Changing live uitable row colours depending on value.

I'm using a live uitable object to read out data from an Arduino and write it into a table, using a callback function. I want give the rows a specific color, depending on the value in one of the columns. I did get it to work with addStyles, but I noticed that this command significantly slows down my code, to the point where it's not useable to me. Is there another way to do this, for example by changing a table property?

Since you are coloring by row, setting the uitable's BackgroundColor may work for you.

You can use a matrix of colors. Example:

figure
t = uitable('Data',randi(10,4,3));
t.BackgroundColor = [1 0 0; 1 1 0; 0 1 0; 0 1 1];

If the table has more rows than there are rows in BackgroundColor, then the colors are repeated as necessary:

figure
t = uitable('Data',randi(10,4,3));
t.BackgroundColor = [1 0 0; 1 1 0; 0 1 0; 0 1 1];
t.Data(end+10,:) = 0;

Alternatively, you may be able to speed up your code that uses addStyle if you make sure to removeStyle any uistyle when it is no longer needed.
