title: draw a bar chart in java applet with array
body: <p>I have created a code that looks for word patterns in a passage of text, it discounts anything that is not a letter. So basically the text 'hello world it is a lovely day' would give 1, 2, 1, 2, 1.
  the applet displays it in a basic text format, what I want is for it to show the results in a bar chart.</p>
  
  <p>I know how to to it in principle, I need to link my data from my array and get my applet to draw it and then have the width increase depending on the value given (the cart will be drawn horizontally, with the the main base, where the bars start from being vertical, if you understand what i mean)</p>
  
  <p>my problem is, I don't know how to do this code, I don't know how to start it off, any help would be much appreciated. </p>
  
  <p>here is my code</p>
