Hist3 issue , white lines appear in the plot

Hi all,

so im using hist3 to plot my data ,

i have two vectors, M and N, and edges for each of them;

edges_M=linspace(min(M), max(M),bins-1);

edges_N=linspace(min(N),max(N),bins-1);

edges={edges_M,edges_N};

[kxx, c]= hist3([M, N],'Edges',edges);

Normalization=kxx./max(kxx); (i do normalization per col, (per N vec))

pcolor(c{2},c{1},Normalization)

BUT

i get:

So what those lines? (white) Why does they appear in my plot? what they represent/ or not? how to deal with them?

I suspect it is a bug in hist3, but i really like matlab so better solve it and not run to other program XD,

Best,

Can you share the entire code including the vectors and the edges?

hi actually my vectors are really long (24,950,000X1) so not sure how.

anyway i suspect more that it is a bug since in some runs it does not appear anywhere...(and in the last runs i did it work fine now :-) )

now im trying to do somthing else. which i would like help in,

so im using pcolor to plot my data as follow (i have vec_x, vec_y)

figure(3)

bins=50;

edges_x=linspace(min(vec_x), max(vec_x),bins-1);

edges_y=linspace(min(vec_y),max(vec_y),bins-1);

edges={edges_x,edges_y};

[kxx, c]= hist3([vec_x, vec_y],'Edges',edges);

Normalization=kxx./max(kxx);

pcolor(c{2},c{1},Normalization)

actually i want to change edges_y to be

edges_y=linspace(-0.6,0,bins-1);

but since my data in this vec is different range i get somthing like this:

how can i fix the figure such that where there is no data - it will be blue (which represent 0 prob)?

Best,

Lital
