I would say (rho,theta), but I want theta to be from the Y-axis not the X-axis.
But given that, theta-from-Y is the wind direction and rho is the windspeed.
Now, what to do about the time component?
That's easy: you need a Z-axis.
Which means that you end up with a double helix!
Then you could merge those two graphs.
@Reg Do you know any graphing software that would let me produce a helix or double-helix given the right inputs?
I imagine a wind vane spinning around the compass to indicate the direction, the magnitude of the arrow indicating velocity, and the helix is what happens when you graph it against time. If you graph both sustained and gust velocities (yes, velocities, not speed: these have direction) then you would have a clock with two hands on it of varying lengths. If you stack a bunch of these up to represent time, you have a double-slinky.
Hm, I seem to have found a Gmbh company.
Oh good, they have an EN version so I don't have to be dumb.
Think of it as a wind rose where you pull up the slinky.
I'm trying to make a plot that can display both wind speed and wind direction over time. A colleague suggested adding a line pointing in the wind direction to each point on a time-series plot of wind speed.
I thought it would be fairly simple to calculate the line. I used trig formulas from here...
I have 3 vectors , one for angles of Phi , another for angles of Teta , and the last one a vector of points in the Y axe ,after computing the points of Teta & Phi with a function :
for teta = 0 : 10^-2 : pi/2
for phi = 0 : 10^-2 : pi/2
Y(current) = v*sin(phi)*sin(teta);
Can somebody help me and write code for this 2 picture in WinEdt (latex) (this is from Mathematica, I write in Mathematica, but I don't know write this code in WinEdt). I tried with "parametricplotThreeD" and I don't know how write code. Help :(
Sorry, I don't speak english very well..
