Hi,
and thanks for quick reply.
interesting solution, but it doesn't work in the way I intend.
Exsample you made, counts total average of all last 1000 samples and then draw it in propotion to real time wind direction. What I wanted, is to count average of all ratio values in different sector's (one sector could be 1 degree area, or 5 deg, what ever is the best at the end... sofware I made have now 30 deg sector size). If the ratio is steady on every wind direction, I would have a nice round circle in polar plot, just one line. But because there are some obstacles disturbing rotor rotating (this is what i'm trying to measure with the VI), line wont be perfect circle any more, but still there would be only one line. Result's I get from metering system would be something like on attachment.
Short exsample. I have received and counted data something like this:
deg ratio
10 0,60
12 0,65
12 0,63
13 0,69
12 0,65
11 0,63
10 0,61
11 0,65
13 0,65
and so on...
What I want to do, is to count average of each sector, max 1000 samples per sector.
Sorting and averaging:
10 deg (0,60+0,61)/2 (max 1000 samples from this wind direction)
11 deg (0,63+0,65)/2 (max 1000 samples from this wind direction)
12 deg (0,63+0,63+0,65)/3 (max 1000 samples from this wind direction)
13 deg (0,69+0,65)/2 (max 1000 samples from this wind direction)
and so on... for every sector.
So, If I want to count ratio average in 1 degree resolution, that mean I would need 360 average unit's to count last 1000 samples of each wind direction. When I have enough data from each wind direction, there would be max 360*1000 samples holded inside LV's memory. Now, if I get even more data, oldest data from each sector would be dropped out (working like FIFO). My VI does exactly this, except resolution is poor and this is wat I would like to improve.
What I have in mind, is something like pointer quided for-loop switch case structure to solve my problem... Switch case, because I can select which window I want to use. But because I dont want to create 360 identical cases, I need something like for loop. In for loop I have to create my software just once, but for loop doesn't let me select which invidual "page" I want to use, like I can do with swich case structure.
