SciChart® the market leader in Fast WPF Charts, WPF 3D Charts, iOS Chart, Android Chart and JavaScript Chart Components

In these unprecedented and unusual times we are pleased to announce to you that we are not only still operational, but also delivering new features & updates to our users and today have a release of SciChart Mobile SDK v3.1!

This release brings you some long-standing features requested by our users via the Feature Request portal, and some showcase demos of how to use SciChart iOS, Android or Xamarin in medical or scientific context.

What’s New?

A full list of what’s new can be found below.

iOS/Android Vital Signs ECG/EKG demo

Formerly part of the SciChart showcase, we have created and updated our Vital Signs (ECG/EKG) demo showing how to use SciChart’s iOS, Android or Xamarin charts in a medical context.

Four channels of data are simulated, showing how SciChart iOS/Android can be used to draw real-time, high performance ECG/EKG charts & graphs to monitor blood pressure, SPO2 blood oxygen, and volumetric flow enabling you to create medical apps using an iPad or iPhone device.

SciChart helps you shortcut development of medical applications by providing rich, real-time, high performance & reliable iOS charts for use in Vital-signs monitors, blood pressure monitors, Electro-Cardiogram, medical Ventillators, patient monitors, digital stethoscopes, medical testing devices and more.

If you are creating an app that needs to visualize body temperature, pulse rate, respiration rate, blood pressure, or similar, choose SciChart to shortcut your development time & get to market faster with our well-tested, reliable
iOS/Android/Xamarin Chart library.

To view the Vital Signs demo, download the SciChart Examples from the /downloads page and go to Featured Apps -> Vital Signs Demo. Or, see the following links:

iOS/Android Audio, Radio Frequency & Spectrum Analyzer demo

Another demo we’ve created is the Audio/Radio Frequency Spectrum Analyzer demo.

The Audio analyzer demo showcases how to use SciChart iOS (android) charts in a scientific context. Download the examples and enable your microphone to see this demo at work.

Fast, real-time Audio / Radio Frequency Spectrum Analyzer demo now been added natively to SciChart’s iOS/Android/Xamarin Chart examples

In this example we listen to the microphone on your iOS/Android device and create a waveform of the sound recorded in the top chart. This chart has 500,000 data-points drawn in real-time on our High Performance charts. The example application then performs a Fourier Transform, creating a spectral / frequency analysis of the audio waveform and plots in the lower left chart. Finally, the histogram of the fourier transform, known as a spectrogram, is plotted in a SciChart iOS Heatmap control in the bottom right of the example.

If you are creating an app that needs to visualize scientific data from data-aquisition devices, audio spectra, or visualize radio frequency or spectrial analysis choose SciChart to shortcut your development time & get to market faster with our well-tested, reliable iOS/Android Chart library.

iOS/Android Spline Line Series

SciChart iOS & Android now features a native spline-line (smoothed line) series. Given a few number of points, our customers wanted to see smoother charts out of the box with spline smoothing / bezier interpolation between data-points.

SciChart Mobile SDK v3.1 features a spline line series which provides aesthetically pleasing, high performance smoothed line charts for iOS or Android apps.

Performance is excellent thanks to our intelligent, dynamic smoothing, and interactive frame rates with point counts in the 100,000 or even millions of data-points are still possible.

Fast, real-time Smoothed Line/ Spline Line charts have now been added natively to SciChart’s iOS/Android/Xamarin Chart library

To view the Spline Line Series, download the SciChart Examples from the /downloads page and go to 2D Charts -> Spline Line Series. Or, see the following links:

iOS/Android Spline Mountain Series

SciChart Mobile SDK v3.1 now features a spline mountain or area series which provides aesthetically pleasing, high performance smoothed mountain/area charts for iOS or Android apps.

Again, performance is excellent thanks to our dynamic smoothing and this chart type allows interactive frame-rates into the hundreds of thousands of points.

Fast, real-time Smoothed Mountain / Spline Mountain/Area charts have now been added natively to SciChart’s iOS/Android/Xamarin Chart library

To view the Spline Mountain Series, download the SciChart Examples from the /downloads page and go to 2D Charts -> Spline Mountain Series. Or, see the following links:

iOS/Android Spline Band Series

We’ve also added a spline band series natively which provides aesthetically pleasing, high performance smoothed band / high-low fill charts for iOS or Android apps.

Fast, real-time Smoothed Band / Spline Band charts have now been added natively to SciChart’s iOS/Android/Xamarin Chart library

To view the Spline Band Series, download the SciChart Examples from the /downloads page and go to 2D Charts -> Spline Band Series. Or, see the following links:

New Rounded-Column Custom Series Example

Column charts with rounded top/bottom have been requested via our Feature-request system. We haven’t build this feature natively but what we’ve done is used it as an example to showcase our powerful Custom Series API, which allows you to create any series type using a fast drawing context.

As we now support Spline Lines natively, we have adjusted our Custom Series demo to show you how to create a Rounded-Column series on iOS and Android. Find out how in the SciChart iOS/Android Examples App.

To view the Rounded-Column Custom Series Demo, download the SciChart Examples from the /downloads page and go to 2D Charts -> Custom Renderable Series. Or, see the following links:
