// iOS Vital Signs ECG/EKG Medical Demo
SciChart® the market leader in Fast WPF Charts, WPF 3D Charts, and iOS Chart & Android Chart Components
iOS Vital Signs ECG/EKG Medical Demo
// iOS Chart Examples
Please note! These examples are new to SciChart iOS v3 release! SciChart’s OpenGLES and Metal iOS Chart library ships with ~90 Objective-C and Swift iOS Chart Examples which you can browse, play with and view the source-code. All of this is possible with the new and improved SciChart iOS Examples Suite, which ships as part of the SciChart iOS SDK.
The Vital Signs demo showcases how to use SciChart iOS Charts in a medical context.
Four channels of data are simulated, showing how SciChart iOS 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 Ventilators, patient monitors, digital stethoscopes 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 Chart library.
// Source Code
The Swift and Objective-C source code for the iOS Multiple Axis Demo example is included below (Scroll down!).
Did you know that we have the source code for all our example available for free on Github?
Clone the SciChart.iOS.Examples from Github.
Also the SciChart iOS Trial contains the full source for the examples (link below).
The SciChart Examples source code is available on Github and viewable in-app for some platforms
