I’m currently developing an Android application which needs to receive data from a bluetooth device, and then display it. Some of this data comes in the form of sin/cos waves, and needs to be graphed.
Does anyone know how to add graphs to my Activity? The graph should be blank initially, then the user can choose from 12 different signals to graph.
Thank you
achartengine is a graphing library that was built for android.
Google also provides the Image Charts API that will generate png’s for you which you can then show in an ImageView
I think both are capable of making line graphs. You’d just have to generate the data that will represent a sin/cos wave and pass it in to the chart engine.
