Changing the colour of an axis in v4

Axis Labels in v4

This example shows a line chart of stock closing prices over time, with clear labels for both the x-axis (“Date”) and y-axis (“Value”). It uses d3.csv to load time-series data, d3.timeParse to convert date strings, and d3.scaleTime and d3.scaleLinear to map data to screen coordinates. The line is drawn as an SVG path with d3.line, and the axes are rendered via d3.axisBottom and d3.axisLeft. Custom text elements are appended to label the axes, demonstrating how to add axis titles in d3 v4.

Line graph with gradient in v4

This example shows a line graph of stock closing prices over time, with the line colored by a vertical gradient that shifts from red to black to green based on price levels. The visualization uses d3.v4 to load CSV data, parse dates with `d3.timeParse`, and render an SVG path via `d3.line`. A `linearGradient` with multiple stop points is applied to the line’s stroke, and axes are added using `d3.axisBottom` and `d3.axisLeft`. The data is drawn from `data.csv` containing date and close values.

Formatted time labels for an axis with v4

This example shows a simple line chart of stock closing prices over time, using formatted and rotated date labels on the x-axis. The visualization is built with d3.v4 and rendered as an SVG. It parses dates from a CSV file using `d3.timeParse` and `d3.timeFormat`, applies the axis with `d3.axisBottom` and rotated tick text, and draws the line with a `d3.line` generator. The code follows the structure of a basic d3 line graph, with margins, scales, and data mapping defined explicitly.

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.

Rotated axis labels in v4

This example shows a simple line chart of stock closing prices over time, with the x-axis labels rotated at a steep angle to prevent overlap. The graph uses d3.csv to load the date and close value pairs from data.csv, then renders the line with d3.line and scales using d3.scaleTime and d3.scaleLinear. After drawing the axes with d3.axisBottom and d3.axisLeft, it applies a rotation transform of -65 degrees to the tick text, along with adjusted text anchoring, to make the dates readable.

Axis Styling

This example demonstrates how to customize the appearance of axes created with the d3-axis API in D3 v4, rendering SVG output. The chart shows a time-based scale on the x-axis spanning 2010–2012 and a linear scale on the y-axis ranging from 0 to 2 million. Customization is achieved through post-selection, where the code modifies generated axis elements by removing the domain path, styling tick lines with dashed strokes and gray color, and adjusting tick text positioning. A custom tick format prefixes the first value with a dollar sign and appends “million” while others use narrow non-breaking spaces. The code uses `d3.axisBottom`, `d3.axisRight`, `d3.scaleTime`, and `d3.scaleLinear`.

Axis Labels in v5

This example displays a line graph of stock closing prices over time, annotated with "Date" and "Value" axis labels. Built with D3 v5, it uses `d3.timeParse`, `d3.scaleTime`, `d3.line`, and `d3.axisBottom`/`d3.axisLeft` to render an SVG path and axes from a CSV dataset. The labels are added as SVG text elements positioned using margin and dimension calculations, demonstrating custom axis labeling in D3 v5.

Axis Labels in v6

This example shows a line chart of stock closing prices over time, with clear axis labels for both the x- and y-axes. The visualization uses d3.csv to load date and close values from a CSV file, then d3.scaleTime and d3.scaleLinear to map the data to SVG coordinates. The line is drawn with d3.line, and the axes are rendered using d3.axisBottom and d3.axisLeft. The code adds rotated text for the y-axis label and horizontally centered text for the x-axis label, demonstrating how to annotate axes in d3 v6.
