AchartEngine添加文字与标(AchartEngine add text with supe

是否有可能标，或下标字符添加到AchartEngine中的x轴的标签，就像你在Microsoft Word中那样？

Answer 1:

你可以试试这个

    str = str.replaceAll("0", "⁰");
    str = str.replaceAll("1", "¹");
    str = str.replaceAll("2", "²");
    str = str.replaceAll("3", "³");
    str = str.replaceAll("4", "⁴");
    str = str.replaceAll("5", "⁵");
    str = str.replaceAll("6", "⁶");
    str = str.replaceAll("7", "⁷");
    str = str.replaceAll("8", "⁸");
    str = str.replaceAll("9", "⁹");  

    String  str = "X2";
    String xtitle = str.replaceAll("2", "²");      
    renderer.setXTitle( xtitle);

否则，你可以做

 CharSequence xtitle  =   Html.fromHtml("X<sup>2</sup>");

但你必须改变achartengine库，改变字符串的CharSequence因为CharSequence中不能被强制转换为字符串。
