This D3.js v4 example shows a dual-axis line-bar chart comparing two line series with a bar series across five yearly data points. The visualization combines steelblue and crimson lines, overlaid with labeled circles on each point, alongside gray bars on a shared x-axis. The code uses `d3.scaleBand` and `d3.scalePoint` for the x-positions, `d3.scaleLinear` for the separate left and right y-axes, and `d3.axisLeft` and `d3.axisRight` to render them. Data is loaded from a local CSV file and rendered as SVG elements.

AI-generated description

This is a multiple line graph demonstrating the display of seperate colour coded y axes for each line. This was written using d3.js v4 and is a follow on to the multiple line graph example here.

This graph is part of the code samples for the update to the book D3 Tips and Tricks to version 4 of d3.js.

Dual axes in v5

A dual-axis line chart plots two time series from a CSV file, with one line in steel blue and another in red, each paired to its own y-axis. The example uses D3 v4 with `d3.scaleTime`, `d3.scaleLinear`, `d3.line`, and `d3.axisBottom`, `d3.axisLeft`, and `d3.axisRight` to render an SVG. The steel-blue axis appears on the left, the red axis on the right, and both lines share a common time-based x-axis. The styling is driven by CSS classes for axis text colors, as shown in the index.html file.

Dual axes in v5

This chart displays two time-series lines from a CSV file, each with its own color-coded y-axis. The steel blue line represents closing values on the left axis, while the red line shows opening values on the right axis, allowing comparison of differently scaled data. Built with D3 v5, the code uses `d3.line`, `d3.scaleTime`, `d3.scaleLinear`, `d3.axisBottom`, `d3.axisLeft`, and `d3.axisRight` to render the SVG paths and axes. The axes and line colors are coordinated through CSS classes.

Dual axes in v7

This example displays two line charts sharing a common time axis, with each line assigned its own colored vertical scale: a steelblue line for the "close" values on the left axis and a red line for the "open" values on the right axis. It uses the d3.v7 library, specifically the `d3.line` generator, `d3.scaleTime`, and two `d3.scaleLinear` scales. Data is loaded from a local CSV file via `d3.csv`, with dates parsed using `d3.timeParse`. The SVG output renders the paths and axes with custom CSS classes for axis-label coloring.

Count + Percent

This example demonstrates a dual-axis chart combining bar and line representations. Gray bars show raw counts by year on a steelblue left axis, while a steelblue line with points displays percentage data on a crimson right axis. The visualization uses D3 v4 with SVG rendering, employing `d3.scaleBand` for the categorical x-axis, `d3.scaleLinear` for both y-axes, and `d3.axisBottom`, `d3.axisLeft`, and `d3.axisRight` to generate the axes. Data is loaded from a local CSV file.

Basic bar+line chart

This chart combines a bar chart and a line chart in a single SVG visualization, with bars representing one data series and a line overlaid for a second series. It is built as a reusable template driven by a CSV file, where column names for the x-axis, bar values, and line values are configured in the code. The x-axis uses a band scale for categorical years, while the y-axis is linear and shared by both series. Blue bars show the primary values, and a green line connects the secondary values, with a legend distinguishing the two. The chart includes axis labels, a title, and a hover effect on the bars.

Dual axes in v6

This example shows two time-series lines from a CSV file with date, close, and open values, each with its own colored y-axis: steelblue for the close values on the left and red for the open values on the right. The chart uses D3 v6’s `d3.scaleTime` and `d3.scaleLinear` for axes, `d3.line` to generate the SVG path data, and `d3.axisLeft` and `d3.axisRight` to render the separate scales. The data is loaded via `d3.csv` and parsed with `d3.timeParse` before being drawn as SVG paths within a single group element.

Simple d3.js bar chart

This simple d3.js bar chart displays monthly values over a two-year period, with each bar representing a data point from a CSV file. The visualization uses d3.scale.ordinal and d3.scale.linear to map categorical dates and quantitative values, respectively, to pixel positions. Axes are rendered with d3.svg.axis, while the bars themselves are drawn as SVG rectangles with a steelblue fill. The chart includes a navigation interface with circular arrow buttons and a detail area, though the interaction logic is incomplete. Data comes from the external file bar-data.csv, and the visualization is built using the D3 version 3.5.17 library.

sync candlebar and line, 2-y-axis

This example syncs a candlestick chart of stock price data with a line chart of returns, using two separate y-axes. The left axis shows price (Open, High, Low, Close) via red and green candles for up and down days, while the right axis displays a steelblue line for the return ratio. Built with D3 v4, it uses `d3.scaleTime`, `d3.scaleLinear`, `d3.line` with `d3.curveBasis`, and `d3.axisRight`/`d3.axisLeft`, rendering as SVG from a CSV file. The legend and axis labels clarify the dual metrics.
