androidplot line not displayed - line

Question

I'm expecting to see a straight line defined by 2 points on my graph but nothing shows up.
I followed the tutorial and everything worked fine, then I tried to change the series of numbers. Here is the code:
plotList is of type List and it contains 2 values 12.634 and 12.634
XYSeries series1 = new SimpleXYSeries(plotList,
SimpleXYSeries.ArrayFormat.Y_VALS_ONLY,
"Series1");
// Create a formatter to use for drawing a series using
// LineAndPointRenderer
// and configure it from xml:
LineAndPointFormatter series1Format = new LineAndPointFormatter();
series1Format.setPointLabelFormatter(new PointLabelFormatter());
series1Format.configure(parentActivity.getApplicationContext(),
R.xml.line_point_formatter_with_plf1);
//plot.setDomainRightMax(plotList.size());
//plot.setDomainBoundaries(0, 5, BoundaryMode.AUTO);
// plot.setDomainStepValue(1);
//plot.setRangeBoundaries(0,40,BoundaryMode.AUTO);
// add a new series' to the xyplot:
plot.addSeries(series1, series1Format);
// reduce the number of range labels
plot.setTicksPerRangeLabel(3);
plot.getGraphWidget().setDomainLabelOrientation(-45);

Answer 1

Try this
List<Number> plotList = new ArrayList<Number>();
plotList.add(1212);
plotList.add(12334);
XYSeries series1 = new SimpleXYSeries(plotList,SimpleXYSeries.ArrayFormat.Y_VALS_ONLY, "Series1");
LineAndPointFormatter series1Format = new LineAndPointFormatter(
Color.rgb(0, 200, 0), // line color
Color.rgb(0, 100, 0), // point color
Color.rgb(150, 190, 150)); // fill color (optional)
XYPlot plot = (XYPlot) findViewById(R.id.mySimpleXYPlot);;
plot.addSeries(series1, series1Format);
// reduce the number of range labels
plot.setTicksPerRangeLabel(3);
// plot.getGraphWidget().setDomainLabelOrientation(-45);
and ur xml should be
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<com.androidplot.xy.XYPlot
android:id="#+id/mySimpleXYPlot"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
title="Stats" />
</LinearLayout>
