OK, I guess you want a pie chart showing percentage of lean mass vs. total body weight, which you're going to caluclate using height and weight?

Anyway, here's the google example (modified a little) which you can put in a template and it should display:

PHP Code:

    <script type="text/javascript" src="https://www.google.com/jsapi"></script>
    <script type="text/javascript">

      // Load the Visualization API and the piechart package.
      google.load('visualization', '1.0', {'packages':['corechart']});

      // Set a callback to run when the Google Visualization API is loaded.
      google.setOnLoadCallback(drawChart);

      // Callback that creates and populates a data table,
      // instantiates the pie chart, passes in the data and
      // draws it.
      function drawChart() {

        // Create the data table.
        var data = new google.visualization.DataTable();
        data.addColumn('string', 'Topping');
        data.addColumn('number', 'Slices');
        data.addRows([
          ['Mushrooms', 3],
          ['Onions', 1],
          ['Olives', 1],
          ['Zucchini', 1],
          ['Pepperoni', 2]
        ]);

        // Set chart options
        var options = {'title':'How Much Pizza I Ate Last Night',
                       'width':400,
                       'height':300};

        // Instantiate and draw our chart, passing in some options.
        var chart = new google.visualization.PieChart(document.getElementById('chart_div'));
        chart.draw(data, options);
      }
    </script>
    <div id="chart_div"></div> 


So you just have to change the parts you want to change. I guess you could create profile variables for height and weight (using the "User Profile Field Manager"), then you can access those values in the template. If you're creating a new template for this then you probably need a plugin to register variables to it and render it. To be honest I'm not sure of the details of adding a profile tab.
