AchartEngine注释 [英] AchartEngine annotations

问题描述

我到处看，唯一的信息，我能找到说，通过以下code到屁股它们

everywhere i look, the only information I can find says to ass them via the following code

series.addAnnotation("Hello!!", 1, 1);

然而，当我在code尝试（使用适当的系列名称）我得到一个错误消息，指出不支持addAnnotation。是否有人可以清除这件事给我吗？谢谢！

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!

推荐答案

您必须下载最新版本的库。例如，让夜晚构建从<一个href="https://repository-achartengine.forge.cloudbees.com/snapshot/org/achartengine/achartengine/1.1.0/"相对=nofollow>这里。

You must download a recent version of the library. For example, get the night build from here.

在你的code，替换最后一行（一个在您返回图表视图）其中：

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);
series.addAnnotation("Vacation", 6, 30);
return ChartFactory.getBarChartView(context, dataset, renderer, Type.STACKED);
