EEG data plot issue

Hello ,when i plot my EEG dataset using code given below : my data gets plotted properly.

CG=load('1556openbci.mat')
LG=length(CG.chdata)
plot(CG.chdata)
xlabel('Time (s)'),ylabel('Amplitude (uV)'),xlim([0 60]), title(' Data') 

but if i add time vector of collected data in plot command as in code shown below my data seems to be very noisy...Can anyone please guide.

LG=length(CG.chdata)
TG=[0:LG-1]/fs
plot(TG,CG.chdata),xlabel('Time (s)'), ylabel('Amplitude (uV)'),xlim([0 60]), title('Data')

What is the issue?

@Saima Raza we cannot run your code without access to the data.

> my data seems to be very noisy

Is the problem that the data are noisy or is the goal to identify a way to visualize the noisy data?
