I have defined an attribute and the values are coming from table. Again, I have a PI tag too and values are the same time stamp as my attribute. I wanted to display 2 components in Pi Vision via XY plot graph. I pulled out the attribute and tag to the display area and set the time stamp , where values are available with same time range. But didnt see the XY graph as scattered plot . I see nothing in my graph meaningful. Please can anyone assist?
