I would like to show through Wirecloud some sensor´s historical data that I have stored in a Cosmos instance from Orion. The data is stored in a HDFS table.
Looking through the options, I chose the operator History Module to Linear Graph and the widget Linear Graph. Please let me know if there are others better suited for this.
The History Module to Linear Graph requests a HistoryMod Server URL, should I give the Cosmos url? I get an error when trying to open the widget documentation, so I don´t know how to proceed.
I saw that in the Santander example something similar was accomplished through CKAN, using the CKAN Resource Selector and Data Viewer Table widgets. Is this the only way to show historical data in Wirecloud (using CKAN)?
