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.

No file, test, or entry point is named. Reproduce the report on the described Nexus 9 and Android 7.1 setup with the listed shadow attributes, and inspect the library's circle-label behavior. Done means the percentage symbol can be omitted and the reported battery, slowdown, and fragment issues are addressed or precisely characterized.
