F A Q

Can .netCHARTING be used from traditional ASP scripts?
No, .netCHARTING requires ASP.NET, please see system requirements for more details. You can still make use of the images generated by .netCHARTING in any language however as they are not specific to any platform.

Do I need to be a developer in order to use .netCHARTING?
No, .netCHARTING includes an easy to use control, if you are familiar with HTML or ASP scripting you should have no trouble producing dynamic charts within minutes of downloading the product! .netCHARTING is unique because in addition to performing charting it also performs the required database operations and groups the data for you automatically.

Can I use .netCHARTING at my ISP in a shared hosting environment?
Yes, it was specifically designed to support xcopy deployment. If your web host supports ASP.NET you will be able to use .netCHARTING. We recommend that you test with the trial version in your hosted environment to confirm the product will work for you.

There is a specific charting type or feature I am interested in, will .netCHARTING support this?
We are continually enhancing .netCHARTING based on client feedback. If you have any feature requests please feel free to email [email protected], as your suggestions could end up in the next version of .netCHARTING!

Access to "c:\inetpub\wwwroot\dotnetcharting\web\csharp\temp" is denied (where the value in quotes is a path on your system): Write permissions are required on the directory .netCHARTING is configured to create the charts in. See the install section of this document for instructions on granting write permissions.

CreateControl: A generic error occurred in GDI+: This is a similar case to the previous question. You should ensure that the temp directory is set to a valid path and that the directory has permissions set correctly.

Server Error in '/' Application. File or assembly name dotnetCHARTING, or one of its dependencies, was not found: This error indicates that an application is not created on the directory that contains your /bin directory which in turn contains dotnetcharting.dll. If you follow the instructions for installation via virtual directory an application is created by default. You can also create an application on the directory see here for instructions.

How do I map my database fields onto the x, y axis and other fields?
Use Series.DataFields or if using the DataEngine DataEngine.DataFields properties. Examples:
Simple Chart: Chart.Series.DataFields = "yAxis=myValueField,xAxis=myNameField";
Financial Chart: Chart.Series.DataFields = "Open=myOpenField, Close=myCloseField, High=myHighField.....";

I have licensing questions, what are the options and restrictions?
Please see pricing and purchase for detailed information on the product licensing.

Can I upgrade a web site license to a server license at a later date?
Yes, for the difference in price between what you paid for the web site license and the current cost of the server license. In this case the server license would replace your web site license.

I installed my license but the chart is still branded 'not for production use' why?

Website License:

If you have a 1.x key you must obtain a new key to work with version 2.x from [email protected]
The key must be the bin folder of your application along with the dotnetcharting.dll.
Make sure there is only one key in that folder along with the dotnetcharting DLL.
The license takes effect when the charts are viewed through the licensed domain in the web browser.
The license purchased for a particular domain is specific to YourDomain.com and www.YourDomain.com.
The license will not work on sub domains such as 'server1.YourDomain.com' unless a specific key is purchased for such a URL.

Server License:

Do you have the server version of .netCHARTING? To check open the zip up and see if it contains an install.txt file.
