Still not fixed.
I got a workaround for this using a formatter.
**Function which takes string and maxWidth as parameters and imitate
maxWidth by using real dom element and calculate when to break string using
`\n`.**
```js
function wrapTextToPixelWidth(
text: string,
maxWidth: number,
font = '12px Arial',
) {
const span = document.createElement('span');
span.style.visibility = 'hidden';
span.style.whiteSpace = 'nowrap';
span.style.position = 'absolute';
span.style.font = font;
document.body.appendChild(span);
const words = text.split(' ');
let currentLine = '';
let result = '';
words.forEach(word => {
const testLine = `${currentLine + word} `;
span.textContent = testLine;
const testLineWidth = span.offsetWidth;
if (testLineWidth > maxWidth) {
result += `${currentLine.trim()}\n`;
currentLine = `${word} `;
} else {
currentLine = testLine;
}
});
result += currentLine.trim();
document.body.removeChild(span);
return result;
}
```
Then in the formatter function:
```js
axisName: {
formatter: (value: string) => wrapTextToPixelWidth(value, 140),
},
```
