plot two matrices against each other

I'm trying to plot these values

xvalues=[64.5 65 67.5 69.3 71.2 73.1 75.3 78 81.7 84.4 87.7 89.3 91.2 93.5 96.4 100];
yvalues=[1 0.9790 0.958 0.915 0.870 0.825 0.779 0.729 0.665 0.579 0.517 0.418 0.365 0.304 0.23 0.134 0];
yvalues2=[1 0.95 0.9 0.8 0.7 0.6 0.5 0.4 0.3 0.2 0.15 0.1 0.08 0.06 0.04 0.02 0];

So that it looks like

Answer 1

plot(xvalues, yvalues, 'ks', xvalues, yvalues2, 'ks')

[savannah Roemer]

That helps, Thank you! I just added 'k--s' and I think that'll work :)
