percentage and performance problems

Hello
Is there any way to not show the symbol that indicates the percentage in each circle of the graph?
I would also like to comment that I have serious performance problems when I use the following attributes:
apsv_shadowed="true"
apsv_shadow_distance
apsv_shadow_angle
apsv_shadow_radius
apsv_shadow_color

On a tablet nexus 9 with Android 7.1: High battery consumption and system slowdown, especially when using fragments (with two or three fragments is enough to have those problems).
Congratulations for your library and sorry for my bad English.
thanks, regards.

未指定檔案、測試或進入點。在所描述的 Nexus 9 和 Android 7.1 設定上，使用列出的陰影屬性重現該報告，並檢查程式庫的 circle-label 行為。當可以省略百分比符號，且回報的電池、變慢和 fragment 問題已獲得解決或被精確描述時，即視為完成。
