How to skip first chart color? #2952

Open GHSix opened this topic on on Jan 18 - 2 comments

Hi. I have this two connected D3 charts but, the first chart have one value more and I want this value to be the first one for normalization purposes. Now, the rest of the values are the same but are now with different colors and I would like them to be the same.

So, is there a way to skip the first color (red) in the second chart in the automatic color scheme?

Yes you can, you do this to remove the first color in your chart:

use \koolreport\dashboard\ColorList;

class MyChart extends BarChart
{
    protected function onCreated()
    {
        $this->colorScheme(array_shift(ColorList::default()));
    }
}

The array_shift() methods will remove the first color in the default color list.

To avoid Only variables should be passed by reference error, I had to

$cl = ColorList::default();
$this->colorScheme(array_shift($cl));

But then I got different colors, probably because I'm using AppStack theme, but I can't figure out how to make it right since it looks like the ColorList::default is, indeed, holding the colors the AppStack uses.

I goi it right by doing like this:

->colorScheme([
                '#6EE05A',
                '#BC5AE0',
                '#E0DE5A',
                '#5ABAE0',
            ])

But I got puzzled on the why ColorList::default didn't work as expected.
