This is what I'm doing:

--heal prediction
  func.healPrediction = function(self)
    if not self.cfg.healprediction or (self.cfg.healprediction and not self.cfg.healprediction.show) then return end
    local w = self.Health:GetWidth()
    if w == 0 then
      w = self:GetWidth()-24.5-24.5 --raids and party have no width on the health frame for whatever reason, thus use self and subtract the setpoint values
    end
    -- my heals
    local mhpb = CreateFrame("StatusBar", nil, self.Health)
    mhpb:SetFrameLevel(self.Health:GetFrameLevel())
    mhpb:SetPoint("TOPLEFT", self.Health:GetStatusBarTexture(), "TOPRIGHT", 0, 0)
    mhpb:SetPoint("BOTTOMLEFT", self.Health:GetStatusBarTexture(), "BOTTOMRIGHT", 0, 0)
    mhpb:SetWidth(w)
    mhpb:SetStatusBarTexture(self.cfg.healprediction.texture)
    mhpb:SetStatusBarColor(self.cfg.healprediction.color.myself.r,self.cfg.healprediction.color.myself.g,self.cfg.healprediction.color.myself.b,self.cfg.healprediction.color.myself.a)
    -- other heals
    local ohpb = CreateFrame("StatusBar", nil, self.Health)
    ohpb:SetFrameLevel(self.Health:GetFrameLevel())
    ohpb:SetPoint("TOPLEFT", mhpb:GetStatusBarTexture(), "TOPRIGHT", 0, 0)
    ohpb:SetPoint("BOTTOMLEFT", mhpb:GetStatusBarTexture(), "BOTTOMRIGHT", 0, 0)
    ohpb:SetWidth(w)
    ohpb:SetStatusBarTexture(self.cfg.healprediction.texture)
    ohpb:SetStatusBarColor(self.cfg.healprediction.color.other.r,self.cfg.healprediction.color.other.g,self.cfg.healprediction.color.other.b,self.cfg.healprediction.color.other.a)
    -- Register it with oUF
    self.HealPrediction = {
      myBar = mhpb,
      otherBar = ohpb,
      maxOverflow = self.cfg.healprediction.maxoverflow,
    }
  end
