Line chart displaying null values as zeros

[Crystole Roberts]

Hello!

I am building a report that includes a line chart showing the average numerical value for a grouping of records. I am trying to chart two series, each representing a different population. It is working as expected except that one of my lines has 2 null values; however rather than NOT plotting a point for those groups, a zero is being charted. This behavior is not acceptable as it indicates a HUGE problem, where one does not exist. Can you please advise how to remove these zeros from my chart?!?!?

I believe I am using version: 2010.2.745 from 2 August 2010

Thank you so much for your help!

Dear all,

I have that same problem posted at 14 de janeiro de 2011 : Line chart displaying null values as zeros. I am building a report that includes a line chart showing the average numerical value for a grouping of records. So, how to remove these zeros from my chart?

I am using Stimulsoft Report .NET (last version)

Thank you. Regards,

Marcio

Hello,

Can you please send us a sample report template with data or a simple test project, which reproduces the issue?

Thank you.

Hello,

Sorry, can you provide data for your report, which reproduces the issue?

Thank you.

[tynar]

Dears,

Perhaps I am in same situation.

I have table with decimal (nullable) column. Some of the records may contain 0(zero) values, some of them may contain null values. It is important for me to show "0" if it is really zero, and do not show null values as zero. If I set "Hide zeros" property to True then all zeros hidden, otherwise null values are showed as "0". At the bottom of report I made some average calculations on this column, so putting string value is not the solution.

How can I accomplish this task?
