--- id: 587d7faa367417b2b2512bd2 title: Add Labels to D3 Elements challengeType: 6 forumTopicId: 301476 dashedName: add-labels-to-d3-elements --- # --description-- D3 lets you label a graph element, such as a bar, using the SVG `text` element. Like the `rect` element, a `text` element needs to have `x` and `y` attributes, to place it on the SVG canvas. It also needs to access the data to display those values. D3 gives you a high level of control over how you label your bars. # --instructions-- The code in the editor already binds the data to each new `text` element. First, append `text` nodes to the `svg`. Next, add attributes for the `x` and `y` coordinates. They should be calculated the same way as the `rect` ones, except the `y` value for the `text` should make the label sit 3 units higher than the bar. Finally, use the D3 `text()` method to set the label equal to the data point value. **Note:** For the label to sit higher than the bar, decide if the `y` value for the `text` should be 3 greater or 3 less than the `y` value for the bar. # --hints-- The first `text` element should have a label of `12` and a `y` value of `61`. ```js assert($('text').eq(0).text() == '12' && $('text').eq(0).attr('y') == '61'); ``` The second `text` element should have a label of `31` and a `y` value of `4`. ```js assert($('text').eq(1).text() == '31' && $('text').eq(1).attr('y') == '4'); ``` The third `text` element should have a label of `22` and a `y` value of `31`. ```js assert($('text').eq(2).text() == '22' && $('text').eq(2).attr('y') == '31'); ``` The fourth `text` element should have a label of `17` and a `y` value of `46`. ```js assert($('text').eq(3).text() == '17' && $('text').eq(3).attr('y') == '46'); ``` The fifth `text` element should have a label of `25` and a `y` value of `22`. ```js assert($('text').eq(4).text() == '25' && $('text').eq(4).attr('y') == '22'); ``` The sixth `text` element should have a label of `18` and a `y` value of `43`. ```js assert($('text').eq(5).text() == '18' && $('text').eq(5).attr('y') == '43'); ``` The seventh `text` element should have a label of `29` and a `y` value of `10`. ```js assert($('text').eq(6).text() == '29' && $('text').eq(6).attr('y') == '10'); ``` The eighth `text` element should have a label of `14` and a `y` value of `55`. ```js assert($('text').eq(7).text() == '14' && $('text').eq(7).attr('y') == '55'); ``` The ninth `text` element should have a label of `9` and a `y` value of `70`. ```js assert($('text').eq(8).text() == '9' && $('text').eq(8).attr('y') == '70'); ``` # --seed-- ## --seed-contents-- ```html ``` # --solutions-- ```html ```
