Is this a Spectrogram of a particle in its waveform?!

No,

they have in one axis energy of photon (or frequency, or wavelength),

and in second axis some other measured quantity.

Did you click the link? They say this:

 

We have developed a novel, all-optical technique to measure the complete waveform of arbitrary optical pulses with attosecond temporal resolution based on high harmonic generation (HHG).

I have feeling that you misunderstood "waveform of optical pulse"..

 

Easier example is pulse of LED (Light Emitting Diode).

1 Hz pulse. 0.5 second it's turned on, 0.5 second it's turned off.

It could be millions or billions of photons in each pulse, not single photon particle.

 

Compress 1s, or 0.5s pulse, in my "home made" example, to 10^-18 second (attosecond),

and you will have ultrashort pulse.

https://en.wikipedia.org/wiki/Ultrashort_pulse

It still could have tremendous quantity of photons emitted at almost the same time.

Tell me you clicked the link and then I'll believe you.

 

 

I clicked the link. And even read the article. This is nothing to do with the "spectrogram of a particle in its waveform" (whatever that means) but is about generating high frequency pulses and sampling their spectrum. This is probably something that swansont would understand far better than me...
