Remove a lengend from an XYPlot

Question

Am using AndroidPlot on my project and it's just great so far. This is what i got.

Now am trying to remove one of the series indicators from the legend. Actually i want to keep only the first one (the blue one) cause the others are self explanatory.

Am not asking how to remove the legend it self (see https://stackoverflow.com/a/13413758/665823 for that issue).

If someone can help me i'll be great. Thanks in advance.

Answer 1

I finally found a tweek that allows me to do what i need. To achieve this the series that i need to be shown must be added to the plot first over the ones i need to hide :

// I add the blue serie first
LineAndPointFormatter mFormat = new LineAndPointFormatter();
mFormat.configure(context, R.xml.plot_blue);
graphView.addSeries(serieMesures, mFormat);

// I add the other colors after
for (XYSeries serie : seriesSeuils) {
     LineAndPointFormatter sFormat = new LineAndPointFormatter();
     if (serie.getTitle().equals("RED") {
        sFormat.configure(context, R.xml.plot_red);
     } 
     else if (serie.getTitle().equals("ORANGE")) {
        sFormat.configure(context, R.xml.plot_orange);
     }
     else if (serie.getTitle().equals("YELLOW")) {
        sFormat.configure(context, R.xml.plot_yellow);
     }
     graphView.addSeries(serie, sFormat);
}

Then i just created a legend where there is only enough space to show the series i need (in my case just the first one).

// This is what does the trick! A Table with 1 line and 1 column 
// so the other series can't be rendered in the LegendWidget
graphView.getLegendWidget().setTableModel(new DynamicTableModel(1, 1));

// Other customizations (size and position)
graphView.getLegendWidget().setSize(new SizeMetrics(55, SizeLayoutType.ABSOLUTE, legendWith, SizeLayoutType.ABSOLUTE));
graphView.getLegendWidget().setPositionMetrics(
     new PositionMetrics(20,
                         XLayoutStyle.ABSOLUTE_FROM_RIGHT,
                         20,
                         YLayoutStyle.ABSOLUTE_FROM_TOP,
                         AnchorPosition.RIGHT_TOP));
graphView.getLegendWidget().setBackgroundPaint(bgPaint);
graphView.getLegendWidget().setTextPaint(txPaint);
graphView.getLegendWidget().setBorderPaint(brPaint);
graphView.getLegendWidget().setPadding(10, 1, 10, 1);

And voila!
