587d7fab367417b2b2512bd9 | Add Labels to Scatter Plot Circles | 6 | 301477 | Добавить ярлыки в круги кругов рассеяния |
Description
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.
Instructions
text
элементы. Текст метки должен быть двумя значениями, разделенными запятой и пробелом. Например, ярлык для первой точки - «34, 78». Установите атрибут x
чтобы он был на 5 единиц больше, чем значение, которое вы использовали для атрибута cx
на circle
. Установите атрибут y
же, как это используется для значения cy
на circle
.
Tests
tests:
- text: Your code should have 10 <code>text</code> elements.
testString: assert($('text').length == 10);
