Hi,
Graphing is a huge topic. Depending upon your needs, you have several
options.
If you just need some basic generic charts, line, bar, pie, and aren't picky
as to the quality (don't mind some overlapping text, wasted control
real-estate, and making some compromises), then there are many low cost
charting tools on the market. I suggest you check out
www.componentsource.com for a large list.
If you are writing a package where charting plays a large role, requires a
large amount of flexibility, or needs to handle larger amounts of data
clearly and professionally, then definitely research ProEssentials at
www.gigasoft.com. We tailor more to the technical, financial, and large
information system type applications, but we do attract customers from the
entire spectrum.
We sale a Lite version of the ProEssentials tool for $149, which if you do
your research, you'll find is a huge bargain. As this tool will provide
quality output, maximum speed, the largest amount of features on the market,
but is limited to 1000 data points per instance of a control. We also sale
a Standard version for $399 with a 8000 data point limit, as well as a Pro
version for $1299 which is unlimited.
Good luck with your project.
best regards,
