Android chart Class Library: William chart,
William chart is an Android chart class library based on Views. It helps developers implement line charts, bar charts, and Stacked column charts in Android applications. When the value changes, the chart also changes with the animation effect.
At the moment it provides:
LineChartView
BarChartView
StackBarChartView
Instructions for use:To create a new chart, you must inherit the coordinate axes of the Ch
Preface: Today to share a very beautiful powerful chart library, I hope that the students who need help, like to please a praise, support. Thank you!How to join the Swift library in a project see my previous articleHttp://www.jianshu.com/p/fd91c10c9f55Compilation Environment: Xcode7.3Add Charts Chart Library// 在Podfile中‘Charts‘import ChartsCreate bar chartfunc createLineChartView() { chartView = BarChartView.init(frame: CGRectMake(06464))

The code below is from a function call to create my email message. in my app, I am taking a UIView (or at least, a class derived from UIView) and converting it into a PNG image. once I convert the view to PNG, I then convert the image data to a Base64 string, and use that Base64 string as the source for my embedded image in the email.
