i'm developing web interface shows spoken language of person , includes charts. have choosen google charts , design has following image

objective

i searched in google charts api , started use pie charts removing slices options , far achieved charts following image:

enter image description here

the problem when using removing slices options have set 2 quantities create chart. first 1 number appears in image , second 1 hidden. datatable built code:

...                 var average= math.round( (porcentajes['speak'] + porcentajes['read'] + porcentajes['write'])/ 3 );                 var remaining_average= 100 - average;                     var data = google.visualization.arraytodatatable([                         ['pac man', 'percentage'],// don't see appears                         [language, average], //language german or english                         ['', remaining_average]                       ]); ... 

so in summary want achieve align center or add styles chart without showing second quantity.

or

is there another option create chart this?

thanks in advance , appreciated!

update

suppose full circle 100% , letters means:

e: written abilities (e stands word escrito in spanish)

l: reading abilities (l stands word leido in spanish)

h: spoken abilities (h stands word hablado in spanish)

the graph displays how person can communicate in determinate language, , number in middle of circles average of 3 aspects (e, l, h)
