Generally, the tool is as good as the hands that wield it. Before
AmiBroker, I had a couple of custom tools which I'd written in .NET
which included a custom charting component which was deadly fast. I
left my own tools to collect dust because my time trades for a
significant premium over $229. The amount of time I spent making my
charting component faster than greased lightning was at the expense of
time spent doing worthwhile research.
.NET can also draw in plain old COM components. TeeChart, long the gold
standard for charting components, releases its WinForms .NET as a simple
.NET wrapper.
The problem with "some other charting packages" is they have likely used
open-source components like nChart, which are great for displaying
static charts, but are too slow for displaying large data sets which
update frequently. I think you can even pull in the Excel charting
component.
It was not too long ago that I recall the great debate about how C++ was
so slow compared to C... New programming tools tend to used to create
less efficient programs, and that improves as programmers' understanding
increases. It turns out that everyone complaining about C++ speed were
passing massive templated data structures by value instead of reference,
and C++ wasn't actually the catalyst for the second coming.
Corollary: most programmers are crap.
