    <p>Hii i am displaying 4 values in a bargraph where each bar is different color.when i am displaying the graph each bar overlapping each other.i want to make space between the bars i tried with <code>setBarSpacing()</code> by putting different values still its not working.is there any other idea.</p> <pre><code>package com.example.barchartview; import org.achartengine.ChartFactory; import org.achartengine.GraphicalView; 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.os.Bundle; import android.annotation.SuppressLint; import android.app.Activity; import android.graphics.Color; import android.view.View; import android.widget.LinearLayout; @SuppressLint("ParserError") public class MainActivity extends Activity { private GraphicalView BarChartView; @SuppressLint("ParserError") @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); if (BarChartView==null ) { XYMultipleSeriesRenderer renderer = buildBarRenderer(); setChartSettings(renderer); BarChartView = ChartFactory.getBarChartView(this, getBarDataset(), renderer, Type.DEFAULT); LinearLayout playout = (LinearLayout) findViewById(R.id.graph2); playout.addView(BarChartView); ; } else { BarChartView.repaint(); BarChartView.setVisibility(View.GONE); } } private void setChartSettings(XYMultipleSeriesRenderer renderer) { renderer.setYTitle("Hits"); renderer.setXAxisMin(0); renderer.setXAxisMax(7); renderer.setYAxisMin(0); renderer.setYAxisMax(900); } private XYMultipleSeriesDataset getBarDataset() { int[] y = {624,430,712,323}; CategorySeries series1 = new CategorySeries("A"); CategorySeries series2 = new CategorySeries("B"); CategorySeries series3 = new CategorySeries("C"); CategorySeries series4 = new CategorySeries("D"); XYMultipleSeriesDataset dataset = new XYMultipleSeriesDataset(); series1.add(y[0]); dataset.addSeries(series1.toXYSeries()); series2.add(y[1]); dataset.addSeries(series2.toXYSeries()); series3.add(y[2]); dataset.addSeries(series3.toXYSeries()); series4.add(y[3]); dataset.addSeries(series4.toXYSeries()); return dataset; } protected XYMultipleSeriesRenderer buildBarRenderer() { XYMultipleSeriesRenderer mrenderer = new XYMultipleSeriesRenderer(); double[] range = {0,5,0,5}; mrenderer.setAxisTitleTextSize(16); mrenderer.setChartTitleTextSize(20); mrenderer.setLabelsTextSize(15); mrenderer.setLegendTextSize(15); mrenderer.setBarSpacing(0); mrenderer.setXLabels(1); mrenderer.addXTextLabel(2.5, ""); mrenderer.setMargins(new int[] {20, 30, 15, 0}); mrenderer.setAxesColor(Color.WHITE); mrenderer.setChartTitle(""); mrenderer.setXTitle(""); mrenderer.setInitialRange(range, 1); XYSeriesRenderer renderer1 = new XYSeriesRenderer(); renderer1.setColor(Color.GREEN); XYSeriesRenderer renderer2 = new XYSeriesRenderer(); renderer2.setColor(Color.RED); XYSeriesRenderer renderer3 = new XYSeriesRenderer(); renderer3.setColor(Color.BLUE); XYSeriesRenderer renderer4 = new XYSeriesRenderer(); renderer4.setColor(Color.CYAN); mrenderer.addSeriesRenderer(renderer1); mrenderer.addSeriesRenderer(renderer2); mrenderer.addSeriesRenderer(renderer3); mrenderer.addSeriesRenderer(renderer4); return mrenderer; } } </code></pre> <p>here is my code.</p> <p>here is my activity_main.xml file</p> <pre><code>&lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/mainActivity" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" &gt; &lt;LinearLayout android:id="@+id/graph2" android:layout_width="160dip" android:layout_height="200dip" android:scaleType="fitEnd" android:layout_marginTop="40dip" android:layout_marginLeft="790dip"/&gt; &lt;/RelativeLayout&gt; </code></pre>

    1. COHmm, changing `setBarSpacing()` makes a noticeable difference in the demo app, specifically `SalesStackedBarChart.java`. Post your code so we can see what's wrong.

    3. COYou are calling a lot of methods twice, including `setBarSpacing()`. Which `setBarSpacing()` were you altering the first or the second? (You should remove the duplicate calls since they do nothing.)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
