The code above creates the following graph, however i don't want the lines, i just need a scatter plot or marks of the data.

i have tried a few different options by doing

   \addplot [ 
color=black
marks only
mark=*
]

however it don't like the mark styles. i like the default black and white cycle list style that comes with the just \addplot command however it plots the lines too. i essentially would like the markers to have a solid outline and a grey fill

here is some of the data from one of the files, i am not sure how to attach a file, maybe someone can tell me that also

If you want to use the cycle list for colors and markers and to set option only marks as option for the \addplot command use

\addplot+[only marks]...;

Regarding the + see also Pgfplots Cycle List results in no Colors.

      \addlegendentry{Another legend entry}
    \end{axis}

Result

If all plots in the axis environment should use only marks you could set

every axis plot/.append style=only marks

as axis option:

The result is the same as above.

[Tex/LaTex] plotting two time series with bounds

This happens because PGFPlots only uses one "stack" per axis: You're stacking the second confidence interval on top of the first. The easiest way to fix this is probably to use the approach described in "Is there an easy way of using line thickness as error indicator in a plot?": After plotting the first confidence interval, stack the upper bound on top again, using stack dir=minus. That way, the stack will be reset to zero, and you can draw the second confidence interval in the same fashion as the first:

You can use

in the options of \addplot.
