Final Processing Code!

In processing, we decided to code a data. We coded a bar graph, a data visualization of wine and grapes. Data talks about if grapes has affected the price of wine. We pulled the data online and uploaded in processing.

CODE:

//ap.data.3.Food.txt
Table foodTable = null;
color barColor = #63EAFF;
color highlightColor = #360524;
float dataTipX = 0;
float dataTipY = 0;
int dataTipYear = 0;
float dataTipPrice = 0;

void setup () {
 size(900, 500);
 foodTable = loadTable( “ap.data.3.Food.txt”, “header,tsv” ); // tsv-tab seperated value
 foodTable.trim(“series_id”);
} // setup()

void draw () {
 background(255);
 float barWidth = 8;
 float x = 0;
 int startYear = 1996;
 String seriesId = “APU0000720311”;
 drawBars( foodTable, seriesId, x, barWidth, startYear ); 
 seriesId = “APU0000711417”;
 drawBars( foodTable, seriesId, x+barWidth, barWidth, startYear);
 if ( dataTipX > 0 ) {
 drawDataTip (dataTipX, dataTipY, dataTipYear, dataTipPrice);
 }
 dataTipX = -1;
 dataTipY = -1;
}

void drawBars(Table foodTable, String seriesId, float x, float barWidth, int startYear ) {

int i=1;
 int numMonths = 12;
 float averagePrice = 0;
 for ( TableRow row : foodTable.findRows( seriesId, “series_id” )) {
 int year = row.getInt(“year”);
 if ( year >= startYear ) {
 float price = row.getFloat(“value”);
 averagePrice += price;
 if ( i % numMonths == 0 ) {
 averagePrice /= 12; //averagePrice = averagePrice / 12

String month = row.getString(“period”);
 float h = averagePrice * 30;
 float y = height — h;
 fill( barColor);
 setHighlight( x, y, barWidth, h);
 rect(x, y, barWidth, h);
 dataTip( x, y, barWidth, h, year, averagePrice);
 x = x+20;
 averagePrice = 0;
 }
 i++;
 }
 } // for loop
} //drawbars

void setHighlight( float x, float y, float barWidth, float h) {
 if (mouseX < x +barWidth && mouseX > x && mouseY < y+h && mouseY > y) {
 fill(highlightColor);
 }
}

void drawDataTip ( float x, float y, int year, float price ) {
 fill(255);
 rect (x, y, 100, 60);
 fill(0);
 text ( year, x+5, y+15);
 text ( price, x+40, y+15);
}

void dataTip( float x, float y, float barWidth, float h, int year, float price) {
 if (mouseX < x +barWidth && mouseX > x && mouseY < y+h && mouseY > y) {
 dataTipX = mouseX;
 dataTipY = mouseY;
 dataTipYear = year;
 dataTipPrice = price;
 }
}
