//For some reason I thought we had Friday to work on this as well.  I have been trying various options for radio buttons and cannot get them to work.  I can either make the graphs or the radio buttons.  I was, however, able to fix the colors.  Apparently, for the majority of the colors I had added an extra number at the end, so it looked like fill(x,x,x,x) and the final number resulted in the transparent look.  I will continue to play with this code and attempt to get radio buttons to work to plot each graph as a separate graph.
var table;

function preload() {
  table = loadTable("erodo_results_all.csv","csv","header")
}
function setup() {
  createCanvas(2000,300)
  

  background(255,255,255)
  var rows = table.getRows()
  for (var r = 0; r < rows.length; r++) {
    var x_radial = rows[r].getNum("Radial")
    var height_start = rows[r].getNum("Erod_start")
    var height_500 = rows[r].getString("Erod_500")
    var height_1k = rows[r].getString("Erod_1k")
    var height_5k = rows[r].getNum("Erod_5k")
    var height_10k = rows[r].getNum("Erod_10k")
    var height_50k = rows[r].getNum("Erod_50k")
    var height_100k = rows[r].getNum("Erod_100k")
    var height_500k = rows[r].getNum("Erod_500k")

    //rescale the values to plot rightside up in the canvas and rename columns to x, y for use in drawing
    var x = map(x_radial,0,1990,0,width)

//create the dot representing the point and repeat for the different layers
    ellipse(x,y,10,10)
