在 MATLAB Online 中打开

I was plotting a graph and saved it to jpg using saveas

I used xlim to limit the range of x axis, but there are some line remain on the graph to the right of the graph.

This didn't show up in the figure box of MATLAB

but shows in the jpg file I save

please help me, thank you!

Here's the code I use

subplot(2,2,4)
yyaxis left
h(1) = plot(t_vec,Chiller_RAC_Load_Tons*3.5168525,'LineWidth',1);
hold on
ylabel('Chiller Power [kW]')
xlabel('Time')
yyaxis right
h(2) = plot(t_vec,Ptotal,'LineWidth',1);%Plotting HVAC Power
xlabel('Time')
ylabel('Fan Power [kW]')
title(sprintf('Chiller Power and Fan Power %s/%s/%d',Month_str,Date_str,Year))
hold on;
xline(E1_start,'LineWidth',1,'Color','black')
xline(E1_end,'LineWidth',1,'Color','black')
xline(E2_start,'LineWidth',1,'Color','black')
xline(E2_end,'LineWidth',1,'Color','black')
%legend(h(1:2),'Chiller Power','Fan Power')
xlim([5 20]);
xticks([7 9 11 13 15 17 19 21 23])
xticklabels({'7:00','9:00','11:00','13:00','15:00','17:00','19:00','21:00','23:00'})
set(gca, 'FontSize', 10);
saveas(gcf,sprintf('Chiller Tonnage and Fan Power %s-%d-%d.jpg',Month_str,Date,Year))
