We've opened a support ticket with a response time for 24hrs, we even provided a sample project, but we are getting no response from telerik after more than 48hrs.

The chart is meant to display two line graphs indicating a sales comparison between different months.

The problem is, when we compare Janurary and March, there is no error, but when we compare either Janurary or March against Feburary, a 'series.Index' nullreference error is thrown. There are 31 entries for the xaxis, all the entries have a number assigned (including Feburary, where 30, 31 has values '0'). There are some instances that the graph is displayed correctly, without any modification in code and in the numbers, but most of the time it crashes the application. It's an irregular crash that we cannot pin point what the problem is.

Since the sales are displayed in Japanese yen, the profit number is as high as 100,000 - 200,000. We are not sure, but is the chart having problems handling large numbers?

Does anyone else have a similar experience? Moreover, our subscription is about to run out in a few days, but hopefully they will provide us with a version of RadChart that does not crash irregularly, instead of asking us to renew the subscription to get the component that actually works.

Hi Peter,

We are sorry for not addressing your questions within the promised 24 hours. Truth is that we guarantee 24 hour support on weekdays only. This is duely noted on our Technical Support Options page.

In general, this time is guaranteed for our support ticketing system as it assigns a response time depending on your license. The Forums get a default of 72 hours, so it will be better to use the support system in order to get a faster reply. More on the topic you can find here: IMPORTANT INFORMATION ON USING THE TELERIK FORUMS

We are looking at your questions right now and will reply back shortly.

Sorry for the delay.


Best wishes,
Vassil
the Telerik team

Thank you for the reply. Since the ticket response deadline showed 24 hours, we expected a reply within that time. If the weekend response deadline is not guaranteed, perhaps it should show 72 hours instead of 24 hours when we submit a ticket during the weekends? Moreover, we submitted the ticket on the 4th of April, which is Friday.

Nevertheless, the error with RadChart does not occur on the asp.net web version, the error occurs with just the WinForms version. Please reply to the support ticket and help us resolve this problem as fast as possible.
