How to change line color

[jonnjasperejoc]

Okay so after spending a lot of time searching and experimenting with the chart because the Docs and API wasn't helping at all, I discovered a very simple way to change the default color of the line/column chart, without using the getSeriesStyle and getDatumStyle, just simple add the color property on your data.

const data = React.useMemo(
    () => [
      {
        label: 'Series 1',
        data: [
          { primary: 'Oct', secondary: 10 },
        ],
        color: '#1f77b4'
      },
      {
        label: 'Series 2',
        data: [
          { primary: 'Oct', secondary: 5 },
        ],
        color: '#ff7f0e'
      },
      {
        label: 'Series 3',
        data: [
          { primary: 'Oct', secondary: 7 },
        ],
        color: '#ffff4d'
      }
    ],
    []
  )

hope this helps.

For those trying to do this in v3.0.0 with a bar graph or something you can use defaultColors option with array of colors like so...

<Chart
	options={{
		defaultColors: [ '#00ccff', '#008800', '#ddaacc', /*Array of colors*/ ],
		data,
		primaryAxis,
		secondaryAxes,
	}}
/>

Here's how I added styled to my chart:

function MyChart({}) {
  const { data } = useChartConfig({
    height: 200,
    grouping: "primary",
    dataType: "ordinal",
  });

  const getSeriesStyle = React.useCallback((series) => {
    // Based off my chart bars
    const colorPalette = {
      series1: "#354657",
      series2: "#5597e2",
      series3: "#28A96C",
      series4: "#d44401",
      series5: "#ffe65b",
      series6: "#ffab1b",
    };

    return {
      fill: colorPalette[series.label],
    };
  }, []);

  return <Chart data={data} getSeriesStyle={getSeriesStyle} />;
}

I found the docs super confusing and over complicated so I hope this helps.

getSeriesStyle={getSeriesStyle}

Hello, I tried your code, it did changed the color of the Series (Yellow), but what I want is the line color, any idea?

Can I use it with line or area charts? Also can you please tell which index represents which element? I want to set the fill, points, line colors
