I have 2 vectors, for example I`ll show the basic point scattering on a plot
amp1=[4.59200000000000e-05;5.82746666666667e-05;3.73920000000000e-05;2.93013333333333e-05;1.47600000000000e-05]
dc_voltages=[127.300000000000,138,66.4000000000000,78,96.4000000000000]
plot(dc_voltages,amp1,'x')
so I get:
scatter1.png
I want to connect those dots such that I will get the picture:
scatter1_2.png
but when I try:
plot(dc_voltages,amp1,'--x')
I get:
scatter3.png
I don`t use cftool because I have to fit a lot of similar graphs in the same figure.
Please help

Sort ‘dc_voltages’:
[~,idx] = sort(dc_voltages); % Sorts Ascending By Default
figure
plot(dc_voltages(idx),amp1(idx),'--x')
Only the order has changed.
