Performance & Scalability

icon

Can SciChart handle real-time updates at 60 FPS or more?

Yes. SciChart’s high-performance graphics engine can comfortably handle data rendering at 60 FPS, or even more!
icon

How many data points can I realistically render?

Over the years, we have vastly improved our data rendering performance. With our WPF chart library, you can achieve 1-billion data points with sorted data and around 10,000,000 points with unsorted data. With our JavaScript chart library, you can load 1-million data points in under 15 milliseconds.
icon

Should I be using SVG, Canvas, or WebGL for large data sets?

SVG based JavaScript chart libraries are good when you’re rendering less data but very flexible for styling. Canvas 2D charts are faster but get quite slow as they reach 10,000 datapoints. WebGL based chart libraries offer the fastest approach to data rendering using hardware acceleration. If you want to render over 100,000 data points you will need to use WebGL.
icon

Is there a charting library that can handle 100k+ points without lag?

Yes! You may have tried other libraries in the past and struggled to get past the 100,000 data mark without experiencing lag or freezing UIs. However, with SciChart’s accelerated graphics engine, this isn’t a problem! Check out our one million data points demo.
icon

What optimizations does SciChart use?

SciChart uses WebGL and data resampling which downsizes the data points. Redraw throttling also occurs automatically. Check out this documentation on sub-charts for SciChart.js.
icon

How well does SciChart handle multiple charts on a single dashboard?

SciChart supports multiple charts on one page with optimal performance of the data. We have tutorials for each of the platforms, languages and frameworks to show you how to link multiple charts and build dashboards. Check out this documentation on sub-charts for SciChart.js.
icon

Can SciChart maintain smooth zooming and panning with large data sets?

Yes—one of the many performance benefits of using SciChart includes that you can maintain smooth zooming and panning even with large data sets thanks to the resampling algorithms.
icon

How do I prevent frame drops or UI freezing with real-time updates?

Preventing frame drops or UI freezing depends on the project. We have different options for performance optimization depending on the problem, and we can find the one that fits best for your particular case. As a performance troubleshooting starting point, we recommend referring to our Performance Tips documentation. Our developer team is also on hand to help.

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.
