use below script

// Returns a singleton object which provides an entry point for version control functionality.
var cht = aqua.getChart();

// use the object
avl = cht.isChartAvailable();
aqua.console.println(avl);

var ds = aqua.data.newDataSet("country,text,freight,number");

ds.addRowWithValues("US", 10);
ds.addRowWithValues("UK", 20);
ds.addRowWithValues("Japan", 40);
ds.addRowWithValues("Canada", 20);
ds.addRowWithValues("France", 15);
ds.addRowWithValues("Germany", 35);

chart = cht.newChart();
var model = chart.getModel();
model.setDataSource(ds);

chart.getModel().addCategoryField("country");
chart.getModel().addSeriesField("freight");
chart.getProperties().setChartType(1, "area");

chart.properties.setBackgroundColorBottom(260000);
// Set PIE
chart.properties.setChartType(11);

// image will be available after 5 second delay
url = chart.cache(5);
aqua.response.write('<img src=').write(url).write('>');
aqua.response.write('<p>');

// exit
aqua.exit();

Can you reproduce on 3 machines?  and provide screenshots?

// define a data set

MATT - values are non-consecutive, there are a few placeholders in the implementation, for things like Radar charts, Donut charts, etc.
