The simplest way would be to use PairwiseScatterPlot if all pairwise 2-D views is sufficient. Depending on what "x,y,z,E-field" means (is that a physics or engineering thing?) having a single 3D scatter plot for x, y, and z with the size of the points proportional to the value in the "E-field" might be appropriate (or maybe proportional to the square or cube root of the E-field depending if the size of the point should be proportional to the diameter, area, or volume of the displayed "point").

And I've assumed you don't have thousands of points. What I've suggested probably gets a bit crowded with 200+ points (and maybe with fewer than that depending on how the points are distributed.)
