Problem plotting values on Wirecloud
I have a Orion Context Broker running locally and succesfully connected to Wirecloud. I can show PoI on OpenLayerMap and show attribute values(e.g. temperature) on a "Generic panel".
I tried to plot temperature values on a Linear Graph or in Highcharts, but i ever get some errors. What i did: "NGSI Source" connected to a "NGSI Entity To PoI" and then to OpenLayerMap. From here, from PoI selected, if i add an operator "Value Filter" to filter temperature and then connect a "Generic Panel" it shows correct information, but if i connect it to a "linear graph", it gaves some errors. I tried also to connect "PoI Selected" to a "Gauge chart generator" and then to Highcharts, but i obtain "Widget has not registered a callback for this input"
What's wrong
Thanks for your support!
