Design of dynamic line chart component based on Android
The components provided by the Android system cannot fully meet the needs of developers,and many components need to be implemented by rewriting the View.In terms of data visualization,dynamic line graphs are a commonly used component that displays information in real-time based on the continuous changes of data.Based on this issue,a design and implementation method for dynamic line graphs is proposed,and key technologies such as data models,timers,line smoothing,and component draw-ing are discussed in detail.The component design is reasonable,easy to use,supports customization,and has good real-time perfor-mance.It can meet the needs of most Android application development and has certain practical application value and innovation.
