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.
This example demonstrates how to add tooltips to a series on a SciChart iOS 3D Charts.
Read more about Tooltip Modifier in iOS 3D in SciChart documentation and tutorials about Cursor and Tooltips in 3D.
The Swift and Objective-C source code for the iOS and macOS Series Tooltips 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).
