I am having the follwoing issues:
I have a table with three variables: time in hours, altitude and solar activity, according to a time interval of 3hrs I have divided my data into 8 bins using the function discretize.
How can we plot the data within each bin indiviually, i.e we have 8 bins we would like to have a graph for each bin, that is for each interval of time, so at the end we get 8 graphs.
in the plot the data of each row sholud be presented for ex by a dot.
attached is a text file containing a sample of the data I am working with.

As per usual, would be easier to demonstrate with some real data to work with...but
tD=table(repmat([0:23].',4,1),randi([150 200]*1000,96,1),randi([10 70],96,1),'VariableNames',{'Hours','Altitude','Activity'});
tD.Bin=discretize(tD.Hours,8);
splitapply(@(x,y) plot(x,y,'*'),tD.Altitude,tD.Activity,tD.Bin)
xlabel('Altitude, ft')
ylabel('Activity, units')
tCenter=[1.5:3:24]; % bin time centers 0-3, 3-6, 6-9, ...
legend(compose('Time Bin %4.1f hrs',tCenter.')) % label by the group time centers
might be a fair starting point...

What I mean is that the plot here will display all the bins together in one plot. But what if we are interested in visualizing only the data within a certain bin. since the bins we have represents intervals of time, we would like the plot to plot only one specified bin i.e specified interval of time. would that be possible?

OK, here's another example; I'll add it as its own Answer -- carrying on from the above
uBin=unique(tD.Bin);
for i=uBin(:).'
nexttile
isBin=(tD.Bin==i);
scatter(tD.NE8(isBin),tD.GDALT(isBin),'.')
legend("Bin "+i,'Location','best')
xlabel('NE, units'),ylabel('GDALT, ft')
box on
end

Can you tell us which of the thumbnail pictures for the plotting functions included in MATLAB look closest to what you want to plot? If none of them do and you have other MathWorks toolboxes installed, open the Plots tab on the Toolstrip and see if any of the functions from a toolbox have thumbnails that look closer (maybe a boxplot from Statistics and Machine Learning Toolbox?)
