detect peaks and valleysI have histogram shown in this figure : http://i1069.photobucket.com/albums/u472/tina12354/h1_zps40094c32.png #2 20120921 22:11:25
Re: detect peaks and valleysHi tina123; In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #4 20120921 22:18:44
Re: detect peaks and valleysYou could search through the discrete data for maximum values and minimum values. You can get the peak by just counting how many of each type of numbers there are. There are 4 ones, this is the most. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it.

Re: detect peaks and valleysA histogram charts occurences. One has 4 occurences as you see in the histogram. It is a peak not a valley. In mathematics, you don't understand things.

Re: detect peaks and valleysSo i think check occurrence of each data .. valley will be there where occurrence would be minimum, #10 20120922 23:18:04

Re: detect peaks and valleys
Well if we consider only useful data . then its from i = 0 ; i < 46 ; i++ , get minimum value. it would be 2 . which will be our valley . but for and 21 will be our maxmum peak . #13 20120922 23:31:18

Re: detect peaks and valleysHere is a histogram like yours, it contains values from 0 to 46.
That I cannot do. That drawing is not labelled so how can tell what the peaks are? I can pick them out but I do not know what numbers they are. Also I do not have the data and I can not get from that picture. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it.

Re: detect peaks and valleysYou say that on the x axis we go from 0 to 53. Does that mean the whole black area or just the red? In mathematics, you don't understand things. You just get used to them.

Re: detect peaks and valleysI can not see bins it it too small. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it.

Re: detect peaks and valleys
Well actually i maked histogram in range 0 to 180 . and to make histogram i consider bins 180 . so bins size is so small . #22 20120923 00:18:52
Re: detect peaks and valleysI have marked off two peaks, I can not see what number they are. In mathematics, you don't understand things. You just get used to them.
