Histogram Loop Color Issue

Help with keeping my two colors on each histogram.

Each of k-histograms below have two two different colors plotted, orange for neurons=<800 and blue>800. For some reason, on the second k-loop, the colors for both plots default to just blue. I've attached my data, 5x2036 double. Each row in attached matrix, produces each k-histogram in code below.

figure(103) % NEURON POPULTATION SPIKE COUNTS, DURING LAST 2000 ms

nBinsN=(800-1)+1; % number of neuron bins

for k=1:size(sendersSp,1)

subplot(1,size(sendersSp,1),k)

histogram(sendersSp(1,(sendersSp(k,:)<=800)),nBinsN,'FaceColor',[0.9290 0.6940 0.1250],'EdgeColor',[0.9290 0.6940 0.1250],'EdgeAlpha',0.3,'BinMethod','integers')

ylabel('spike count');

xlabel('neuron #');

title(['Pttrn ',num2str(k),' Spikes']);

hold on

histogram(sendersSp(1,(sendersSp(k,:)>800)),nBinsN,'FaceColor',[0 0.4470 0.7410],'EdgeColor',[0 0.4470 0.7410],'EdgeAlpha',0.3,'BinMethod','integers')

hold off

end

Appreciate any suggestions to maintain two colors on each k-histogram. Thank you.

just found my error:

histogram(sendersSp(1,(sendersSp(k,:)<=800))...

should be written as

histogram(sendersSp(k,(sendersSp(k,:)<=800))
