Buenas
El problema que tengo es el siguiente no puedo personalizar mi ejex ya que solo quiero que m muestre las horas
String labels = "00:00,00:10,00:20,00:30,00:40,00:50," +
"01:00,01:10,01:20,01:30,01:40,01:50," +
"02:00,02:10,02:20,02:30,02:40,02:50," +
"03:00,03:10,03:20,03:30,03:40,03:50," +
"04:00,04:10,04:20,04:30,04:40,04:50," +
"05:00,05:10,05:20,05:30,05:40,05:50," +
"06:00,06:10,06:20,06:30,06:40,06:50," +
"07:00,07:10,07:20,07:30,07:40,07:50," +
"08:00,08:10,08:20,08:30,08:40,08:50," +
"09:00,09:10,09:20,09:30,09:40,09:50," +
"10:00,10:10,10:20,10:30,10:40,10:50," +
"11:00,11:10,11:20,11:30,11:40,11:50," +
"12:00,12:10,12:20,12:30,12:40,12:50," +
"13:00,13:10,13:20,13:30,13:40,13:50," +
"14:00,14:10,14:20,14:30,14:40,14:50," +
"15:00,15:10,15:20,15:30,15:40,15:50," +
"16:00,16:10,16:20,16:30,16:40,16:50," +
"17:00,17:10,17:20,17:30,17:40,17:50," +
"18:00,18:10,18:20,18:30,18:40,18:50," +
"19:00,19:10,19:20,19:30,19:40,19:50," +
"20:00,20:10,20:20,20:30,20:40,20:50," +
"21:00,21:10,21:20,21:30,21:40,21:50," +
"22:00,22:10,22:20,22:30,22:40,22:50," +
"23:00,23:10,23:20,23:30,23:40,23:50";
que todos los valores es enviado por otra clase, el grafico me sale casi ok, lo que quiero es que en el eje "x" solo me muestre las horas, pero tomando en cuenta todo los valores de x_labels para hacer el grafico
es decir que en el grafico el eje x solo muestre "00:00,01:00,02:00,03:00,04:00,05:00,06:00,07:00,0 8:00,09:00,10:00,11:00,12:00,13:00,14:00,15:00,16: 00,17:00,18:00,19:00,20:00,21:00,22:00,23:00,00:00 ";"
tb tengo una variable dias, lo que quiero es que con los elementos del ejex haga la siguiente operacion, que si son 2 dias que muestre 2 veces desde el 00:00 al 23:00
en openflashchart lohacia de la siguiente manera
Cita: .....
"&x_label_style=10,#0101DF,2,"+ 6 * Integer.parseInt(dias)+",#FFFFFF& \n"
"&x_labels="+x_labels+",00:00& \n"+
...........
