MATLAB: Line markers disappeared after save as .eps/.emf when yyaxis was used

plotyyyyaxis

Dear all,
I am currenty having the issues about disappeared line markers in the exported figures. The simplified example code is showing below:
clc, clear all
x = 1:10;
y1= 1*x;
y2= 0*x;
figure
newcolors = [1 0 0; 0 0 1];
colororder(newcolors);
[hAx,hLine1,hLine2] = plotyy(x,y2, x,y1); hold on
hLine1.LineStyle = '-';
hLine1.Marker = 'o';
hLine2.LineStyle = '--';
hLine2.Marker = 's';
ax = gca;
ax.YLim = ([0 1]);
figure
newcolors = [1 0 0; 0 0 1];
colororder(newcolors);
yyaxis left
plot(x,y2, ' o-'); hold on
ylim([0 1])
yyaxis right
plot(x,y1, ' s--'); hold on
For both methods, the pop-up figures have no issues. However, after saving the figures as .eps/.emf, the line markers disappears if yyaxis was used, while there is no issue if plotyy was used.
I could use plotyy for the figure plotting. However, I am wondering if someone help me with using yyaxis for the figure plotting? Many thanks.

Hi,
Can you elaborate on how you are trying to save your figure as '.eps' file, and the application you are using to view the eps file.
At my end, I am proceeding as follows:
clc, clear all
x = 1:10;
y1= 1*x;
y2= 0*x;
figure
newcolors = [1 0 0; 0 0 1];
colororder(newcolors);
[hAx,hLine1,hLine2] = plotyy(x,y2, x,y1); hold on
hLine1.LineStyle = '-';
hLine1.Marker = 'o';
hLine2.LineStyle = '--';
hLine2.Marker = 's';
ax = gca;
ax.YLim = ([0 1]);
print('fig1','-depsc2');
figure
newcolors = [1 0 0; 0 0 1];
colororder(newcolors);
yyaxis left
plot(x,y2, ' o-'); hold on
ylim([0 1])
yyaxis right
plot(x,y1, ' s--'); hold on
print('fig2','-depsc2');
