A log-scale axis displays powers of ten from 10⁰ to 10⁹, with tick labels formatted using superscript characters (⁰¹²³⁴⁵⁶⁷⁸⁹) via a custom `formatPower` function that maps each digit to its Unicode superscript equivalent. The example uses d3.v3's `d3.scale.log` and `d3.svg.axis`, with tick formatting defined by a custom function passed to `.ticks(10, ...)`. The SVG rendering places the axis with generous top and bottom margins, and the code notes the vertical alignment issue between superscripts and normal digits.

AI-generated description

Perhaps not the best approach due to the inconsistent vertical positioning of ¹²³ vs. the other numbers… Alternatively, you could use axis post-selection to achieve the same effect.

Superscript Format II

A log-scaled axis spans from 10⁻⁴ to 10⁴, with tick labels that display only the number 10 for each power of ten. The code uses d3.svg.axis for the axis, then post-selects tick text elements, filters for powers of ten, and appends a tspan for the superscript exponent. The exponent is computed from the tick value using Math.log and rendered with a smaller font size via CSS. This approach creates a clean, typographically precise axis label alternative to Unicode superscripts.

Natural Log Scale

A natural-logarithmic y-axis displays a polynomial curve from x=0 to 100, with tick labels formatted as "e⁰" through "e⁹" using Unicode superscripts. The example uses d3.v3 with `d3.scale.log` and `d3.svg.axis`, applying a custom `tickFormat` that converts log values to superscript exponents. The line is drawn with `d3.svg.line`, while the SVG output includes styled axis text and a steelblue path. The data series is generated procedurally as `[x, x²+x+1]` for 100 points.

Tick Format

This example compares three ways to format tick labels on linear axes, each rendered as an SVG axis via `d3.axisLeft`. The left axis uses `scale.tickFormat` with an SI-prefix type (`"s"`), producing a consistent prefix across all ticks. The middle axis applies `d3.format(".0s")` directly, causing variable precision and prefix per label. The right axis uses `d3.formatPrefix(".1", 1e6)` to enforce a fixed mega-prefix, demonstrating manual control over SI formatting. The three axes share the same domain from -1e6 to 2e6.

Log Axis

This example demonstrates a log-scale axis using a hard-coded domain from 0.0124123 to 1230.4, rendering tick labels with the `",.1s"` format. The visualization uses d3.v3’s `d3.scale.log` to create the logarithmic scale and `d3.svg.axis` to draw the axis with 20 ticks. The SVG output is positioned within a larger canvas using margins, and styled with CSS for font and stroke. The code does not include a data source, as it focuses solely on the axis component.

Fork of D3 Axes - Tick Label Formatting

This example demonstrates how to format tick labels on a D3.js axis using custom tick formatting. A linear scale maps a domain of 0 to 100 to a pixel range, and an axis bottom is configured with increased tick padding and size. The axis is customized by limiting the number of ticks to four and applying a custom `tickFormat` function that appends a percent sign to each value. The resulting SVG renders the axis with labeled ticks showing the original data values with a “%” suffix.

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`.

Custom Time Format

This example demonstrates a custom multi-scale time format for a D3 axis, showing how tick labels adapt to different time granularities—displaying milliseconds, seconds, minutes, hours, days, and months as the scale zooms. It uses `d3.time.format.multi` to define an array of format/filter pairs, applied via `d3.svg.axis`. The code generates an SVG chart with a single year-long domain, rendering tick labels dynamically based on the date’s precision. The data source is the current date, and the rendering relies on D3 v3’s SVG axis API.

Classical Scales

This visualization showcases a comprehensive set of D3.js v2.10 scales through a series of horizontal axes, each paired with a descriptive label. Linear, logarithmic, power, square-root, quantile, quantize, threshold, and identity scales are demonstrated, with the log and power scales shown across different domain ranges to illustrate their behavior. The example also highlights tick subdivision options, including numeric, boolean, and string arguments, which is particularly notable because vanilla D3 v2.10 does not support function-based parameters for tick subdividing. The SVG renderer displays the axes with a glowing filter effect and the layout is fixed to 1500 pixels in height to accommodate the many examples.
