how to plot shorter dataset using 'hold on'

Hi,

I have a dataset and want to plot a line of best fit to the beginning of the data which is the only part where it fits.

Currently, I have the lines of code:

scatter(T5half,logconductivity5(2:end))

hold on

y=-21.05*T5half-25.18

plot(T5half,y)

Does anyone know how to do this?

Thanks.

Is this what you need?

desired_range = 1:200;  % here, select the array positions you want to plot
plot(T5half(desired_range),y(desired_range))
