How do I plot filled markers on top of two axis

I got this minimal example:

X = linspace(1,10,20);

% Create left axis
ax1=gca;
p1 = plot(X, sin(X),'MarkerFaceColor','w','Marker','s','MarkerSize',10);

% Create right axis
ax2=axes('Position',get(ax1,'Position'),'YAxisLocation','right','Color','none');hold on
p2 = plot(X,cos(X), 'Color', 'r','MarkerFaceColor','w','Marker','o','MarkerSize',10);

and get this figure:

The rectangular marker on the right side is a white filled marker and should cover the axis line like the circular one. How can I do that?

Thx,

best regards

Stefan

Try changing the order:

X = linspace(1,10,20);

% Create axes
ax1=gca;
ax2=axes('Position',get(ax1,'Position'),'YAxisLocation','right','Color','none');hold on
p1 = plot(X, sin(X),'MarkerFaceColor','w','Marker','s','MarkerSize',10);
p2 = plot(X,cos(X), 'Color', 'r','MarkerFaceColor','w','Marker','o','MarkerSize',10);

Okay thanks, but I guess my example was not good enough for my problem. Your solution fails with this one:

X = linspace(0,500,6);
Y1 = [1132;1241;1310;1409;1433;1452];
Y2 = [0;237;312;410;523;628]

% Create axes
ax1=gca;
ylim([0, 1500])
p1 = plot(X, Y1,'MarkerFaceColor','w','Marker','s','MarkerSize',10);

ax2=axes('Position',get(ax1,'Position'),'YAxisLocation','right','Color','none');hold on
ylim([0, 700])
p2 = plot(X, Y2, 'Color', 'r','MarkerFaceColor','w','Marker','o','MarkerSize',10);

linkaxes([ax1 ax2],'x')

Any suggestions?

[Alan Stevens]

Try

X = linspace(0,500,6);
Y1 = [1132;1241;1310;1409;1433;1452];
Y2 = [0;237;312;410;523;628];

% Create axes
ax1=gca;
ax2=axes('Position',get(ax1,'Position'),'YAxisLocation','right','Color','none');hold on

ylim([0, 700])
p2 = plot( X, Y2, 'Color', 'r','MarkerFaceColor','w','Marker','o','MarkerSize',10);

ylim([0, 1500])
p1 = plot( X, Y1,'Color','b','MarkerFaceColor','w','Marker','s','MarkerSize',10);

linkaxes([ax1 ax2],'x')

[steefan85]

Doesn't work, because both plots are now in ax2.

At the latest when I try to scale ax1 and ax2 differently it doesn't work.

I'd like to have set(ax1, 'YLim',[1100 1500]) and set(ax2, 'YLim',[0 700]).

Thanks.

Third time lucky?!

X = linspace(0,500,6);
Y1 = [1132;1241;1310;1409;1433;1452];
Y2 = [0;237;312;410;523;628];

% Create axes
ax1=gca;
ax2=axes('Position',get(ax1,'Position'),'YAxisLocation','right','Color','none');hold on

ylim([0, 700])
p2 = plot(ax1, X, Y2, 'Color', 'r','MarkerFaceColor','w','Marker','o','MarkerSize',10);

ylim([0, 1500])
p1 = plot(ax2, X, Y1,'Color','b','MarkerFaceColor','w','Marker','s','MarkerSize',10);

linkaxes([ax1 ax2],'x')

[Alan Stevens]

Nope! Now the last white circle has a line through it!

[steefan85]

Even if I first create the axes and then plot into them seperately:

X = linspace(0,500,6 );
Y1 = [1132;1241;1310;1409;1433;1452 ];
Y2 = [0;237;312;410;523;628];

% Create axes
ax1=gca ;
ax2=axes('Position',get(ax1,'Position'),'YAxisLocation','right','Color','none');hold on

set(ax2, 'YLim',[0 700])
plot( X, Y2, 'Color', 'r','MarkerFaceColor','w','Marker','o','MarkerSize',10,'Parent', ax2);

set(ax1, 'YLim',[1100 1500])
plot( X, Y1,'Color','b','MarkerFaceColor','w','Marker','s','MarkerSize',10, 'Parent', ax1);

linkaxes([ax1 ax2],'x')

The line goes through the square again...

I also tried:

plotyy or yyaxis

I can not do it.

[Alan Stevens]

How about this with yyaxis

X = linspace(0,500,6);
Y1 = [1132;1241;1310;1409;1433;1452];
Y2 = [0;237;312;410;523;628];

p2 = plot(X, Y2, 'Color', 'r','MarkerFaceColor','w','Marker','o','MarkerSize',10);
ylim([0, 700])

yyaxis('right')
p1 = plot(X, Y1,'Color','b','MarkerFaceColor','w','Marker','s','MarkerSize',10);
ylim([0, 1500])

Ok, the color of the right hand axis is not black, but there's probably a simple fix for that!

[steefan85]

That was my very first try and it works at the screen. BUT I need a vector graphics, so afterwards I have to set

set(gcf, 'renderer', 'painters');

And then I get:

It cuts off my markers at the axis!

Then the pdf looks like:

[Alan Stevens]

Have you tried printing to pdf? I got the following by printing to pdf995:

I managed to turn the right side axis black by going to the Property Inspector and Looking under Ruler.

[steefan85]

I can't just plot it as pdf. I need a special font (LM Modern 10) for the axes. Eps and pdf don't do this out of Matlab, because the fonts are not embedded.

My way is to print as .svg and then export it to .pdf via Inkscape automatically.

Printing a non-vector graphic is not applicable.

[Alan Stevens]

Hmm. I guess the only other option is to export the data and plot it in another tool that does all you want. Apart from that, I'm out of ideas! This is a long way from your original question!
