Why the resolution of the plot is bad when I plot longer data?
显示 更早的评论
The m-file 'procKM_tide.m' reads data file 'KM_tde.xlsx' and plot tidal data. I can't understand why the output figure shown on screen and png file present bad resolution. If I plot shorter duration of data, say 2022/12/1 ~ 2023/2/10, the resolution is OK! Why? Any solution?

Hello
your line is probably too thick
so change this parameter in this line
plot(tj2,zl,'b-','linewidth',1);%,'markersize',0.5);
I think linewidth value 0.5 to 1 is the optimal range
no need to increase the 300 DPI resolution , it's enough for what we do here

IMHO the resolution seems good , but if you want a better picture you can try with a higher DPI
have you tried for example with 600 or 1000 DPI ?
