AndroidPlot：在X轴设置标签 [英] AndroidPlot : setting the labels on the X-axis

问题描述

随着AndroidPlot网站是下来，我有点卡住了在这个问题上。几个类似的问题已经被问过，但他们没有得到适当的回答，所以在这里我走了。

With the AndroidPlot website being down, I'm kind of stuck on this issue. Several similar questions have been asked, but none of them were properly answered, so here I go.

我想知道我可以重新标记我的X轴。例如，如果我想绘制了解每月的数据值，我会绘制它像（1，82）为Januari，（2,67） 为Februari，等等。后来，我想在X-标签从改变[1，2，3，...] 到 x_labels = [Januari， Februari，...] 。我怎样才能做到这一点？

I would like to know how I can relabel my X-axis. For example, if I want to plot values about monthly data, I would plot it like (1, 82) for Januari, (2,67) for Februari , and so on. Afterwards, I want to change the X-labels from [1, 2, 3, ...] to x_labels = ["Januari", "Februari", ...]. How can I do this?

哦，并请提供答案而 x_labels 可以是任何东西（如果有每月标签的​​一些具体方法，你永远不知道）。

Oh and please provide an answer for which x_labels can be anything (in case there is some specific method for monthly labels, you never know).

任何人谁可以帮助？
谢谢！

Anyone who could help? Thanks!

推荐答案

想通了自己：

this.getGraphWidget().setDomainValueFormat(new GraphXLabelFormat());

// ...

private class GraphXLabelFormat extends Format {

    private static LABELS = ["Label 1", "Label 2", "Label 3"];

    @Override
    public StringBuffer format(Object object, StringBuffer buffer, FieldPosition field) {
        int parsedInt = Math.round(Float.parseFloat(object.toString()));
        String labelString = = LABELS[parsedInt];

        buffer.append(labelString);
        return buffer;
    }

    @Override
    public Object parseObject(String string, ParsePosition position) {
        return java.util.Arrays.asList(LABELS).indexOf(string);
    }
}
