Axes can be drawn using built-in D3 functions. This is made of Lines, Ticks and Labels. The d3.axisRight() function in D3.js is used to create a vertical right-oriented axis. This function will construct a new right-oriented axis generator for the given scale, with empty tick arguments, a tick size of 6 and padding of 3.
Axis API can be configured using the following script.
<script src = "https://d3js.org/d3-axis.v1.min.js"></script>
Syntax:
d3.axisRight( scale )
Parameters: This function accepts only one parameter as mentioned above and described below:
- scale: This parameter holds the used scale.
Return Value: This function returns the created a vertical right-oriented axis.
Below programs illustrate the d3.axisRight() function in D3.js:
Example 1:
HTML
<!DOCTYPE html> <html> <head> <title> D3.js | d3.axisRight() Function </title> <script type="text/javascript" </script> </head> <body> <script> var width = 400, height = 400; var svg = d3.select("body") .append("svg") .attr("width", width) .attr("height", height); var yscale = d3.scaleLinear() .domain([0, 100]) .range([height - 50, 0]); var y_axis = d3.axisRight(yscale); svg.append("g") .attr("transform", "translate(100,10)") .call(y_axis) </script> </body> </html> |
Output:
Example 2:
HTML
<!DOCTYPE html> <html> <head> <title> D3.js | d3.axisRight() Function </title> <script type="text/javascript" </script> <style> svg text { fill: green; font: 15px sans-serif; text-anchor: start; } </style> </head> <body> <script> var width = 400, height = 400; var data = [10, 12, 14, 16, 18, 20]; var svg = d3.select("body") .append("svg") .attr("width", width) .attr("height", height); var yscale = d3.scaleLinear() .domain([d3.min(data), d3.max(data)]) .range([height - 50, 0]); var y_axis = d3.axisRight(yscale); svg.append("g") .attr("transform", "translate(100,20)") .call(y_axis) </script> </body> </html> |
