I'm making a chart and im kind of confused. ill attach a photo below
So first off, I want the title to not be undefined, how do I change the title? And I want to change the background color of the chart below the lines, heres my code
{data?.length > 0 && (
<Line
options={options}
height={"300%"}
data={{
datasets: [
{
backgroundColor: "rgba(204, 16, 52, 0.5)",
borderColor: "#CC1034",
data: data,
}
]
}}
/>
)}
The legend label will be correctly displayed if you define label
on your dataset
, this was mentioned by WhiteHat in his comment.
In order to obtain the background color below the lines (basically an area chart), you need to add fill: true
to the dataset
.
To make it work, you also need to import and register Filler
from chart.js
.
Please take a look at this Code Sandbox and see how it works.
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} />;
}
