Uibuilder + apexCharts not working

Hi guys,
i'm trying a zoomable time series demo from apex zoomable time series but some how it's not working and i cant really debug because of my limited javascript + html skillls, no error is reported.

What i have done is adopting this example Creating charts with uibuilder and apex charts, replacing it with my time series demo but nothing is really displayed apart from the heading. I need some help to figure out why my demo example is not working, any hints will highly be appreciated thanks!

Here is my code:

Best regards,

Hello .. What is dates in your code? .. its not defined anywhere.
Better to define it as an empty array at the start data: [] and then populate it with data as you receive them from Node-red :

// Process new messages from Node-RED
        uibuilder.onChange('msg', function(newVal) {
            console.log("Msg received from NR", newVal.payload)
            if (newVal.payload) {
                // Add new element
                let newData = vueApp.series[0].data
                // Lose the first element if there are to many !!
                if (newData > 50) newData.shift()
                vueApp.series = [{
                    data: newData

Furthermore .. the data need an x and y value to be plotted so i recommend you send your data as an object from the Change Node to uibuilder.

   "y": ($random()*10)+($random()*10),
   "x":$moment().format("YYYY-MM-DD HH:mm:ss") 



You aren't updating any data so it can't display anything. As @UnborN points out, you need to listen to the data coming in from Node-RED and pass it to the data object you are using for your chart.

Cheerz guys, it works now and im starting to get the hang of it.
Great forum!
