I have a matrix of data. I used the [`polarplot`](https://www.mathworks.com/help/matlab/ref/polarplot.html) command in MATLAB to plot this matrix with respect to theta.

The data oscillates between 3999.20 and 4001.52 As you can see in the following plot, the order of magnitude of oscillation of data is too small to see. 

How can I modify my polar plot to see small oscillations?

My code is as below:

```
yf=[%750 data point]
theta = 0:4*pi/749:4*pi;
rho = yf
pax = polaraxes;
polarplot(theta,rho)
pax.ThetaDir = 'counterclockwise';
pax.ThetaZeroLocation='right'
pax.ThetaColor='r'
pax.ThetaTick=[0 30 60 90 120 150 180 210 240 270 300 330 ];
pax.RDir='normal';
pax.RTick=[3999.34 3999.67 4000 4000.33 4000.66 4000.99 4001.33 ]
pax.FontSize = 12;

```

Desired output:
---------------
