I have a 84x4 table with columns class, p, h and time. I am trying to extract data one by one and plot using bubblechart so that it displays continuous like a movie. The code looks like the following given. But it does not work. Please suggest/help me.
for k=1:84
class1=class(k);
p=p(k);
h=h(k);
d1=time(k);
bubblechart(d1,h1,p1)
hold on
grid on
title(['p vs h at time = ',num2str(d1), 'days'])
pause(1)
end

%let T be the table
for k = 1 : height(T)
bubblechart(T.time(1:k), T.h(1:k), T.p(1:k));
grid on
title("p vs h at time = " + string(T.time(k)) + " days")
pause(1)
end

Thank you so much for replying. In my table (84x4), the 1st column is name categorized as class, 2nd column is time, 3rd and 4th column are values for variables p and h respectively. I have taken your code in here. I seem to get an error after the end of for-loop stating the following:
Error using tabular/dotParenReference (line xx)
Unrecognized table variable name 'time'.
I'll post my complete code. Perhaps I'm doing something wrong.
Also, I need to clarify the column class. It has names a1, 14 times, then b1 (14 times), c1 (14 times) and d1 (14 times). Can I parallely display bubble plot for a1, b1 c1 and d1 running parallel/together from 1 to 14?
All your help is much appreciated.
T=readtable('p_vs_h test.xlsx')
class=T(:,1);
time=T(:,2);
p=T(:,3);
h=T(:,4);
for k = 1 : height(T)
bubblechart(T.time(1:k), T.h(1:k), T.p(1:k));
grid on
title("p vs h at time = " + string(T.time(k)) + " days")
pause(1)
end

Maybe something like
T = readtable('p_vs_h test.xlsx')
class = T{:,1};
time = T{:,2};
p = T{:,3};
h = T{:,4};
for k = 1 : 14
bubblechart(time(k:14:end), h(k:14:end), p(k:14:end));
grid on
title("p vs h at time = " + string(time(k)) + " days")
pause(1)
end
