Hi Richard,

Currently, the Bubbles in a Scatter chart always displayed with a gradient. I would however like to have it without gradient.
Is it possible currently somehow to create the bubbles without gradient? Otherwise can this been seen as an enhancement?

Regards,

Jan Dirk

Hi,

You'd have to alter the source at the moment - but I can add an option for it.

On or around line 2687 there's the line with just 'white' on it. This is where the gradient is being made. Chang this line to be exactly the same as the line beneath it. so the line looks like this:



obj.data[0][i][2] ? obj.data[0][i][2] : obj.properties['chart.defaultcolor'],



(with a comma at the end).

I have indeed altered the source for it, but I prefer not changing the RGraph sources, when possible.
I you could make an option for it, than that would be great. Otherwise I'll patch indeed the RGraph sources (with every new release I use).

Actually I changed

                        co.fillStyle = RG.RadialGradient(obj,
                             obj.coords[0][i][0] + (r / 2.5),
                             obj.coords[0][i][1] - (r / 2.5),
                             0,
                             obj.coords[0][i][0] + (r / 2.5),
                             obj.coords[0][i][1] - (r / 2.5),
                             r,
                             'white',
                             obj.data[0][i][2] ? obj.data[0][i][2] : obj.properties['chart.defaultcolor']
                         );

into

                         co.fillStyle = obj.data[0][i][2] ? obj.data[0][i][2] : obj.properties['chart.defaultcolor'];

Hi there,

OK I've added a colorsBubbleGraduated option to facilitate this.
