Unable to show graphs in android (2 answers)

Closed 9 years ago.

I'm trying to use the aChart engine library for an android app. this is the activity i'm trying to run with an onClick event.

package com.example.euroxxi_testeficheiro;


import org.achartengine.ChartFactory;
import org.achartengine.chart.BarChart.Type;
import org.achartengine.model.CategorySeries;
import org.achartengine.model.XYMultipleSeriesDataset;
import org.achartengine.renderer.XYMultipleSeriesRenderer;
import org.achartengine.renderer.XYSeriesRenderer;

import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.graphics.Color;

public class ChartTeste extends Activity{

    public Intent getIntent(Context context) 
    {   
        // Bar 1
        int[] y = { 124, 135, 443, 456, 234, 123, 342, 134, 123, 643, 234, 274 };
        CategorySeries series = new CategorySeries("Demo Bar Graph 1");
        for (int i = 0; i < y.length; i++) {
            series.add("Bar " + (i+1), y[i]);
        }

        // Bar 2
        int[] y2 = { 224, 235, 243, 256, 234, 223, 242, 234, 223, 243, 234, 274 };
        CategorySeries series2 = new CategorySeries("Demo Bar Graph 2");
        for (int i = 0; i < y.length; i++) {
            series2.add("Bar " + (i+1), y2[i]);
        }

        XYMultipleSeriesDataset dataset = new XYMultipleSeriesDataset();
        dataset.addSeries(series.toXYSeries());
        dataset.addSeries(series2.toXYSeries());

        // This is how the "Graph" itself will look like
        XYMultipleSeriesRenderer mRenderer = new XYMultipleSeriesRenderer();
        mRenderer.setChartTitle("Demo Graph Title");
        mRenderer.setXTitle("X VALUES");
        mRenderer.setYTitle("Y VALUES");
        mRenderer.setAxesColor(Color.GREEN);
        mRenderer.setLabelsColor(Color.RED);
        // Customize bar 1
        XYSeriesRenderer renderer = new XYSeriesRenderer();
        renderer.setDisplayChartValues(true);
        renderer.setChartValuesSpacing((float) 0.5);
        mRenderer.addSeriesRenderer(renderer);
        // Customize bar 2
        XYSeriesRenderer renderer2 = new XYSeriesRenderer();
        renderer.setColor(Color.CYAN);
        renderer.setDisplayChartValues(true);
        renderer.setChartValuesSpacing((float) 0.5);
        mRenderer.addSeriesRenderer(renderer2);

        Intent intent = ChartFactory.getBarChartIntent(context, dataset,mRenderer, Type.DEFAULT);
        return intent;
    }

}
