iOS & macOS Vertical Charts Example
// 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 a vertical iOS chart with XAxis on the Left, Right, and YAxes at the Top. SciChart iOS supports unlimited X and Y axis and allows placement of any axis on the Left, Right, Top, Bottom of the chart.
The Vertical Chart is created by setting XAxis.axisAlignment = SCIAxisAlignment_Left, and YAxis.axisAlignment = SCIAxisAlignment_Top
This type of chart is useful in the Oil & Gas industry, where iOS Charts might be used to visualize Drill Depth.
// Source Code
The Swift and Objective-C source code for the iOS and macOS Vertical Charts Example 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).
The SciChart Examples source code is available on Github and viewable in-app for some platforms
