Please, ANSWER this question AT https://stackoverflow.com/questions/51059331/how-can-i-create-a-history-graph-in-wirecloud-using-history-measurements

Question:
How can I create a history graph in Wirecloud using history measurements?

Description:
I am developing a Fiware application and I am using many Fiware GEs (Wirecloud, IoT Agent, Orion, Cygnus, MondoDB, MySQL) that are integrated locally on my linux pc using docker.

I managed to make Orion to receive measurements from a temperature sensor and store them in a MySQL database through Cygnus.

Now, I would like to create a history graph in Wirecloud using those measurements. I tried to use a History Module to Linear Graph operator that intermediates between an NGSI source operator and a Linear graph widget but I don't know what URL should I use for the HistoryMod Server URL.

I've tried to open the user manual for the History Module operator but the link is broken so I can not read it.

I am posting some images with the wiring, HistoryModule settings, NGSI source settings and the Linear Graph error that I am receiving, for better understanding.

My questions are the following:

What URL should I use for the HistoryMod Server URL?
Am I wiring the components correctly or am I missing something?
