I need to specify a parameter in a line chart in Visual Studio 2013. I have looked on MSDN and googled, and no help. MSDN gives information that must only work for a previous version as far as I can tell. I right click and navigate everywhere in my report environment, and can't find anywhere where I can add a parameter.
I need to know this because when I run my web page to view a line chart, I am getting an error that I am trying to use a parameter that has not been specified. I thought that SSRS would pick it up automatically from my stored procedure which I specified, but apparently not.
