What JavaScript chart types are available?

We support over 30 WebGL 2D and 3D JavaScript chart types, including a JavaScript candlestick chart, heatmap, scatter chart, line chart, column chart and donut chart. In most cases, you’ll be able to create the chart type you require—especially as we offer many customizable properties. However, if there are any examples of charts that you’d like us to add to our examples library, feel free to reach out through our JavaScript forum.

How can we style tooltips on JavaScript charts?

We have various documentation that not only shows you the basics of how to add tooltips, but how to modify their behavior and style. As a starting point, we recommend viewing our CursorModifier Types, Tooltip Modifier for 3D Charts, RolloverModifier documentation and Formatting CursorModifier Tooltip items. Using the available properties, you can change the text color, stroke color and thickness and the background color of the tooltip container.

How do we create our own JavaScript chart modifiers?

With our ChartModifier API, you get complete flexibility over your chart creation. Building your own Interactions can be complex, and the API comes with a learning curve for beginners. However, learning Custom Chart Modifiers is worth it for the powerful results. Once you’ve mastered how to use it, it becomes easier each time you create an interaction from scratch. Check out our ChartModifier API for JavaScript to see how it works and get started.

Can we create accessible JavaScript charts with SciChart?

Yes. We have documentation to help you create accessible JavaScript charts, including keyboard accessibility, adding voice over to data series and axes, and adding color and contrast. Combined, these features support users who are color blind or hard of hearing and conform to standards outlined in the W3C Web Accessibility Initiative.

Do your JavaScript charts support touchscreen on mobile?

Yes! Our charts are intuitively designed to support the touchscreen functions on mobile devices. Our built-in pinch, zoom and pan interactions are ideal for smartphone users and all the data visualization features you see on desktop are compatible with mobile devices.

Without doubt, the best charting library I have ever used. The examples suite is comprehensive to easily get you started coding on a new project. The sales & technical support staff are always responsible and eager to help. Chart customisation is extensive and rendering speed is quick.

This is an incredible product. First it's the best chart I've had customers compliment how great the charting parts of our application look/behave. I couldn't recommend this product anymore than I already do. SciChart really hit the mark. I wish all software products could be this easy to use and be so productive (not to mention blazing fast).

This is a wonderful tool for developers who need highly customizable and fast charting in 2D or 3D. I did a comprehensive market research in terms of what kind of charting I have to use for a commercial app. I've come to the conclusion that SciChart is simply the best charting framework out there meeting our needs. Keep up the good and quality work!

We have been coding Technical Analysis software for 16 years and during that time have tried most charting modules on the market. SciChart is by far the best, not only for features, speed and reliability, but their support has been above and beyond anything else we’ve experienced.

SciChart is flexible and reliable, just the component we need. We try to tweak the look and feel of the graphs to some extremes, all made possible by SciChart. Support is fast, not just a standard reply but usually a useful answer within a day. For more complex requests they really work with you to get it working.
