Hi Gerardo,
Thank you for your interest in Nevron Chart for .NET. Regarding your question - most of the interactivity functionality is part of the Professional / Enterprise editions of the control. In the case of the range selection, it is part of the enterprise edition. Please note that if you're part of an educational/government/non-profit organization you're entitled to great discounts, so please contact
sales@nevron.com if you have questions regarding this.
We hope this helps - please let us know if you have any questions.
Best Regards,
Nevron Support Team
