Different output figure by export_fig and save function in gui
显示 更早的评论
Hi there, I used aDot.MarkerHandle.FaceColorData = uint8(255*[LineColor(g,:) 0.5]') to change the alpha value of the plot. The figure should looks like this
but if I use export_fig, print or saveas function, the output color becomes like this
though by press the save button in file menu the transparent color is correct, the resolution is poor. Can some one help me to solve this problem??
Thanks, Heather.

export_fig, print and saveas only support foreground transparency in export to PNG files, and then only for patches. Read export_fig's documentation for details.
Even so, the techniques I mentioned in UndocumentedMatlab for achieving on-screen marker and line transparency do not work when exporting, to any format, because the plot gets reset by the print command (which is used by export_fig) in preparation for printing.
Instead of the above, I suggest that you use the ScreenCapture utility, which does not rely on the print function.

Do you create an EPS file? Then the answer is easy: EPS does not support transparency.
