I am being asked to put long string values as my X axis tick labels.

I tried other charting libraries, but this one overall has worked the best for my situation. I just cannot figure out what to do with the x axis labels.

I tried to create a separate div and map through the values underneath the chart, but I can't maintain the alignment between the chart and the values when there are more than 7 or 8 x axis values.

I had a tickFormatter function that cut the string at a certain number of characters/hid the overflow and was set at an angle on the x axis, but they still aren't happy with that.

This is my code currently and I feel like it is so close to being workable and I just wish that I could get the text to wrap onto more lines.

Working with SVGs is extremely confusing to me and I've tried to write functions that return SVG text elements as a custom tick, but I couldn't get it to work. Or when I pass something and it returns [object Object] as the label.

 const data = React.useMemo(() => {
 return orderOfItems?.map((claim, i) => ({
  Item: i   1,
  Claim: claim.split(" ").join("\n"),
  Reach: (
    incrementalReachSummary[claim]?.Summary_Metrics.Reach * 100
  ).toFixed(1),
}));
}, [orderOfItems, incrementalReachSummary]);

const tickFormatter = (value: string) => {
const limit = 10; // put your maximum character

if (value.length < limit) return value;
return `${value.split(" ").join("\n")}...`;
};

CodePudding user response：

You need to create a custom tick react component. Line breaks will not work. You will need to use multiple <tspan> components with correct dy or vertical position. Also increase the chart bottom so lines are not hidden.

Use payload.value to access the original value & create as many tspans required.

<XAxis tick={<CustomizedTick />} />

Example

function CustomizedTick(props) {
    const { x, y, stroke, payload } = props;
    return (
        <g transform={`translate(${x},${y})`}>
        <text x={0} y={0} dy={16} fill="#666">
          <tspan textAnchor="middle" x="0">
            Line 1
          </tspan>
          <tspan textAnchor="middle" x="0" dy="20">
            Line 2
          </tspan>
          <tspan textAnchor="middle" x="0" dy="40">
            Line 3
          </tspan>
        </text>
      </g>
    );
  }
