[英]Adding % sign to Y-Axis Labels in Bar Chart AChartEngine
I am working on an android app and using AChartEngine for Charting. 我正在开发一个Android应用程序,并使用AChartEngine进行图表绘制。 The Bar Chart is drawn on the basis of the dynamic data coming from a server.
条形图是根据来自服务器的动态数据绘制的。
Th Y-Axis labels are set to be shown from 0 to 100 and no of labels are 11 s it shows 0..10..20..30..40..60..70..80..90..100 as Y-Axis Labels. Y轴标签设置为从0到100显示,标签个数都不是11,它显示0..10..20..30..40..60..70..80..90 .. 100作为Y轴标签。 Is it possible to set custom Y-Axis labels such that it adds '%' sign after the Y-Axis title value so that it shows,
是否可以设置自定义Y轴标签,以便在Y轴标题值之后添加'%'符号,以便显示,
0%..10%..20%..30%..40%..60%..70%..80%..90%..100% as Y-Axis label values. 0%.. 10%.. 20%.. 30%.. 40%.. 60%.. 70%.. 80%.. 90%.. 100%作为Y轴标签值。
How to do it?? 怎么做??
In order to set custom labels on the Y axis, you just need to use the following method: 为了在Y轴上设置自定义标签,您只需要使用以下方法:
mRenderer.addYTextLabel(10, "10%");
mRenderer.addYTextLabel(20, "20%");
...
Also, if you want to hide the default labels, do this: 另外,如果要隐藏默认标签,请执行以下操作:
mRenderer.setYLabels(0);
All what you need to do is: Enjoy ;) 您需要做的就是:享受;)
renderer.addXTextLabel(0, "0");
renderer.addYTextLabel(10, "10%");
renderer.addYTextLabel(20, "20%");
renderer.addYTextLabel(30, "30%");
renderer.addYTextLabel(40, "40%");
renderer.addYTextLabel(50, "50%");
renderer.addYTextLabel(60, "60%");
renderer.addYTextLabel(70, "70%");
renderer.addYTextLabel(80, "80%");
renderer.addYTextLabel(90, "90%");
renderer.addYTextLabel(100, "100%");
renderer.setYLabels(0);
I haven't actually done a lot with AChartEngine, but a quick glance at the source code suggests you could extend BarChart
to accomplish what you're after. 我实际上对AChartEngine并没有做很多事情,但是快速浏览一下源代码就可以建议您扩展
BarChart
来完成您要完成的工作。
Have a look at the getLabel(double label)
method located in AbstractChart
( BarChart
extends XYChart
, which on its turn extends AbstractChart
). 看一下
AbstractChart
中的getLabel(double label)
方法( BarChart
扩展了XYChart
,而XYChart
又扩展了AbstractChart
)。
/**
* Makes sure the fraction digit is not displayed, if not needed.
*
* @param label the input label value
* @return the label without the useless fraction digit
*/
protected String getLabel(double label) {
String text = "";
if (label == Math.round(label)) {
text = Math.round(label) + "";
} else {
text = label + "";
}
return text;
}
I would start with something naive to see how that works out; 我将从一些幼稚的事情开始,看看它是如何工作的。 eg simply append
"%"
on the result of above: 例如,简单地在上述结果上附加
"%"
:
@Override protected String getLabel(double label) {
return super.getLabel(label) + "%";
}
Only thing I'm not too sure about is whether the same method is used to generate labels for the X-axis. 我不太确定的是,是否使用相同的方法为X轴生成标签。 If that's the case, you'll probably need to do something slightly smarter to enable it just for the axis you're interested in.
如果是这种情况,您可能需要做一些更聪明的操作才能针对您感兴趣的轴启用它。
