3D Bubble Chart color problem

Oct 28, 2014 at 2:11 PM
Hi, I really need help on this.
So, the problem is I want a 3D Bubble in HighChart effect, but can't vary the color when defining plot options.
.SetPlotOptions(
                  
                    new PlotOptions
                    {
                        Bubble = new PlotOptionsBubble
                        {
                            Marker = new PlotOptionsBubbleMarker
                            {
                                
                                LineColor=null,
                                 FillColor= 
                               new BackColorOrGradient(
                                  new Gradient
                                        {
                                          RadialGradient = new RadialGradient { Cx = 0.4, Cy = 0.3, R = 0.7 },
                                           
                                          Stops =
                                           new object[,]
                                           {
                                               {
                                                   0,"rgba(255,255,255,0.5)" },
                                               {
                                                1, ?
                                               }


                                            }
                                      })
        
                            }
                        }
                    })
the ? mark should be the same with my line color series and auto provide by highchart.
for info, i have about 6 series data from sql.

how can it be done?

thx..
