No colors with Obsidian Charts dataviewjs query

Got same problem here.
I found that obsidian-charts only adds the default colors when parsing yml.
Thus, I managed to work around with something like

const labels = [];
const tagPages = dv.pages('#fixkosten');
const kosten =[];

tagPages.forEach(note => {
    // add the name of the note
    labels.push(note.file.name);
    // add the word count for the note
    kosten.push(note.Entspricht);
});

dv.paragraph(`\`\`\`chart
	type: 'doughnut'
	labels: ${labels}
	labelColors: true
	series:
	- data: ${kosten}
\`\`\``)

If you really want to use window.renderChart, you may consider building your own obsidian-chart plugin with dependency chart.js ^4.0.0, then you will get some default colors from chart.js.
