How can I update my chart?

@doridol that is USE, not really define

I don’t like side effects… create on 1st use… ugh.

also, you will UPDATE in notification, but need to CREATE in getdom, or somewhere

@sdetweil oh… it is very difficult to update chart… really thanks for your help I seem I have to study more…

@sdetweil I have really really last question I changed my socketNotificationReceived like this

socketNotificationReceived: function(notification, payload) {
            if (notification === "TEXT_RESULT") {
                this.textDataRecived = payload;
                this.loaded = true;
            }

            
            if(count < 2)
            {
                this.updateDom();
                count = count + 1;
            }
            else
            {
                this.myChart.data.datasets.data = this.textDataRecived
                console.log(this.myChart.data.datasets.data)
                this.myChart.update();
            }
        },

and console.log(this.myChart.data.datasets.data) successfully print this.textDataRecived but my chart is not updated in the screen why???
