The y-axis values in the plot function do not support enumerated data types. Refer https://www.mathworks.com/help/matlab/ref/plot.html for more information.
However, this can be made possible by using the yticklabels function in matlab. The enumerated data types can be defined by defining the class ‘BasicColors’ as follows.
classdefBasicColors < Simulink.IntEnumType
enumeration
Red(0)
Yellow(1)
Green(2)
end
end
Save the class as BasicColors.m file. Use the defined class in the below code to plot the enumerated data type along with the real floating point data type.
x = [1 2 3];
[~,y] = enumeration('BasicColors');
z = [25.2 25.9 67.9];
yticklabels(y)
yticks([0 1 2]);
ylim([0 2]);
yyaxis right;
plot(x, z);
