// iOS Chart Examples

SciChart’s OpenGLES iOS Chart library ships with ~60 Objective-C and Swift 4 iOS Chart Examples which you can browse, play with, view the source-code and even export each iOS Objective-C / Swift Chart Example to a stand-alone XCode project. All of this is possible with the new and improved SciChart iOS Examples Suite, which ships as part of the SciChart iOS SDK.

// iOS Stacked Column Chart

Generates a Stacked Column chart in code-behind. See Documentation on how to use this type here: The IOS Stacked Mountain Chart.

The SCIStackedColumnRenderableSeries API can be used to render columns stacked above each other, or side by side in either Swift or Objective C. Grouping is performed when you place multiple SCIStackedColumnRenderableSeries into a SCIVerticallyStackedMountainsCollection or for horizontal column groups, the SCIHorizontallyStackedColumnsCollection.

Data is provided by a DataSeries, e.g. the SCIXyDataSeries, XyyDataSeries (uses Y1 only) or SCIOhlcDataSeries (renders close).

Mountains are styled using the Stroke (outline) and Fill (fill).

// Source Code

The Swift 4 and Objective-C source code for the iOS Stacked Column Chart example is included below (Scroll down!).

Did you know you can also view the source code from one of the following sources as well?

Clone the SciChart.iOS.Examples from Github.
Or, view source and export each example to an XCode project from the Obj-C version of the SciChart iOS Examples app.
Also the SciChart iOS Trial contains the full source for the examples (link below).
