achartengine

I am totally new to Android and i am trying to create a bar chart using AChartEngine, it has 3 bars and each bar should be different color. I tried using multiple series but can't make my x-axis values align with bars protected void onResume() { super.onResume(); layout = (LinearLayout) findViewById(R.id.chart); if (mChartView == null) { PeakSeries = new XYSeries("Income"); ForecastPeakSeries = new XYSeries("Expense"); ForecastSeries = new XYSeries("Expense"); int[] x = { 1,2,3}; int income = 2000; int expense = 2700; System.out.println("Here"); Series1.add(x[0],income); Series2.add(x[1]

I have a problem. I'm making a graph with AChartEngine and I would like to have the background of the whole graph to be transparent: XYMultipleSeriesRenderer renderer = new XYMultipleSeriesRenderer(); (...) renderer.setMargins(new int[]{0,0,0,0}); renderer.setApplyBackgroundColor(true); renderer.setMarginsColor(Color.TRANSPARENT); renderer.setBackgroundColor(Color.TRANSPARENT); (...) GraphicalView g = ChartFactory.getTimeChartView(this, dataset, renderer, "dd/MM"); But it isn't working properly: As you can see, there is a black box appearing behind the x-labels. What am I doing wrong? Thanks

I want to draw a bar chart which contains five individual bars - I have used Achartengine. I am able to display all five bars in the same color but I want to differentiate one bar with a different color, but I cant display more than one color. Please show me how to display different colors. My code... values.add(new double[] {21,56,33,10,20}); int[] colors = new int[] { Color.rgb(227, 121, 15) }; XYMultipleSeriesRenderer renderer = buildBarRenderer(colors); setChartSettings(renderer, "", "", "", 0,5, 0,100, Color.WHITE, Color.WHITE); renderer.setXLabels(8); renderer.setYLabels(10); renderer

I'm new in android and I want to use achartengine to implement time chart that represent the daily outgoing call durations from call log. Does any one know how can I do this and what should I do? toni So you need a layout (main.xml): <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" > <LinearLayout android:id="@+id/chart" android:layout_width="fill_parent" android:layout_height="wrap_content" android:orientation="horizontal" />

I am trying to find a fast and reliable charting library. After some searching, I found 4 libraries: AChartEngine , WilliamChart , HelloCharts and AndroidPlot . I need some up to date feedback about the performance and the stability of these libraries because all the information I could find was outdated. You can use MPAndroidChart . It's native, free, easy to use, fast and reliable. Core features , benefits: LineChart, BarChart (vertical, horizontal, stacked, grouped), PieChart, ScatterChart, CandleStickChart (for financial data), RadarChart (spider web chart), BubbleChart Combined Charts (e
