Multiple line Style on a yyaxis plot

I've plotted data from several tables in dat files on a yyaxis plot using:

S=["10D.dat","12D.dat","15D.dat","19D.dat","21D.dat","24D.dat","27D.dat","45D.dat","63D.dat","90D.dat","105D.dat"];
for k =1:numel(S)
    T= readtable(S(k),"VariableNamingRule","preserve");
    T = renamevars(T, ["Var1", "Var2", "Var3", "Var4"], ["Time","Ts","Rd", "Teff"])
    yyaxis left
    plot(T.Time, T.Rd)
    yyaxis right
    plot(T.Time, T.Ts)
    hold on
end
grid on
yyaxis left
xlabel('Time [ms]')
ylabel('Droplet Radius [um]')
title('Pure Diesel')
yyaxis right
ylabel('Tempreture [K]')

However, My plot comes out like this:

But because there are so many data sets, some of the lines have markers in, making the plot difficult to read.

Is there a way of making all of the lines some varient of dashed?? I'm not bothered about colour.

And how can i get the legend to display just one set of 10-105??
