I am reading data from a folder with 9 s2p files that have S21 data that I am trying to plot. There are 3 temperatures I measured at and it is noted in the file name and is successfully sorted out. My issue is I want each temperature to have it's own color on the plot. My error is only present when I try to add color. I get the error "Error using rfdata.data/calculate>checkopcondition (line 1008) red is not a valid parameter or format."
the variable "data" is a single data variable and I am using the plot to just plot the S21 parameters
Why is the color not working?
for i=1:length(fileNames)
data = read(rfdata.data,name);
legend_name_real(i) = strcat(legend_name_real(i), temp50);
plot(data, 's21', 'db','color', 'yellow');
elseif contains(name,temp75)
legend_name_real(i) = strcat(legend_name_real(i), temp75);
plot(data, 's21', 'db','color', 'orange');
elseif contains(name,temp100)
legend_name_real(i) = strcat(legend_name_real(i), temp100);
plot(data, 's21', 'db','color','red');
legend_name_real(i) = strcat(legend_name_real(i), ' room temp');
plot(data, 's21', 'db','color', 'green');
legend(legend_name_real);
