MATLAB: Two y-axis colors

2 y axescolors

Hello, and thanks for the help given to me earlier.
I have created — thanks to MATLAB help — a graph with two y axes. The default colors appear to be blue and red. Is there a way that I can make all the lines and labels black? I can't seem to find that way anywhere.
Many thanks.
Lynn

Assuming you did something similar to the code below, you can access the axis properties directly and change the color to whatever you want.
% Create a figure and axis with 2 Y axes
figure;
ax = axes; % or ax = gca();
yyaxis('left');
yyaxis('right');
% Set the color of each axis to black
ax.YAxis(1).Color = [0 0 0];
ax.YAxis(2).Color = [0 0 0];
