Help creating Scatter Point chart (org.gicentre.utils.stat) library

enrique_rivers

Hi All, I'm relatively new to processing and can do some of the basics. I'm trying to do something a little more complex and hitting the a snag: I'm getting an error NumberformatException: For input string "Terraced House" I really don't know how to solve this. My code is below. My overall aim is to create a entry box for the user to select the area of the country they require and see what types for properties over a period of months/years. If you need me to post any more information please let me know.

import org.gicentre.utils.stat.*;    // For chart classes.


XYChart scatterplot;

// Loads data into the chart and customises its appearance.
void setup()
{
  size(500,250);   
  textFont(createFont("Arial",11),11);

  // Both x and y data set here.  
  scatterplot = new XYChart(this);

  // Load in data from a file 
  // (first line of file contains column headings).
  String[] data = loadStrings("sample_blpu_inserts.csv");
  float[] changed_date  = new float[data.length-1];
  float[] insert_count = new float[data.length-1];
  String [] description = new String[data.length -1];

  for (int i=0; i<data.length-1; i++)
  {
    String[] tokens = data[i+1].split(",");
    changed_date[i]  = Float.parseFloat(tokens[1]);   
    insert_count[i] = Float.parseFloat(tokens[2]); 
  }
  scatterplot.setData(changed_date,insert_count);

  // Axis formatting and labels.
  scatterplot.showXAxis(true); 
  scatterplot.showYAxis(true); 
  scatterplot.setXFormat("0000");
  scatterplot.setXAxisLabel("\nTime line "+  
                            "(date");
  scatterplot.setYAxisLabel("Number of inserts\n");

  // Symbol styles
  scatterplot.setPointColour(color(180,50,50,100));
  scatterplot.setPointSize(5);
}

// Draws the scatterplot.
void draw()
{
  background(255);
  scatterplot.draw(20,20,width-40,height-40);
}

You'll get a better response if you format your code:

And if you mention which library you are using the subject itself (to attract knowledgeable people).
