androidplot setBarWidth [英] androidplot setBarWidth

问题描述

这是我的第一个问题在这样：

this is my first question in SO:

我在Android应用程序中使用Androidplot 0.6.0。我显示的六个月条形图（每月一杆），在这一点上一切顺利，麻烦的是酒吧的宽度（非常薄的），我想做出更广泛的酒吧为更好的外观。我曾尝试以下内容：

I'm using Androidplot 0.6.0 in an Android app. I'm displaying a bar chart of six months (a bar per month), at this point everything is well, the trouble is the bar's width (very thin), I would like make the bars wider for better appearance. I have tried the following:

XYSeries series1 = new SimpleXYSeries(Arrays.asList(domain), Arrays.asList(range), "Title");
BarFormatter series1Format = new BarFormatter(Color.argb(255,0,0,100), Color.LTGRAY);
plot.addSeries(series1, series1Format);

//plot.addSeries(series1, BarRenderer.class, series1Format); //Not in version 0.6.0 
//BarRenderer barRenderer = (BarRenderer) plot.getRenderer(BarRenderer.class); //This return null
BarRenderer barRenderer = new BarRenderer(plot);
if(barRenderer != null) {
   barRenderer.setBarWidthStyle(BarRenderer.BarWidthStyle.FIXED_WIDTH);
   barRenderer.setBarWidth(100); //This don't take effect
}

结果始终是在setBarWidth任何值（）是一样的。

The result always is the same for whatever value in setBarWidth().

先谢谢了。

推荐答案

试试这个

 BarRenderer renderer = (BarRenderer) plot.getRenderer(BarRenderer.class);
    renderer.setBarWidth(20);

更新

试试这个，让乌尔格式化和渲染器。

Try this, make ur formatter and renderer.

class MyBarFormatter extends BarFormatter {
        public MyBarFormatter(int fillColor, int borderColor) {
            super(fillColor, borderColor);
        }

        @Override
        public Class<? extends SeriesRenderer> getRendererClass() {
            return MyBarRenderer.class;
        }

        @Override
        public SeriesRenderer getRendererInstance(XYPlot plot) {
            return new MyBarRenderer(plot);
        }
    }

    class MyBarRenderer extends BarRenderer<MyBarFormatter> {

        public MyBarRenderer(XYPlot plot) {
            super(plot);
        }

        protected MyBarFormatter getFormatter(int index, XYSeries series) {
            return getFormatter(series);
        }
    }

现在

MyBarRenderer renderer = ((MyBarRenderer) plot.getRenderer(MyBarRenderer.class));
    renderer.setBarWidthStyle(BarRenderer.BarWidthStyle.FIXED_WIDTH);
    renderer.setBarWidth(20);
