title: Point.dx()
|
|
---
|
|
|
|
A point's `dx()` method returns the delta (in mm) along the X-axis between this point and the point you pass it.
|
|
|
|
## Point.dx() signature
|
|
|
|
```js
|
|
float point.dx(Point point)
|
|
```
|
|
|
|
## Point.dx() example

|
|
```js
|
|
let { Point, points, Path, paths } = part.shorthand()
|
|
|
|
points.from = new Point(10, 10)
|
|
points.to = new Point(80, 70)
|
|
|
|
paths.line = new Path()
|
|
.move(points.from)

|
.line(points.to)
|
|
.attr("class", "dashed")
|
|
|
|
points.totop = points.from.shift(0,points.from.dx(points.to))
|
|
|
|
points.text_dx = points.from
|
|
.shiftFractionTowards(points.totop, 0.6)
|
|
.shiftFractionTowards(points.to,0.1)
|
|
.attr("data-text", points.from.dx(points.to)+"mm")
|
