Android GraphView

Question

I'm trying to use the GraphView but I can't seem to have labels :/

This is my GraphView:

// init example series data
GraphViewSeries exampleSeries = new GraphViewSeries(new GraphViewData[] {
    new GraphViewData(1, 2.0d)
    , new GraphViewData(2, 1.5d)
    , new GraphViewData(3, 2.5d)
    , new GraphViewData(4, 1.0d)
});
 
GraphView graphView = new LineGraphView(this , "GraphViewDemo");
graphView.setHorizontalLabels(new String[] {"2 days ago", "yesterday", "today", "tomorrow"});
graphView.setVerticalLabels(new String[] {"high", "middle", "low"});
graphView.addSeries(exampleSeries);
 
LinearLayout layout = (LinearLayout) findViewById(R.id.layout);
layout.addView(graphView);

And this is my xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" android:id="@+id/layout"
    android:orientation="vertical">
</LinearLayout>

This is what I get:

Big Edit!

Now the labels appear but they are too large, how can I reduce the font letter as well as the display overall ?

Answer 1

The problem might be with your text being white color. Just try

graphView.getGraphViewStyle().setHorizontalLabelsColor(Color.BLACK); graphView.getGraphViewStyle().setVerticalLabelsColor(Color.BLACK);

The size of text could be altered as follows... graphView.getGraphViewStyle().setTextSize(11);
