Hello all, I´m trying to use Reagent with highcharts but I don´t know how to update data information with ragent atom. What I´m missing? Change valor -> update gauge

(def valor (reagent/atom 10))

(defn gauge-consumo-config [vl] 
  {:chart {:type "solidgauge"}
   :title {:text "SALA 105"}
   :pane {
          ;:center ["58%" "85%"]
          :size "100%"
          :startAngle -90
          :endAngle 90
          :background {
                       :backgroundColor "#FFF"
                       :innerRadius "60%"
                       :outerRadius "100%"
                       :shape "arc1"
                       }
          }
   :tooltip { :enabled false }
   :credits { :enabled false }
   :yAxis {:stops [[0.1 "#55BF3B"]
                   [0.5 "#DDDF0D"]
                   [0.9 "#DF5353"]]
           :lineWidth 0
           :minorTickInterval nil
           :tickPixelInterval 400
           :tickWidth 0
           :title {:text "" :y -70}
           :labels {:y 16}
           :min 0
           :max 100
           }
   :series [{:name "Consumo"
             :data [vl]
             }]
   :plotOptions {
                 :solidgauge {
                              :dataLabels {:y 15
                                           :borderWidth 0
                                           :useHTML false
                                           :format "{y} %"}
                              }
                 } 
   })

(defn gauge-consumo-did-mount [this]
  (js/Highcharts.Chart. (reagent/dom-node this) (clj->js (gauge-consumo-config @valor))))

(defn gauge-consumo-render []
  [:div {:style {:width "200px" :height "200px" :margin "0 auto"}}])

@fabrao: I am getting an error when running your code (`highcharts.js:8 Uncaught Error: Highcharts error #17`), what scripts are in your index.html file to bring in highcharts?
