SciChart® the market leader in Fast WPF Charts, WPF 3D Charts, iOS Chart, Android Chart and JavaScript Chart Components
Please note! These examples are new to SciChart iOS v4 release! SciChart’s OpenGL ES and Metal iOS and Metal macOS Chart library ships with hundred of Objective-C and Swift iOS&macOS 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 and demo application for Mac, which ships as part of the SciChart SDK.
SciChart iOS 3D supports selection of a data point. This example demonstrates selection functionality on the Scatter Point 3D Chart.
How to use example!To select a scatter point, please tap on one. Tapping on several points will allow you to select multiple points. To deselect, please tap on the already selected point again or long press on an empty place.
The selection functionality of points in 3D iOS graphs in SciChart is provided by SCIVertexSelectionModifier3D Modifier.
Please read more about selection and SCIVertexSelectionModifier3D in iOS SWIF and iOS Objective-C Charts with SciChart Component in our documentation.
The Swift and Objective-C source code for the iOS and macOS Select Scatter Point 3D Chart 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 and Scichart macOS Trials contain the full source for the examples (link below).
