 3D Bubbles Transparency |

Hi Peter,
today I am trying to make the 3D bubbles transparent ( because some are hidden behind others )
I suppose it is somewhere in the call:
$layer = $c->addScatterLayer($x, $y, "$title", $perlchartdir::GlassSphere2Shape, 15, $c);
but all my tries failed so far.
Maybe it is not possible in the current version?
Can you please give an advice.
Thank you in advance

Hi Sinan,
Your code seems to have some error.
In addScatterLayer, the 6th parameter should be the fill color. If you would like the bubbles to be semi-transparent, you may use a semi-transparent color. However, in your code, you use $c as the 6th parameter, and $c is the chart object. This means you are using the chart object as the color of the bubble, which is not meaningful.
May be you can try:
$layer = $c->addScatterLayer($x, $y, "$title", $perlchartdir::GlassSphere2Shape, 15, 0x80ff3333);
You should see the bubbles become semi-transparent.
Hope this can help.
Regards

Hi Peter,
I've shortened the arguments in the request to make the line shorter. The original code in fact has correct color codes but only 3 bytes (for example 0xabcdef) - In the same moment when I red your response, I remebered - the fourth byte makes the transparency. Great, incredible, Thank you

| oops, for the readers of this question: it is the first byte in a 4byte colorcode that defines the transparency. |
