Seems like a good tool but also appears a bit buggy - if you change the values of a statepoint in the table it doesn't update the chart.
We use a dedicated program called HDPsychart which is also a bit buggy but more powerful. It also has a really useful feature where you can pull TMY3 bin data into excel for annual energy calculations.
