Charts

I'm missing something. Here's the instructions for creating a chart:

To create a chart, proceed to Datasource tables and click Add Chart button. On Chart Type tab select the type of chart to build.
I don't see 'Chart Type'. What am I missing?

With the chart selected in the Datasource tables, select the Next button. I believe to get to the different types you'll have to do that twice, because you will see the query page after hitting it once.
