+title: Path.setText()
+---
+
+The `Path.addText()` method set text on the path.
+
+## Signature
+
+```js
+Path path.setText(string text, string className)
+```
+
+The second argument will optionally be used to set the CSS class for the text.
+
+<Tip compact>This method is chainable as it returns the `Path` object</Tip>
+
+## Example
+
+<Example caption="Example of the Path.setText() method">
+```js
+({ Point, points, Path, paths, part }) => {
+  points.from = new Point(5, 10)
+  points.to = new Point(95, 10)
+
+  paths.line = new Path()
+    .move(points.from)
+    .line(points.to)
+    .addText('FreeSewing rocks')
+
+  return part
+}
+```
+</Example>
+
+## Notes
+
+The main purpose of this method is to save your some typing,
+as the two following calls yield the same result:
+
+```js
+path.attr('data-text', 'Hello')
+path.setText('Hello')
+```
+
+The difference with [Path.addText()](/reference/api/path/addtext) is that this
+method will overwrite existing text on the path, whereas `Path.addText()` will
+add to the existing text.
