Scatter plot text behind plotted data when image copied.

I have a figure containing a scatter plot overlaid with a fitted poly. I have added some text labels to the data.

When I copy the image and paste as enhanced metafile, the text appears behind the plotted data, even when I set the text object to 'top' and/or set the current axes to 'top':

t = text(x, y, str); % Adding a text label
uistack(t, 'top'); % Bring the text to the front
set(gca, 'Layer', 'top');

If I change the renderer to 'opengl', the image copies correctly, but the pasted image quality is very poor.

This behaviour is repeatable on any figure of this type.

Hey @Kirstie Beugger, can you attach the code as well as the data file (if any) for better understanding of the issue.

Hi Animesh,

Thanks for considering my issue.

This is the original code used to add the text to the plot:

function [t] = addText(x,y,xtxt,ytxt,n)
figure(n)
hold on
legend('AutoUpdate','off')
plot(x,y,"ko")
str = {strcat(xtxt,'%'),ytxt};
t = text(x,y,str);
hold off
end

This is the (simplified) code used to create the figure in the first place:

figure(i)
clf
hold on
%plot the raw data scatter plots
s1 = scatter(data_x,data_y);
s1.MarkerEdgeColor = '#E1E1E1';

%Create a fit object for the data and plot it
[fitresult, ~] = createFit_poly2(data_x,data_y);
plot(fitresult_SandFx(0:max(data_y)), 'k')

%set the correct display for the y axis values
ax = ancestor(s3,'axes');
ax.YAxis.Exponent = 3;
ytickformat('%.0f')

title('Plot Title');
ylabel('y axis label');
xlabel('x axis label');
grid('on');
hold off

saveas(figure(i),strcat('figure ', string(i)))

Thanks for the info @Kirstie Beugger. Looks like a bug.

When copying graphics in vector format the figure's renderer is switched to painters which causes the change in text position.

A workaround is to set the z coordinate of the text to a value greater than 0.

tobj = findobj(gca,'type','text'); 
for i = 1:numel(tobj)
    tobj(i).Position(3) = 1; 
end

Oh great, thanks Adam. I'm glad it's a bug, I've been wrestling with it for a while.

[Kirstie Beugger]

Mint, thanks a lot Adam!

For anyone else who needs to use this, Chat changed the code slightly:

tobj = findobj(gca, 'type', 'text');

for i = 1:numel(tobj)

tobj(i).Position(3) = 1;

end

Thanks for correcting that, Kirstie. Forgot the numel(). I fixed my answer.
