Hello everyone,
I am a new Matlab user. I have this table bellow:
trackID x y time
0 62.9926 -43.1079 2
2 81.2249 -69.9542 3
0 62.5516 -50.5776 1
3 125.7402 -64.7092 1.5
1 86.2224 -20.5914 2
0 70.1913 -37.885 4
I want to code/say that if the track ID is equal to 1 or 2 or 3 then plot scatter3 (x,y,time)
I am very new to Matlab, I truly appreciate your help or tips.
Thank you!

rowsToPlot = (t.trackID == 1) || (t.trackID == 2) || (t.trackID == 3)
x = t.x(rowsToPlot);
y = t.y(rowsToPlot);
z = t.time(rowsToPlot);
scatter(x, y, z);
grid on;
xlabel('x');
ylabel('y');
zlabel('time')

@Rulla RA you said "I have this table bellow:" so I assumed that was true and you had a table variable already. If you don't, just use readtable() like Star said above.
