How to make optical power chart

Here’s my code:

label: “‘Optical Power’”
slices:
1_normal:
color: “‘#e8702a’”
filter: VirtualParameters.OpticalPower >= -15
label: “‘Normal’”
2_warning:
color: “‘#0c457d’”
filter: VirtualParameters.OpticalPower < -15 And VirtualParameters.OpticalPower
> -30
label: “‘Warning’”
3_critical:
color: “‘#0ea7b5’”
filter: VirtualParameters.OpticalPower <= -30
label: “‘Critical’”

Was this entered in Admin > Config > Edit Charts?

Did you update Admin > Config > Edit Overview?

Hi, on “edit overview”:

online:
  label: "''"
  charts:
    - '"online"'
    - '"potenciasONT"'

then, on “edit charts”:

online:
  label: "'Online status'"
  slices:
    1_onlineNow:
      color: "'#31a354'"
      filter: Events.Inform > NOW() - 90 * 60 * 1000
      label: '"Online(90min)"'
    2_past24:
      color: "'#a1d99b'"
      filter: Events.Inform > NOW() - 90 * 60 * 1000 - 24 * 60 * 60 * 1000 AND
        Events.Inform < NOW() - 90 * 60 * 1000
      label: '"Offline < 24hs"'
    3_others:
      color: "'#e5f5e0'"
      filter: Events.Inform < NOW() - 90 * 60 * 1000 - 24 * 60 * 60 * 1000
      label: '"Offline > 24hs"'
potenciasONT:
  label: "'POTENCIAS'"
  slices:
    1_normal:
      color: '"#77dd77"'
      filter: InternetGatewayDevice.WANDevice.1.X_GponInterafceConfig.RXPower >= -26
        AND InternetGatewayDevice.WANDevice.1.X_GponInterafceConfig.RXPower <
        -15
      label: '"POTENCIA OK"'
    2_alta:
      color: '"#FF7F14"'
      filter: InternetGatewayDevice.WANDevice.1.X_GponInterafceConfig.RXPower < -12
        AND InternetGatewayDevice.WANDevice.1.X_GponInterafceConfig.RXPower >=
        -15
      label: "'POTENCIA ALTA'"
    3_baja:
      color: '"#FF7624"'
      filter: InternetGatewayDevice.WANDevice.1.X_GponInterafceConfig.RXPower > -28
        AND InternetGatewayDevice.WANDevice.1.X_GponInterafceConfig.RXPower <
        -26
      label: "'POTENCIA BAJA'"
    3_fueraDeRango:
      color: '"#F72D0D"'
      filter: InternetGatewayDevice.WANDevice.1.X_GponInterafceConfig.RXPower <= -28
        OR InternetGatewayDevice.WANDevice.1.X_GponInterafceConfig.RXPower	>=
        -12
      label: "'FUERA DE RANGO'"

This is working on Huawei ONTs, probably you will have to change parameters
