I am plot two set of data and I wanted to plot one set as dashed line but due to very high data points the dashed line is difficult to differentiate (see attached figure). Can you please suggest me how to visualise the dashed line better ?

You can plot them with different colors or with different markers. This would be better.
Other option is, you can skip some data points and then plot by dots.
skip = 2 ;
idx = 1:skip:length(x) ;
plot(x(idx),'.')

Thank you for your answer, changing colour and legend type will not help since I have too many data points. But your second suggestion is feasible in my case. But I did try but not able to skip the data. Could you suggest with my code please, Thank you
%plot of variables with data
plot(Ref_T,0.997*Ref_mwmg,'--')
hold on
plot(AR_T,AR_mwmg)
hold on
%plotx-y axis limit
xlim([50 580])
ylim([0.16 0.23])
%text
h=text(80,0.218,'Exo→')
set(h,'Rotation',90) %text rotation
%labeling the axis
legend('Base line','AR 5028')
xlabel("Temperature in C")
ylabel('Heat Flow in mW/mg (Exothermic→)')
