Frequent Asked Questions Page

We will publish here common and/or useful questions about our charting library: usage, deployment, tips, features, ... Feel free to contact us at contact (at) crossingcharts.com for any question not listed here.

Licensing and Activation Code

"I am considering purchase of your charting library. I would like to know what "1 year free updates" means exactly. Taking into account current version numbering scheme, what is the highest version number I would be entitled to get for free in the future?"

You may request a free update at any time following the 6 or 12 months after your purchase date (depending on the license purchased). Version is not important. If you purchased version 10 and version 12 is released in 6 months you can update to version 12 for free.

Would I be able to install the library on my computer at work and at home?

You can install your licensed copy of Crossing Charts for .NET in any number of computers. You only need to purchase a new license if need support, updates, and to remove the "Trial Edition" message. Have in mind that support is granted to only one developer per license, so if you are a team of developers working with Crossing Charts for .NET consider purchasing at least 2 or 3 licenses so you don't have to bother the same guy to ask all the questions of your team!

I have purchased a license but I have not received my activation code!

Activation codes are issued in less than 24/48 hours from your purchase. Guaranteed. If you don't receive the email with the code, you should want to check your spam folders, antivirus, etc. Send us an activation code request to contact (at) crossingcharts.com from a different email account.

I have received my activation code but it continues showing "Trial Version" over the charts!

You must delete/uninstall trial edition and download/install retail version which recognizes activation codes. In the email with your activation code you will find the URL to download full version of the library.
If Trial Version message continues, make sure you have indicated your activation code correctly, using LicenseeIdentifier property. Also make sure you don't have any previous/demo versions installed in the GAC and that you have deleted any DLL from a previous version in your hard disk.

Can I use the chart control in Open Source projects?

Due to privacy of the activation codes, only trial edition can be distributed along with your package. End users must purchase a license to avoid Trial Edition message in the charts. Feel free to suggest us an alternate way to distribute a licensed version.

I purchased the library 14 months ago, can I continue using it? Can I update to recent versions?

You can continue using and distributing your licensed copy for ever, of course. But after the first year, you must purchase a new license if you want to update to recent versions as well as to continue receiving support.


Can I use your library in Visual Basic 6?

No. Library is a 100% .NET user component that can only be used from a .NET environment (either .NET Winform application or ASP.NET website). Some users however have reported they have created a proxy .NET library which deals with the .NET library and saves the chart to a GIF file, so it can be loaded in a PictureBox.

Image formats supported

The charts which are generated, would I be able to save them in .BMP or GIF or JPG files?

Yes. Charts may be saved in BPM, GIF, TIF, JPG, PNG, animated GIF as well as SVG (vector) and PDF formats in professional edition.

Are you able to do make some customizations in the library? How much do you charge for them?

Many customers ask for minor customizations for their projects before purchasing the product. That's ok and we usually develop them without extra charge if they are good for the product (an update is then delivered in one or two weeks by email).
