iOS & macOS charts - Examples
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 Charting Component ships with various 3D chart types. Those are complemented by a number of features out of the box, to make it serve your needs the best with as little customization on your side as possible.
This example demonstrates how to add contours meshes to the floor and ceiling of an iOS 3D Graph Axis Cube.
Read more about configuring SciChart iOS Chart 3D Contours and Wireframe on Surface Mesh.
The Swift and Objective-C source code for the iOS and macOS Surface Mesh 3D Floor and Ceiling 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).
