Hello @dimitris!

Yes it is possible as double line, line & bar and radar/windrose.

Have a good day.

PS: could you, please, make sentences with a minimum of empathy (you know, "hello", "please", "thank you")? The miserable human that I am needs this to not feel like being taken for a bot   

Hello Pierre

Thank you for your reply (and sorry if you felt like a bot. My mistake. I was in a hurry  ☹ )

What I have tried:
Go to Daily data TAB and chose Bi line tab. In measurement 1, In Module I chose wind and in measurement wind strength. I want to do the same in measurement 2 and choose wind gust but there is no such a value.

Ah ok, I see what you mean, the question was too short to allow me to understand correctly, sorry   ???? 

In fact, what you want to do (displaying wind strength and gust - so speed dimension for the 2 measurements) can be achieved with almost all types of charts. But at one condition: the station you collect must have the capability to measure it. If you don't have the wind gust in the dropdown list it's because the station doesn't publish it (and likely doesn't measure it). It is, unfortunately, the case with OpenWeatherMap "virtual stations". If you want to have this information you must collect data from a true station (Netatmo, WeatherFlow, most of the WeatherUnderground stations and, of course, stations which export data via files).

Hello again

I am using my diy weather station that sends data to wunderground.

I am sure I am sending wind speed and wind gust, because I can see those values in wunderground.

Could you tell me the WU identifier of you station? I will get an eye on it.

This station sends only wind data (speed, gust & direction). It's an ultrasonic (Gill instruments) anemometer.

I have done a test and yes, the gust strength is correctly collected. Just curious, have you read this? Are you really in scientific mode?

Oh sorry. I wasn't in scientific mode.

I didn't read all the manual pages. 

Thank you very much for your great plugin. You 've saved me hours of work.

If your happy with it, you know what to do 😉
