Dear all,

I am trying to use a boxchart for plotting a (10000,10) matrix, where each column represents a single box.
In other words, I would like to plot a boxchart consisting of 10 boxes and 10,000 data points.
The problem is that all Answers in the forum I have read so far are related to vectors, not matrices. All my attempts of using boxchart have resulted in an error, which states that I cannot use a matrix but vectors. Transforming the matrix into a vector is not possible. Additionally, I would like to group the 10 columns in 3 categories by assigning each box the respective color:

column [1 2 3 4 5 6 7 8 9 10]
group [A A B C C B A B C A]
color: [r r g b b g r g b r ]

However, I cannot provide a vector with values and tell Matlab to group the columns of the matrix on the basis of a specific threshold (e.g. temperature), but I have to do this manually by paper and pencil and inform Matlab which column belongs to which group myself.
I use the following code:

figure (2)

groupname={‘A’,’A’,’B’,’C’,’C’,’B’,’A’,’B’,’C’,’A’}’;
boxchart(AX.t_k,’MarkerStyle’, ‘none’,’GroupByColor’, groupname); % AX.t_k = (10000,10) matrix

And I get the following error:

Error using boxchart
‘GroupByColor’ parameter is not supported when the sample data argument is a matrix.

Could someone tell me, how I can use boxchart when using a matrix and how I can group each column with their respective color?

Thank you very much for your help!Dear all,
