我目前正在開發一個需要顯示圖表的應用程序，我選擇IguanaUI工具設置爲顯示在應用程序中圖表：需要幫助，定製UI鬣蜥設置工具：
http://www.infragistics.com/products/android/
現在我「M面臨的一些問題與自定義圖表它的自我，這裏目前結果的管理，以實現屏幕截圖：
我的問題：
橙：，如果你看到的Y軸標籤是「切斷」，並且不顯示完整長度。 我想顯示完整的標籤。 （包括由於某種原因從底部切斷的0）
綠色：我想從圖表背景中移除黑色條紋並設置我自己的背景圖像。
設置android:background到圖表對象中的XML佈局文件，設置背景整個對象（包括軸），並且不消除黑色條帶。
我希望圖像僅適用於列區域（不含軸）。
UPDATE： 我發現，你可以申請：
dataChart.setGridDisplayType(GridDisplayType.NONE);
到對象，但是這消除了Axis以及不僅內部網格。
UPDATE2：這是我ChartFragment創建圖表：
public class ChartFragment extends Fragment
{
private Tab tab;
private static final String TAG = ChartFragment.class.getSimpleName();
LinearLayout fragmetLayout, llParameterContainer;
private DataChart dataChart;
private List<String> categories;
private List<Float> column1;
private List<Float> column2;
private List<List<Float>> columnList;
TextView tabName;
public ChartFragment(Tab tab)
{
this.tab = tab;
}

if (container == null) {
// We have different layouts, and in one of them this
// fragment's containing frame doesn't exist. The fragment
// may still be created from its saved state, but there is
// no reason to try to create its view hierarchy because it
// won't be displayed. Note this is not needed -- we could
// just run the code below, where we would create and return
// the view hierarchy; it would just never be used.
return null;
}

有沒有人有這個工具的經驗嗎？ 我一整天都在看他們的文檔，以瞭解如何執行這些任務，但目前爲止沒有結果。
任何幫助，將不勝感激。謝謝。

我已經去過這裏論壇，看到這個答案，這並沒有幫助我。 – 2013-04-24 08:45:08
你能提供你用來創建圖表的代碼嗎？ – alhalama 2013-04-24 20:48:53
