The GraphInquire ActiveX is a software that enhances a Microsoft Chart element by allowing users to zoom in, zoom out, and scroll to inquire about the exact form of a series. It also supports displaying multiple series interactively and includes time scale support.

One useful feature that I appreciated was the ability to display multiple series interactively by actions of the user. Additionally, the series can be scaled automatically over a period of time. It's also worth mentioning that weekdays and legal holidays are displayed, and there's a legend to make it easier to understand the data.
The GraphInquire ActiveX supports localizations for the USA and Germany, which makes it even more convenient to use. What impressed me was that the actual display can be printed out at any time, which is crucial when dealing with large amounts of data.
And the best part- not only can it display series, but also functions. With no constant x-axle distance, the software can display x-axis as time, ordinal numbers and strings. Overall, I found the GraphInquire ActiveX to be a robust tool that helps to visualize data in a more impressive way.
