Bar Graph Colors in GUI

I have a GUI (made with GUIDE) that has a set of axes and some radio buttons. When it open it loads some data and pressing the radio buttons will plot the data in different ways (mean, standard deviation, histogram). I plot the histogram using the bar() command, and I put in a matrix of data where each column is data from a different day.

When the first plot I select to be displayed is the histogram, the colors come up correctly where the data from each column has its own color. The same happens when I just open up a new figure and pass the data into bar(). If I select one of the other plots first (mean, standard deviation), which just does a plot(), and then flip back to histogram then all the bars come up with the same color.

The code I use to plot (in the function update_plot()):

    axes(handles.axes1);
    bar(t,hist_data);
    legend(legends);

where t is a vector of bin centers and hist_data is a matrix of the histogram values in each bin (rows) by the multiple days (columns) data was loaded from.

I have tried digging through the axes handles to see if there was an obvious parameter that was set wrong, but I couldn't spot anything.

The GUI and some dummy data is attached in a .zip file.

Kris - you may need to attach your GUI or at least a small working sample that exhibits this behaviour so that we can see exactly what the code is doing.

GUI attached. If you see anything funky in there, please let me know!

histogram() no longer does histograms by columns like it sued to do in older versions. It takes the histogram of the entire array. (I didn't download your code so I'm not sure if you used that or histcounts or hist or histc.)

I used hist to get the bin centers and counts and then plot those using bar.
