Yahoo Finance Chart Step 10 - Crosshair

Yahoo Finance Chart

This example visualizes intraday stock price data from Yahoo Finance using a combination of D3 and d3fc components. The chart displays high, low, open, and close prices, along with trading volume and a moving average, over a discontinuous time scale that skips non-trading hours. A crosshair tooltip shows detailed values for the hovered data point, while callout annotations highlight the most recent high and moving-average values. Trading hours are marked with vertical annotations and shaded bands, and the chart includes a legend summarizing the OHLC and volume data. The visualization uses an SVG renderer and is built with d3.v5, demonstrating how to compose multiple series and annotations using the d3fc library.

Yahoo Finance Chart Step 13 - Vertical Bands

This visualization shows a Yahoo Finance candlestick chart with a high-low range area, a 20-period exponential moving average, and volume data, with trading hours handled via a custom discontinuity scale. The chart uses d3fc components for the time-series layout, annotation lines, and legend, while the crosshair feature displays tooltip callouts for price and time values. Data comes from a Yahoo Finance JSON feed and is filtered to regular trading hours, with the full SVG rendered using D3.js.

Yahoo Finance Chart Step 8 - Callouts

This example demonstrates a Yahoo Finance chart of stock prices, using an area and line series to show the opening price over time, with a red moving average line overlaid. The chart uses D3.js with the d3fc library, rendering to SVG. It highlights the final values of the close price and the exponential moving average using styled callout annotations with labels. The data is loaded from a CSV file, and volume bars appear below the main time series, colored red or green based on price movement.

Yahoo Finance Chart Step 12 - Discontinuous Axis

A Yahoo Finance stock chart displays OHLC (open, high, low, close) data as a time series, with an exponential moving average (EMA) overlay and a volume subplot. The example uses a discontinuous axis via the `fc.scale.discontinuity.tradedHours` provider from the d3fc library, which compresses non-trading hours. Built with D3.js (v3.5.5) and d3fc, it renders SVG elements, including an area gradient, line annotations, and crosshair callouts. Data is loaded from a static `yahoo.json` file, with the time axis filtered to trading hours (7 AM–7 PM).

Yahoo Finance Chart Step 3 - Styling

This example shows a styled financial time-series chart of Yahoo Finance stock data, plotting opening prices as both a line and an area chart over a single trading day. The SVG rendering uses the d3fc library’s `linearTimeSeries` chart, with `area`, `line`, and `gridline` series composed via `multi`. A custom CSS gradient fills the area, while axis labels are repositioned and bolded for readability. Data is loaded from a CSV and parsed into JavaScript `Date` objects using `d3.csv`.

Yahoo Finance Chart Step 9 - Legend

This example shows a Yahoo Finance time-series chart of stock price data, displaying open, high, low, close, and volume values with a moving average line, price callouts, and a legend. It uses the d3fc library's `fc.chart.linearTimeSeries` and `fc.chart.legend` APIs, along with D3.js for rendering SVG. The chart combines area, line, and bar series, and colors volume bars red or green based on price movement. Data is loaded from `yahoo.csv` and parsed from timestamps into dates.

Yahoo Finance Chart Step 11 - Intraday Data

A Yahoo Finance intraday stock chart displays open, high, low, close, and volume data as an area-plus-line series with a red exponential moving average line. The visualization uses the D3FC library with D3.js to render SVG elements, including annotations for the last close and EMA values, a legend, and a crosshair. Data comes from a local JSON file containing Yahoo Finance chart data, filtered to trading hours and formatted with time and price scales.

Yahoo Finance Chart Step 2 - Gidlines and Area

This example shows a financial time series chart of Yahoo stock prices, plotting open values as both a filled area and an overlaid line against timestamps. The chart uses horizontal gridlines for scale reference, with five y-axis ticks and a cleaned domain for readability. Built with D3 and the d3fc library, the code constructs a `linearTimeSeries` chart, composes area, line, and gridline series via `fc.series.multi`, and renders the result as an SVG. Data is loaded from a CSV file.
