Androidplot - background and ranges

I'm new to that library. I'm trying to Create the following plot:

enter image description here

Meanwhile I have the next one:

enter image description here

My questions: NOTE: The colors doesn't matters

  1. How do I get rid of the black area (where was lables on range domain and title) and center the plot (like in the first picture)

  2. How to add ranges as in the first picture ? (x:[1-7] y:[0-4500])

  3. Make the same grid as in the first picture

My code:

public class MainActivity extends Activity {

private XYPlot mySimpleXYPlot;

@Override
public void onCreate(Bundle savedInstanceState)
{

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

 // Create a couple arrays of y-values to plot:
    Number[] days =   { 1  , 2   , 3   , 4   , 5   , 6   , 7 };
    Number[] values = { 380, 1433, 1965, 3200, 3651, 3215, 3217 };

    // initialize our XYPlot reference:
    mySimpleXYPlot = (XYPlot) findViewById(R.id.mySimpleXYPlot);
    mySimpleXYPlot.getBackgroundPaint().setColor(Color.WHITE);
    mySimpleXYPlot.setBorderStyle(XYPlot.BorderStyle.NONE, null, null);
    mySimpleXYPlot.getGraphWidget().getBackgroundPaint().setColor(Color.WHITE);
    mySimpleXYPlot.getGraphWidget().getGridBackgroundPaint().setColor(Color.WHITE);



    // Domain
    mySimpleXYPlot.getGraphWidget().setDomainLabelPaint(null);
    mySimpleXYPlot.getGraphWidget().setDomainOriginLinePaint(null);
    mySimpleXYPlot.setDomainStep(XYStepMode.INCREMENT_BY_VAL, days.length);     
    mySimpleXYPlot.setDomainValueFormat(new DecimalFormat("0"));


    //Range
    mySimpleXYPlot.getGraphWidget().setRangeOriginLinePaint(null);
    mySimpleXYPlot.setRangeStep(XYStepMode.SUBDIVIDE, values.length);
    mySimpleXYPlot.setRangeValueFormat(new DecimalFormat("0"));


    //Remove legend
    mySimpleXYPlot.getLayoutManager().remove(mySimpleXYPlot.getLegendWidget());
    mySimpleXYPlot.getLayoutManager().remove(mySimpleXYPlot.getDomainLabelWidget());
    mySimpleXYPlot.getLayoutManager().remove(mySimpleXYPlot.getRangeLabelWidget());
    mySimpleXYPlot.getLayoutManager().remove(mySimpleXYPlot.getTitleWidget());

    // Turn the above arrays into XYSeries':
    XYSeries series1 = new SimpleXYSeries(
            Arrays.asList(days),          
            Arrays.asList(values), 
            "Series1");                             // Set the display title of the series

    // Create a formatter to use for drawing a series using LineAndPointRenderer:
    LineAndPointFormatter series1Format = new LineAndPointFormatter(
            Color.rgb(0, 200, 0),                   // line color
            Color.rgb(0, 100, 0),                   // point color
            Color.CYAN);                            // fill color 

 // setup our line fill paint to be a slightly transparent gradient:
    Paint lineFill = new Paint();
    lineFill.setAlpha(200);
    lineFill.setShader(new LinearGradient(0, 0, 0, 250, Color.WHITE, Color.GREEN, Shader.TileMode.MIRROR));

    series1Format.setFillPaint(lineFill);

    // add a new series' to the xyplot:
    mySimpleXYPlot.addSeries(series1, series1Format);

    // by default, AndroidPlot displays developer guides to aid in laying out your plot.
    // To get rid of them call disableAllMarkup():
    mySimpleXYPlot.disableAllMarkup();
}

}

I hope this is helpful.

