Hi, I´m using processing and LastFm API to call for topAlbums data.

I printed the data in the concole window without any problem, but I want to visualize and use the playcount data, but Have no clue how to do it.

Any help would be great, thanks in advance

Well, try to define precisely the problem: what kind of data have you? Strings? Numbers? Are they correlated?
What kind of graphics do you want? A chart? Pie? Bars? Line? Circles on a surface?

PhiLho, thanks for the reply.

I´m working with the lastFm, json reply. I printed the response for Artist.gettopAlbums and its OK, but I want to use the getPlaycount response for doing circles, lines an so on..

The json structure response is the following:

Album[name='The Best of David Bowie 1969/1974', id='null', url='http://www.last.fm/music/David+Bowie/The+Best+of+David+Bowie+1969%2F1974', mbid='', playcount=13940, listeners=-1,

This what I have so for

// last.fm api key
String api_key = " my api key";
import de.umass.lastfm.*;
import java.util.Collection;
Collection<Track> topTracks;
Iterator<Track> tracks;
Collection<Album> topAlbums;
Iterator<Album> albums;
int i = 0;
String playcount = " " + i;
/*
// Track data
Track track;
Track b;
String track_name;
int track_playcount;*/
void setup()
{
size(500,500);
String artist = "David Bowie"; // store the name of the artist as a string
topAlbums = Artist.getTopAlbums(artist, api_key); // request the top albums from last fm
albums = topAlbums.iterator(); // create an iterator over the elements in topAlbums
topTracks = Artist.getTopTracks(artist, playcount, api_key); // request the top tracks from last fm
tracks = topTracks.iterator();
println(topAlbums);
background(102);
fill(204);
text("Press spacebar...",200,200);
}
void draw()
{
//getTrackInfo(b.getPlays(),b.getName());
}
/*void getTrackInfo (String ar, int play){
//get the track as a Track object
track = Track.getInfo(ar,plays,api_key);
track_name = track.getName(); //get track name
track_playcount = track.getplays(); //get track plays
}*/
void keyPressed() {
if (key == 32) // if that key is a spacebar
{
PImage cover; // declare a PImage to hold album covers
Album a;
background(102); // clear the window and set the background to a nice grey
if (albums.hasNext())
{
a = albums.next(); // get the next album from the iterator and store it in 'a'
fill(204); // set the fill to a lighter grey
text(a.getName(), 50, 50); // print the album name at (50,50)
// retrieve the album cover image and store it in 'cover'
cover = loadImage(a.getImageURL(ImageSize.valueOf("EXTRALARGE")));
// display the album cover
image(cover, 100, 100);
}
}
}
