R: Plot Density Graph for data in tables with respect to Labels in tables -

-

i got data in table form in r:

      v1    v2    1  19 -1539    2   7 -1507    3   3 -1446    4   7 -1427    5   8 -1401    6   2  -422    7  22  4178    8   5  4277    9  10  4303    10 18  4431      ....200 million more lines go

i plot density plot value in second column respect label in first column (i.e. each label has on density curve on same graph). don't know how. suggestion?

if understood question correctly, end density heatmap in end. (considering there 200 million observations total , v1 has considerable range of variation)

for try ggplot , stat_binhex:

df <- read.table(text="v1    v2 1  19 -1539 2   7 -1507 3   3 -1446 4   7 -1427 5   8 -1401 6   2  -422 7  22  4178 8   5  4277 9  10  4303 10 18  4431")  library(ggplot2)  ggplot(data=df,aes(v1,v2)) +    stat_binhex() +   scale_fill_gradient(low="red", high="steelblue") +   scale_y_continuous() +    theme_bw()

stat_binhex should work large data , has several parameters presentation (like bins, binwidth. see ?stat_binhex)

the following script reads audio user's microphone , renders oscilloscope on html canvas. the source taken example of mozilla developer network: visualizations web audio api and here fiddle: http://jsfiddle.net/b7j8pktp/ mozgetusermedia (note: code has no fork mechanism different browsers: works firefox) it works fine few seconds , stops rendering. whereas works totally stable: http://mdn.github.io/voice-change-o-matic/ the problem can reduced following code. microphone activation icon (next the address bar in firefox) disappears after 5 seconds: navigator.mozgetusermedia({audio: true}, function() {}, function() {} ); ( http://jsfiddle.net/b7j8pktp/2/ ) this known bug in firefox. take stream getusermedia call , hook window so: navigator.mozgetusermedia({audio: true}, function(stream) { window.stream = stream; // rest of code }, function err() { // handle error }); hopefully can fixed soon. problem we're f
