How to Exclude Null Value in Chart

[#1]

Hello,

How can I do if I want to exclude the null value in specific data field, such as "NAME"?

I tried two ways:

1. Choose the "Suppress When value is Null" in Chart Properties for the specific dimension. I am not sure if this is the right way to go.

2. Add this line in Script : Where not isnull(NAME) . This one is not working...

Another question is, if I want to exclude null in data fields "NAME", "Time" and "Number". Shall I do "NAME" first, then "Time" thenn "Number". Will the order of (a data field be excluded null values) impact overall values? 

Thanks for your help in advance,

Becky

Try this:

Where Len(Trim(NAME)) > 0 and Len(Trim(Time)) > 0 and Len(Trim(Number)) > 0;

Two answer the second question, i don't think the order matters
