Gradient per bar or per pie part

[Martin]

Is it possible to get a different gradient on every bar or pie part?
Now it does 1 gradient for all the bars or pie parts within the chart.

And if it is possible, how do I do it?

Hi Martin,

I've fixed the problem with the Bar series and the gradient. This will be available with the next maintenance release.
We are currently investigating the problem with the Pie.

Hi again Martin,

The problem with the gradients in the Pie is more complex. It's actually that no polygon is being drawn with Gradients.
I've added it to the wish list to be further investigated (TF90016462).

Hi Yeray,

Can you tell me when that release is?
Or can you tell me what you have changed?
Then I can finish the project that I am working on.

Thanks a lot!

Hi Martin,

The Pie Gradients (TF90016462) haven't been fixed yet and I'm afraid I can't tell you a date for the Gradients for the polygons will be implemented, allowing this.

The fix for the Bar Gradients is enough simple to publish it here so you can apply it in your Chart.php.
Look for the setBrushCanvas function, and change it for this:

Code: Select all

    public function setBrushCanvas($aColor, $aBrush, $aBackColor) {
        $this->graphics3D->setBrush($aBrush);
        if ($aBrush->getGradientVisible()) {
            $this->graphics3D->getBrush()->getGradient()->setStartColor($aColor);
        }
        else {
            $this->graphics3D->getBrush()->setColor($aColor);
        }
    }
