I am plotting a circle marker [plot(...'o'...)] and then overprinting whiskers [plot(...'-'...)] in the horizontal and vertical directions.

When I print with the Painters renderer, the marker is shifted. So the crosshairs of the whiskers are no longer centered (see painters.png).

filename=['test79']; print(gcf, '-painters', '-dpdf', [filename,'.pdf']);

When I print with the opengl renderer, the image is degraded(undesired) and blurry, but the crosshairs are centered (desired) (see opengl.png).

Is there a way to obtain both a high quality pdf with proper marker orientation? Any help would be greatly appreciated.

Thank you.

Hi, can you share your version of MATLAB and code snippet to reproduce this issue?

Dear Mukul Rao, Thank you for looking into this issue. I am using R2017a. I am sharing a sample code (debugme.m) that leads to the same behavior. The 1:1 line is plotted and passes through the intersection of the crosses, but not the center of the circular markers. The markers are consistently shifted up and to the left (see test01.pdf).

Thank you for any insight you can provide.
