I wish to convert my Bathtub graph to data form, and plot it in excel.

Can anyone advice me how to export this graph data to excel? Thank you.

The code i used:

Fs = 10000;             
Rs = 100;               
sps = Fs/Rs;            
SNR = 30;              
Trise = 1/(5*Rs);      
Tfall = 1/(5*Rs);       
frameLen = 5000;        
Tx = commsrc.pattern('SamplingFrequency', Fs, 'SamplesPerSymbol', sps, 'RiseTime', Trise, 'FallTime', Tfall);
Tx.Jitter = commsrc.combinedjitter('SamplingFrequency', Fs);
Tx.Jitter.DiracJitter = 'on'; 
Tx.Jitter.DiracDelta = 0.5e-3*[-1 1];
Tx.Jitter.RandomJitter = 'on';
Tx.Jitter.RandomStd = 0.3e-3;
message = generate(Tx, frameLen);
channel = comm.AWGNChannel('NoiseMethod', ...
    'Signal to noise ratio (SNR)', ...
    'SNR', SNR, 'SignalPower', 1);
Rx = channel(message);
eyeObj = comm.EyeDiagram('YLimits', [-1.5 1.5], ...
    'SamplesPerSymbol', sps, ...
    'SampleRate', Fs, ...
    'SampleOffset', 0.004*Fs, ...
    'DisplayMode', '2D color histogram', ...
    'ColorScale', 'Logarithmic');
Error using comm.EyeDiagram
comm.EyeDiagram has been removed. Use eyediagram instead.
eyeObj.EnableMeasurements = true;
eyeObj.OverlayHistogram = 'Jitter';
eyeObj.ShowBathtub = 'Horizontal';
eyeObj(Rx);
show(eyeObj);
