aspect ratio function but couldn't work.

openfig('fig1.fig');

openfig('fig2.fig');

See code:

fig2 = figure(2);
[C,h] = contourf(L, xi, intul, [min(min(intul)):0.05e-11:max(max(intul))],'ShowText','off','edgecolor','none');
c = colorbar;
c.TickLabelInterpreter='latex';
c.Label.String = '$\int u_L \mathrm{dz} $';
c.Label.Interpreter = 'latex';
colormap jet
clabel(C,h)
hold on
for i=1:length(L)
    for j=1:length(xi)
        plot(L(i), xi(j), 'w.', 'LineWidth', 2, 'MarkerSize', 5)
    end
end
set(gca,'clim',[min(min(intul)) max(max(intul))]);

fig2 = figure(2);
[C,h] = contourf(L, xi, intul, [min(min(intul)):0.05e-11:max(max(intul))],'ShowText','off','edgecolor','none');
c = colorbar;
c.TickLabelInterpreter='latex';
c.Label.String = '$\int u_L \mathrm{dz} $';
c.Label.Interpreter = 'latex';

for i=1:length(L)
    for j=1:length(xi)
        plot(L(i), xi(j), 'w.', 'LineWidth', 2, 'MarkerSize', 5)
    end
end
set(gca,'clim',[min(min(intul)) max(max(intul))]);
% axis label
xlabel('HAN region length, $l$ [m]','Interpreter','latex');
ylabel('activity, $\xi$','Interpreter','latex');
xlim([pars.W/1000, pars.W/3])
ylim([0, 125])

I set the limit of fig2 using the axix of fig1.