My code:

private XYPlot mySimpleXYPlot;

@Override
public void onCreate(Bundle savedInstanceState)
{

    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    // Create a couple arrays of y-values to plot:
    Number[] days =   { 1  , 2   , 3   , 4   , 5   , 6   , 7 };
    Number[] values = { 380, 1433, 1965, 3200, 3651, 3215, 3217 };

    // initialize our XYPlot reference:
    mySimpleXYPlot = (XYPlot) findViewById(R.id.mySimpleXYPlot);

    mySimpleXYPlot.setBorderStyle(Plot.BorderStyle.NONE, null, null);
    mySimpleXYPlot.setPlotMargins(0, 0, 0, 0);
    mySimpleXYPlot.setPlotPadding(0, 0, 0, 0);
    mySimpleXYPlot.setGridPadding(0, 10, 5, 0);

    mySimpleXYPlot.setBackgroundColor(Color.WHITE);

    mySimpleXYPlot.position(
            mySimpleXYPlot.getGraphWidget(),
            0,
            XLayoutStyle.ABSOLUTE_FROM_LEFT,
            0,
            YLayoutStyle.RELATIVE_TO_CENTER,
            AnchorPosition.LEFT_MIDDLE);

    mySimpleXYPlot.getGraphWidget().getBackgroundPaint().setColor(Color.WHITE);
    mySimpleXYPlot.getGraphWidget().getGridBackgroundPaint().setColor(Color.WHITE);

    mySimpleXYPlot.getGraphWidget().getDomainLabelPaint().setColor(Color.BLACK);
    mySimpleXYPlot.getGraphWidget().getRangeLabelPaint().setColor(Color.BLACK);

    mySimpleXYPlot.getGraphWidget().getDomainOriginLabelPaint().setColor(Color.BLACK);
    mySimpleXYPlot.getGraphWidget().getDomainOriginLinePaint().setColor(Color.BLACK);
    mySimpleXYPlot.getGraphWidget().getRangeOriginLinePaint().setColor(Color.BLACK);

    // Domain
    mySimpleXYPlot.setDomainStep(XYStepMode.INCREMENT_BY_VAL, days.length);     
    mySimpleXYPlot.setDomainValueFormat(new DecimalFormat("0"));
    mySimpleXYPlot.setDomainStepValue(1);

    //Range
    mySimpleXYPlot.setRangeBoundaries(0, 4500, BoundaryMode.FIXED);
    mySimpleXYPlot.setRangeStepValue(10);
    //mySimpleXYPlot.setRangeStep(XYStepMode.SUBDIVIDE, values.length);
    mySimpleXYPlot.setRangeValueFormat(new DecimalFormat("0"));

    //Remove legend
    mySimpleXYPlot.getLayoutManager().remove(mySimpleXYPlot.getLegendWidget());
    mySimpleXYPlot.getLayoutManager().remove(mySimpleXYPlot.getDomainLabelWidget());
    mySimpleXYPlot.getLayoutManager().remove(mySimpleXYPlot.getRangeLabelWidget());
    mySimpleXYPlot.getLayoutManager().remove(mySimpleXYPlot.getTitleWidget());

    // Turn the above arrays into XYSeries':
    XYSeries series1 = new SimpleXYSeries(
            Arrays.asList(days),          
            Arrays.asList(values), 
            "Series1");                             // Set the display title of the series

    // Create a formatter to use for drawing a series using LineAndPointRenderer:
    LineAndPointFormatter series1Format = new LineAndPointFormatter(
            Color.rgb(0, 200, 0),                   // line color
            Color.rgb(0, 100, 0),                   // point color
            Color.CYAN);                            // fill color 

 // setup our line fill paint to be a slightly transparent gradient:
    Paint lineFill = new Paint();
    lineFill.setAlpha(200);
    lineFill.setShader(new LinearGradient(0, 0, 0, 250, Color.WHITE, Color.GREEN, Shader.TileMode.MIRROR));

    series1Format.setFillPaint(lineFill);

    // add a new series' to the xyplot:
    mySimpleXYPlot.addSeries(series1, series1Format);

    // by default, AndroidPlot displays developer guides to aid in laying out your plot.
    // To get rid of them call disableAllMarkup():
    mySimpleXYPlot.disableAllMarkup();
}

}

It will look like this:
