Android的 - achartengine条形图问题 [英] Android - achartengine bar chart issues

问题描述

我用achartengine绘制图表我在Android应用程序，并有2个问题与条形图。

I use achartengine to draw my chart in an android application and have 2 issues with bar chart.

1：在顶栏值不居中对齐

1: values at top bar doesn't align center

2：巴宽度太小，当图只有1条

2: width of bar too small when just 1 bar in chart

下面我code设置图表

Here my code for setting chart

    GraphicalView mChart;
    // Creating an  XYSeries for Income
    XYSeries incomeSeries = new XYSeries("\n" + note);
    // Adding data to Series
    // Arraylist<String> althongtin include input data (some numbers character, eg: {125, 4356, 50000})
    for(int i=0;i<althongtin.size();i++){
        incomeSeries.add(i, Double.parseDouble(althongtin.get(i)));
    }

    // Creating a dataset to hold each series
    XYMultipleSeriesDataset dataset = new XYMultipleSeriesDataset();
    // Adding Income Series to the dataset
    dataset.addSeries(incomeSeries);
    XYSeriesRenderer incomeRenderer = new XYSeriesRenderer();

    incomeRenderer.setColor(color);
    incomeRenderer.setChartValuesTextSize(20);
    incomeRenderer.setFillPoints(true);
    incomeRenderer.setDisplayChartValues(true);
    incomeRenderer.setChartValuesTextAlign(Paint.Align.CENTER);

    XYMultipleSeriesRenderer multiRenderer = new XYMultipleSeriesRenderer();

    multiRenderer.setXLabels(0);
    multiRenderer.setChartTitle(ten);
    multiRenderer.setXTitle(cotx);
    multiRenderer.setYTitle(coty);
    multiRenderer.setYLabelsAlign(Paint.Align.LEFT);
    multiRenderer.setBarSpacing(1);
    multiRenderer.setBarWidth(50);

    multiRenderer.setYAxisMin(0);
    multiRenderer.setYAxisMax(max + (max/10));
    multiRenderer.setXAxisMin(-1);
    multiRenderer.setXAxisMax(althongtin.size() + 1);
    multiRenderer.setLabelsTextSize(15);
    multiRenderer.setLegendTextSize(20);
    multiRenderer.setAxisTitleTextSize(20);
    multiRenderer.setChartTitleTextSize(20);

    multiRenderer.setLabelsColor(Color.BLACK);
    multiRenderer.setAxesColor(Color.BLACK);
    multiRenderer.setApplyBackgroundColor(true);
    multiRenderer.setBackgroundColor(Color.TRANSPARENT);
    multiRenderer.setMarginsColor(Color.argb(0,255,255,255));
    multiRenderer.setXLabelsColor(Color.BLACK);
    multiRenderer.setYLabelsColor(0, Color.BLACK);

    multiRenderer.addSeriesRenderer(incomeRenderer);

    String[] types = new String[] {BarChart.TYPE};

    mChart = (GraphicalView) ChartFactory.getCombinedXYChartView(getBaseContext(), dataset, multiRenderer, types);

    multiRenderer.setClickEnabled(true);
    multiRenderer.setSelectableBuffer(10);

    chartLayout.addView(mChart);

感谢。

更新：第二个问题是由升级固定achartengine 1.2.0。谢谢yoou，丹

Updated: the second issue is fixed by upgrade to achartengine 1.2.0. Thank yoou, Dan.

推荐答案

对于第一个问题，您可能需要升级到1.2.0每晚构建。

For the first issue, you may want to upgrade to the 1.2.0 nightly build.

有关第二个，有： renderer.setBarWidth（widthInPixels）; ，因为这是设置栏宽度的解决方案时，有该系列单款产品

For the second one, there is: renderer.setBarWidth(widthInPixels); as this is the solutions to set the bar width when there is one single item in the series.
