Hello,
I'm generating heatmaps and histograms as EPS files for a Latex document. The heatmaps appear cleanly as expected, but the histograms are distorted. Attached is an example from when I opened them in Inkscape (the histograms still look blurry in the Latex PDF too while the heatmaps look fine).
Blurry histogram
Clear heatmap
Code:
figure(2)
histogram(myData,10)
grid on
xlabel('Max Insertion Loss (dB)'); ylabel('Occurences');
set(gca, 'FontSize',20);
set(gca,'XTick',IL_lim_min+5:10:IL_lim_max);
xlim([IL_lim_min, IL_lim_max])
ylim([occur_lim_min, occur_lim_max])
saveas(gcf,[pwd '\LCOM Figs\InsertionLossHistogram_LCOM_L3'],'epsc')
Any help would be great! Thanks.

Hi, I think the problem is in the transparency of the histograms, which is not supported either by save or export_fig functions. Transparency can be disabled with histogram(myData,10,'FaceAlpha',1)

I had same problem, and this worked. But what if transparency is needed?
I get same problem on a figure with plot and stairs, i guess since i needed to use fill in that figure with 'FaceAlpha' below 1.

hi, you could try export_fig from file exchange.

Thanks for the suggestion Joh. I tried that, but still the EPS outputs are pixelated and blurry.

is the result from export_fig('file.eps', '-q101') also distorted by the artifacts? i just saw that you opened the files with inkscape... i also had these quality problems back in a day. it was caused by the inkscape import library which yielded only poor quality images. you can try an export as pdf, check the quality in your favorite pdf viewer and then also try to import the pdf in inkscape. maybe this yields better results, at least you would know the cause of the problem.
