Gráfico Google Charts


Recommended Posts

bom dia

estou tentando colocar a data, mas ele só esta aceitando numero array.

tentei mudar alinha data.addColumn('timeofday', 'Time of Day') para data.addColumn('time', 'Time of Day') mas ai o gráfico não aparece.

esta vindo do bando uma string, mas o gráfico não esta aceitando, mudei o formato no banco para Time, mas tb não funciona.. quando eu formato campo no banco como int ai ele aceita..

alguma luz

segue me codigo.
