Can you exclude dates in date range using xlim?
显示 更早的评论
I have a dataset where the x axis is time and the y axis is sound pressure level in dB. The data is recorded continuously on a 24hr cycle, but I'm not interested in the data collected at night. Is there a way to exclude this data using xticks or xlim?
At the moment I have:
xlim([start_dt, end_dt]); %filter to date range of interest
Would the best way to address this be to replace sd with multiple datetime ranges somehow to exclude the evening data? I'm not sure how to code this?

With xticks() and xticklabels(), you can show any values you'd need to display.

While plotting itself, you take the required data and plot.

dn = now + [0:.5:48]/24;
y = randn(size(dn));
subplot(311)
plot(dn, y)
datetick('x')
subplot(312)
idx = hour(dn)>7 & hour(dn)<20; % day
dn1=dn(idx);
y1=y(idx);
plot(dn1, y1)
datetick('x')
subplot(313)
idx = hour(dn)>7 & hour(dn)<20; % day
dn1=dn(idx);
y1=y(idx);
plot(1:length(y1), y1)
hold on
i1 = find(diff(dn1)>0.6/24);
xline(i1+1);
h=gca;
h.XTick=1:5:length(y1);
h.XTickLabel = datestr(dn1(1:5:end), 'HH:MM:SS');
h.XTickLabelRotation = 30;

What is your matlab ver? A work around is:
hold on
i1 = [4.1 5.3];
for i=1:length(i1)
xline(i1(i)+1);
end
