Java – androidplot – delete field values from graphwidget

I have such a plot setting:

aHistoryPlot = (XYPlot) findViewById(R.id.plot);
    aHistoryPlot.setRangeBoundaries(0, 255, BoundaryMode.FIXED);
    aHistoryPlot.setDomainBoundaries(0, HISTORY_SIZE, BoundaryMode.FIXED);
    aHistoryPlot.addSeries(YHistorySeries, new LineAndPointFormatter(Color.rgb(100, 200, 100), Color.TRANSPARENT, null));
    aHistoryPlot.getGraphWidget().setMarginTop(10);
    aHistoryPlot.setDomainStepValue(5);
    aHistoryPlot.setTicksPerRangeLabel(3);
    aHistoryPlot.setDomainLabel(getResources().getString(R.string.string_time));
    aHistoryPlot.getDomainLabelWidget().pack();
    aHistoryPlot.setRangeLabel(getResources().getString(R.string.string_value));
    aHistoryPlot.getRangeLabelWidget().pack();
    aHistoryPlot.disableAllMarkup();

How do I delete a field value from a graph?

Thank you in advance!

resolvent:

You can enter:

aHistoryPlot.getGraphWidget().getDomainLabelPaint.setColor(Color.TRANSPARENT);
