iOS Dashed Line Chart
// iOS Chart Examples
SciChart’s 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.
This example demonstrates how to create a Dashed Line in an iOS Chart.
What we do is create a normal iOS Line Chart and apply dashed line styling. This is achieved in code by setting the strokeStyle property with a Stroke Dash.
// Source Code
The Swift 4 and Objective-C source code for the iOS Dashed Line 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).
