How to do such plot? Thanks!

["Shuxia Yu" <ysxzh@163.com>]

Dear all,

I have a data set with the following format:

1.889730	-0.944860	-5.669180	-0.011924
2.834590	-0.944860	0.000000	0.005855
0.944860	0.000000	2.618500	-0.023102
1.889730	0.000000	5.615540	0.023313
.....
.....

The first three columns is the coordinate of a specific point, and the
fourth colomn is the value of the point.

I hope to plot those points in 3D space with the value presented by
different color, for example, bule for negative value and red for
positive, or from bule to red with gradual change.

I can not find a way to do so. Would you like to give me some
suggestions?

Thank you very much for your kindly help.

Best wishes,

Jinsong
