I am trying to create a line graph with six lines, and two Y

  • 0

I am trying to create a line graph with six lines, and two Y Axis. All six lines will use the same X-axis, but 3 lines should be graphed with respect to one Y-axis, and the other 3 lines graphed with respect to the other Y-axis.

I have been looking at this tutorial but cannot quite figure out whats going on.

Does this line represent creating a chart with 2 lines to be graphed, or a chart with 2 y-axis?

XYMultipleSeriesRenderer renderer = new XYMultipleSeriesRenderer(2);

The JavaDocs do not explain the parameter at all. It simply says scaleNumber, which is explained nowhere.

Also, is there anyway to work with AChartEngine without using Intents? I currently have everything set up to create the graph and just set a LinearLayout to display it. There are other things on the page other than the graph.

    In short, yes, scaleNumber refers to the number of Y scales that you have in your chart. When another method call refers to scaleNumber, it is normally to clarify which scale to apply the method to.

    Also, is there anyway to work with AChartEngine without using Intents? I currently have everything set up to create the graph and just set a LinearLayout to display it. There are other things on the page other than the graph.

    Again, yes. I use it in my applications like this:

    GraphicalView graph = ChartFactory.getTimeChartView(myContext, data, renderer, xLabelFormat);
    
LinearLayout myLL = (LinearLayout) findViewById(R.id.graph_container);
myLL.addView(graph);

    All of the chart types can be retrieved as either Intents or Views (full list in the Javadoc here: http://www.achartengine.org/content/javadoc/org/achartengine/ChartFactory.html)
