How to bind data with chart?

Is there some way to bind data from ThingWorx Industrial Connectivity to charts?

 

I have a mashup with several informations (already comunicating with my PLC throught of Industrial Connectivity).

 

I used this guide to try do it but in this case it just show how create chart with manual inputs and I want bind data from my Industrial Connectivity.

 

Does someone know about it?

Hi @einsfele,

 

in generally you need to bind a thing property where the values are logged in a value stream to the   Vuforia chart widget.

For example you can use the QueryPropertyHistory  Thingworx service to connect the values from the value stream to the chart  - here is an  example where Time series chart is used

Re: How to bind data with chart?

at the end I found the topic what I think will also helpful.

In this topic is shown the case  when you have a value stream with values and timestamp. In the mention topic the value are shown  in a DataGrid widget but the principle is the same. So the clue here is that we can define a service  for particular property Name and  using e.g. as Input StartTime and EndTime ( fromat "YYYY-MM-dd HH:mm:ss.SSS Z")

We can call this service from Studio to get the desired data for a property and for a defined  time range:

Here example for test in Thingworx:

And bind the dataGrid Widget data to service getChartDataMinMax in Studio:
