# --description--
2018-10-04 14:37:37 +01:00
You can add text to create labels for the points in a scatter plot.
2020-11-27 19:02:05 +01:00
The goal is to display the comma-separated values for the first (`x` ) and second (`y` ) fields of each item in `dataset` .
The `text` nodes need `x` and `y` attributes to position it on the SVG canvas. In this challenge, the `y` value (which determines height) can use the same value that the `circle` uses for its `cy` attribute. The `x` value can be slightly larger than the `cx` value of the `circle` , so the label is visible. This will push the label to the right of the plotted point.

Label each point on the scatter plot using the `text` elements. The text of the label should be the two values separated by a comma and a space. For example, the label for the first point is `34, 78` . Set the `x` attribute so it's `5` units more than the value you used for the `cx` attribute on the `circle` . Set the `y` attribute the same way that's used for the `cy` value on the `circle` .
2020-11-27 19:02:05 +01:00
# --hints--
Your code should have 10 `text` elements.
```js
assert($('text').length == 10);
```
2021-03-05 11:25:29 -08:00
The first label should have text of `34, 78` , an `x` value of `39` , and a `y` value of `422` .
2020-11-27 19:02:05 +01:00
```js
assert(
$('text').eq(0).text() == '34, 78' & &
$('text').eq(0).attr('x') == '39' & &
$('text').eq(0).attr('y') == '422'
);
```
2021-03-05 11:25:29 -08:00
The second label should have text of `109, 280` , an `x` value of `114` , and a `y` value of `220` .
2020-11-27 19:02:05 +01:00
```js
assert(
$('text').eq(1).text() == '109, 280' & &
$('text').eq(1).attr('x') == '114' & &
$('text').eq(1).attr('y') == '220'
);
```
2021-03-05 11:25:29 -08:00
The third label should have text of `310, 120` , an `x` value of `315` , and a `y` value of `380` .
2020-11-27 19:02:05 +01:00
```js
assert(
$('text').eq(2).text() == '310, 120' & &
$('text').eq(2).attr('x') == '315' & &
$('text').eq(2).attr('y') == '380'
);
```
2021-03-05 11:25:29 -08:00
The fourth label should have text of `79, 411` , an `x` value of `84` , and a `y` value of `89` .
2020-11-27 19:02:05 +01:00
```js
assert(
$('text').eq(3).text() == '79, 411' & &
$('text').eq(3).attr('x') == '84' & &
$('text').eq(3).attr('y') == '89'
);
```
2021-03-05 11:25:29 -08:00
The fifth label should have text of `420, 220` , an `x` value of `425` , and a `y` value of `280` .
2020-11-27 19:02:05 +01:00
```js
assert(
$('text').eq(4).text() == '420, 220' & &
$('text').eq(4).attr('x') == '425' & &
$('text').eq(4).attr('y') == '280'
);
```
2021-03-05 11:25:29 -08:00
The sixth label should have text of `233, 145` , an `x` value of `238` , and a `y` value of `355` .
2020-11-27 19:02:05 +01:00
```js
assert(
$('text').eq(5).text() == '233, 145' & &
$('text').eq(5).attr('x') == '238' & &
$('text').eq(5).attr('y') == '355'

```js
assert(
$('text').eq(6).text() == '333, 96' & &
$('text').eq(6).attr('x') == '338' & &

2020-11-27 19:02:05 +01:00
```js
assert(
$('text').eq(7).text() == '222, 333' & &
$('text').eq(7).attr('x') == '227' & &
