achartengine

问题 I am trying to add two dynamic line charts in vertical using AChartEngine. However I am getting some problem with the layout. Added below are the related java files, xml file and logcat(I have other java files like Ubidots.java , Point.java and Context.java but I don't think these are required here). LineGraph.java: public class LineGraph { private GraphicalView view; private TimeSeries dataset = new TimeSeries("LDR Values"); private XYMultipleSeriesDataset mDataset = new

问题 I am using AChartEngine to plot values obtained from Ubidots in real-time. The graph is retrieving values in real-time however when no value is being sent on Ubidots, the last retrieved value sent on Ubidots is being plotted again as shown in the screenshot. Here are my codes: LineGraph.java: public class LineGraph { private GraphicalView view; private TimeSeries dataset = new TimeSeries("LDR Values"); private XYMultipleSeriesDataset mDataset = new XYMultipleSeriesDataset(); private

问题 How can I create a Time Chart with multiple Y scales and axis with AChartEngine? Thanks 回答1: You will have to build a CombinedXYChart of line charts and use custom labels instead of the default ones. TimeChart is not supported in the CombinedXYChart . Update : See this example and just create a time chart instead of a cubic line chart. 来源： https://stackoverflow.com/questions/15623752/achartengine-time-chart-with-multiple-y-scales-and-axis
