Dynamic Line Chart: Using Slicers and Parameters

[Kyle_AspirEDU]

Good morning, 

First, my apologies if this has been asked and answered, but I can't seem to find a guide/tutorial for exactly what I am trying to do. 

Second: my goal. 

I would like to create a single-line chart that has a set range of dates (X Cord - dates some from my data) and the Y cord is changed by a Slicer using a parameter I created from several different data points. Basically, I want to use the slicer to change the Y cord showing a different data type within the same line chart.  Below you can see it working (bottom line chart) when I manually add the data point to the chart, but then when I use the slicer, with the parameter, to select a single data point, nothing is displayed. I have made sure the slicer is filtering the correct line chart. 

I think the issue might be that the data that makes up the parameter is not summed like it is in the working line graph. But for the life of me I can't figure out a way to make every data point summed within the parameter. 

Your help would be greatly appreciated.

Thank you, 

Kyle

@Kyle_AspirEDU , Please check field parameters can help

Thank you @amitchandak  for the reply, but I have seen this before, your videos are very helpful, but it doesn't seem to fix the issue I am experiencing. 

I can get the line chart to use the slicer/parameter for the X cord (as you have shown in your video), but What I really want is to sum the from each individual data set, from the picture "Tagged Notes" and display that data for each data set, along the X cord of the line chart. 

Here is the parameter below. Is there something I can change to sum each data set so that when I use this parameter for the Y cord it will change the data type and display totals for each date that is my X cord?
