VADC output graph looks weird in XMC4500

[#1]

Hi,
I have generated a project to obtain high sampling rate of VADC using XMC4500-F100x1024 Relax Lite Kit. But the output graph I generated seems like the sampling is not good enough..Can anybody tell me
what I did wrong in the VADC settings. I am hereby attaching my VADC settings as well as some screenshots of the output graph.

Thanks in advance...

Which channel is which signal?

For example, what is the original signal shape?

Hi Aurixuser,
CH2 is actually what I am moitoring..Rightnow sine wave signal is connected to that channel..the frequencies i mentioned in the pictures are what i connected from a signal generator to the corresponding
VADC pin..Actually, if i connect the input from functionn generator to any four VADC channels that i am using will give me the same output graphs..From my observation what i can see is while using
four stage FIFO in VADC and if i enable result event after the 4th conversion , all the four result registers contains the same result even though the input signal frequency is too high.

Thanks in advance...
