In a React app, opening and sharing data with a new (non-modal) window might seem like a challenge, but it's possible - and I've provided a component to make it even simpler.
In this article I'm going to create an interactive Fibonacci fan D3 component, and show you how to add it to a chart in just 6 lines of code.
In my last article I put together an interactive chart that could be panned and zoomed, but there was one obvious omission - crosshairs. In this article I'm going to create a D3 crosshairs component, and show you how to add it to a chart.
Recently I've been looking at various D3 components, which has been a fun project. I haven't yet had the chance to develop an interactive, dynamic component though, which has meant that the resulting charts have been sadly static. For this article I wanted to use what I've learned to build a fully interactive chart - something that wouldn't look out of place on a financial app.
In my last article (on line annotation components for D3 charts), I created a D3 component which calculated and displayed a moving average. As promised, I'm now turning my attention to Bollinger Bands.
In this article I'm going to create two simple, reusable D3 components for adding line annotations to charts.
