How do I create a dashboard with a graph where I can have sidebar filters?

[vstrash]

How do I create a graph where I can have sidebar filters? I am using a csv excel file. My y is sum value with the x being a filterable option. I'd like to have several search bars where I can filter different categories and have the sum values display accordingly. I am wondering if there is a search command or where is the filter set up option when creating a dashboard. I have been able to generate a graph by itself, but not filter on that graph.

The Splunk dashboard with input/filter is called form and here is the procedure, Splunk documentation, to create the same.
