How to change color of the plot when it is called in evalin function?

Hello everyone, I am trying to plot the variables from the workspace. I have to plot three different variables together on the same plot with different colors. My code looks likes this : try

    evalin('base',['plot(',a,',',x,')'])
    grid on
    hold on
    evalin('base',['plot(',a,',',y,')'])
    hold on
    evalin('base',['plot(',a,',',z,')'])
   catch ex
    errordlg(...
      ex.getReport('basic'),'Error generating linear plot','modal')
end

How can i make changes in evalin command so as to make plots of different color for each variable set. Please help

Can't you just add:

'color',someColour

to your evalin line in whatever is the correct syntax if you really have to use evalin? I've never used it myself, but judging from what you have done so far I don't see why just adding another couple of arguments to the plot function wouldn't work.

I get a syntax error when I try to run the first line of your code so I gave up on my attempt to get the right syntax for adding in the 'color' argument myself.
