The flexibility of ChartIQ plus D3.js
At ChartIQ, we take users to the next level with charts that defy their expectations. Our HTML5 charting library is world-renowned for its stellar performance, customization, and easy deployment. You’ll find our charts on millions of desktops around the world (check out Yahoo! Finance, for example).
ChartIQ has historically been based on charting high-velocity financial data. Time series charting is our speciality, and yet the need to have other types of visualizations co-existing with ChartIQ has become apparent as we cater to different client use cases. To solve for this, we undertook an effort to incorporate D3.js into the ChartIQ ecosystem in order to leverage its unique data visualizations.
By creating a bridge between ChartIQ and D3.js, it’s possible to utilize the same dataset between multiple visualizations, resulting in a superior experience than implementing two completely separate visualizations.
Consider this sample use case for an active trader. You want to view a money flow pie chart as you’re viewing your financial data and order book. This way you can see up, down, and even at-a-glance. A money flow pie chart isn’t a time-series graph like ChartIQ typically draws, so how can we accommodate this use case?
The “active trader” template of ChartIQ uses a pie chart to demonstrate money flow:
Our pie chart is there in the lower-left corner, synched with our data. So how is this possible?
By leveraging the exact same data feed already present in memory, our D3 implementation doesn’t require additional API calls—that’s all given to you by your ChartIQ quote feed or web sockets integration. The wiring between the exact instance of the chart and the D3 instance(s) provides a single source of truth for the data, with each datum able to be represented in the D3 visualizations.

We have the capability, and the rest can be up to your needs and imagination.
What is provided out-of-the-box?
ChartIQ includes wrappers for piecharts, as well as methods for creating your own wrappers for any other D3.js rendering of your choice. Within the wrappers, the data ingestion methods, node transformations, scaling methods, and the other features of D3 are fully available. More built-in wrappers will be made available in upcoming releases to continue to grow “out of the box” D3 functionality.
ChartIQ’s customization is state-of-the-art and we welcome suggestions for how we can meet the needs of our clients.
