Need some explanation about xray flux and other graphs!

Here is the link to the Noaa data

There are many graphs but the graphs that i'm interesting in are the the xray flux graph and the one below it.

From what i've been looking it seems the xray flux graph shows the electromagnetic radiation emanating from the sun (xrays) but why on earth are there two lines a red one and a blue one???

And what exactly is this type of radiation heat or just small particles like electrons or neutrons?

Also is this radiation interacting with the magnetosphere or can it go beyond it and reach our atmosphere!

What i also would like to know is the function of the graph below it from what i understand i read teslas so this might indicate the strenght of our magnetic field if so why on earth are there two lines red and blue depicting it?

Any astronomer around?

I would also apreciate if further explanation is given for the other graphs next to it but this is less important than the xray flux and the one below it.
