change histogram color in matlab

To change the color of a histogram plot in MATLAB, you can use the histogram function's 'FaceColor' property. Here is an example code:

main.m
% create sample data
data = randn(1000,1);

% plot histogram with blue color
histogram(data,'FaceColor','b');

% plot histogram with green color
histogram(data,'FaceColor','g');
178 chars
9 lines

In this example, the histogram function is used to plot a histogram of the data variable. The color of the histogram is set by using the 'FaceColor' property with either 'b' for blue or 'g' for green. You can use any valid color string to set the color of the histogram.

You can also use RGB triplet values for custom colors. For example:

main.m
% create sample data
data = randn(1000,1);

% plot histogram with custom color
histogram(data,'FaceColor',[0.5 0.5 0.5]);
122 chars
6 lines

This will plot the histogram with a custom gray color specified by the RGB triplet [0.5 0.5 0.5].
