filterChange(obj) {
      console.log('obj', obj)
      const keys = Object.keys(obj)
      const values = Object.values(obj)
      console.log('keys', keys)
      console.log('values', values)
      let pltKeys = keys[0]
      let pltNum = values[0][0]
      console.log('pltKeys', pltKeys)
      console.log('pltNum', pltNum)
    }
