how do I place the text on the first co ordinate of the plot?

1 view (last 30 days)
I am potting trajectories of vehicles (time-space plots) and following is my code %% Read data table = readtable('E:\vehdata11.xlsx'); VehicleNos = unique(table.VehicleID);
%% Plotting
for idx = 1:numel(VehicleNos) n = VehicleNos(idx); sb = table(table.VehicleID == n,:); labels=cellstr(num2str(n)); Time= sb.time; x = sb.time; y = sb.x; tin = min(x); t1 = x - tin; y1 = t1*11.04; y2 = y - y1;
%% plotting for time interval
i = (Time>20 & Time<=25);
hold on
end Now the position of text is on the maximum (x,y) coordinate But since my graph is not linear and fluctuating I want the labels to be on the first co ordinate text(x(1), y(1),labels) is not working. How do I do that?

What error do you get? Or what do you mean "is not working"? Check the values of x(1) and y(1) and make sure they're not NaN or outside your graph axis.

I assigned x=x(i) and y=y(i) and then used text(x(1),y(1), labels).It says index exceeds matrix dimensions and also shows error in text command.
