achartengine

Can u please help me in creating a simple bar chart (for android) where the values are got from sqlite database. for eg consider the following table year Units Sold 2001 2000 2002 2100 2003 1900 I need to create a bar graph with x-axis as year and y-axis as units sold . Can u Plz consider this as a request . I dont know how to import data from database . first you have to fetch the values from the data base and stored into array with corresponding data type . Do like this..... List<int[]> initial; int[] my_year; int[] my_units_sold; public void onCreate() { int Column1 = net_db_cur

I'm using achartEngine library ,and i'm drawing a bar graphe .I would like to have a superposable bars for example if they have the same X coordinates. This is what i wont to obtaine : This is what i'm actualy obtaining : If two bars hve the same x ,they are just neighbors.And this is not clear to undertand and specialy if i have more then two bars with the same x. And this is the code i'm using : public class TruitonAChartEngineActivity extends ActionBarActivity { private static int SERIES_NR ; //the number of columns to display, List<int[]> values = new ArrayList<int[]>(); @Override

everywhere i look, the only information I can find says to add them via the following code series.addAnnotation("Hello!!", 1, 1); However, When I try it in my code (with the proper series name) I get an error message that says addAnnotation is not supported. Can someone please clear this up for me? thanks! You must download a recent version of the library. For example, get the night build from here . In your code, replace the last line (the one where you return the chart view) with: XYMultipleSeriesDataset dataset = buildBarDataset(titles, values); XYSeries series = dataset.getSeriesAt(0);
