I have two columns with c1 being a list of ages and c15 being if they earn more the 50k or less than 50k,(two categories).I was wondering how I could make a bar graph with the age as x axes (as a category) and a bar with a height corresponding to the % earning over 50k

for now all i have is this

c1 = CensusTrainTable{:,1}; 
c15 = CensusTrainTable{:,15};

How do I count the amount earned over 50 for just a specific age and then plot it?

Hi Andrej,

I'm assuming that you are trying to plot the ages of people with salary greater than 50K on X-axis and the amount by which the salary is greater than 50K on Y-axis. Try using the following code to do so:

% Convert the cell arrays to matrices
c1 = cell2mat(c1);
c15 = cell2mat(c15);
% Get the ages of people with income greater than 50K
c1 = c1(c15>50);
% Get the amount of income greater than 50K for the ages and save it as variable n
n = c15(c15>50)-50;
bar(c1,n);

Hope it helps!
