I have a CSV/TSV file with 6 points of data for each line in the following synax:
title,
negRadius, posRadius, neutralRadius,
x,
y
At this point columns 2, 5 & 6 are important.
5 & 6 relate to the X / Y coordinates that I would like to plot.
2 gives the radius of an ellipse to plot at the given X,Y.
Using the code (below) & data (linked) I am given an error reading: "ArrayIndexOutOfBoundsException: 6" The number changes if I alter the column value I am pulling first (2,5 or 6) so the error is probably tied to that - but I have no idea how to fix it.
Code:
Table locationTable;
int rowCount;
void setup() {
size(640, 400);
locationTable = new Table("nyc_data.tsv");
// The row count will be used a lot, store it locally.
rowCount = locationTable.getRowCount();
}
void draw() {
background(255);
// Drawing attributes for the ellipses
smooth();
fill(192, 0, 0);
noStroke();
// Loop through the rows of the locations file and draw the points
for (int row = 0; row < rowCount; row++) {
float x = locationTable.getFloat(row, 6); // column 6
float y = locationTable.getFloat(row, 5); // column 5
ellipse(x, y, 9, 9);
}
}
With additional 'Table' code based on Fry's ch3. (shown below)
Can someone help me plot ellipses to the X,Y (column 5&6) from the .tsv? My programming ability is quite limited... but I'll do my best to work with any help I'm given.
Much appreciated!!!

Table code:
class Table {
int rowCount;
String[][] data;
Table(String filename) {
String[] rows = loadStrings(filename);
data = new String[rows.length][];
for (int i = 0; i < rows.length; i++) {
if (trim(rows[i]).length() == 0) {
continue; // skip empty rows
}
if (rows[i].startsWith("#")) {
continue; // skip comment lines
}
// split the row on the tabs
String[] pieces = split(rows[i], TAB);
// copy to the table array
data[rowCount] = pieces;
rowCount++;
// this could be done in one fell swoop via:
//data[rowCount++] = split(rows[i], TAB);
}
// resize the 'data' array as necessary
data = (String[][]) subset(data, 0, rowCount);
}

return rowCount;
}
// find a row by its name, returns -1 if no row found
int getRowIndex(String name) {
for (int i = 0; i < rowCount; i++) {

return i;
}
}
