You can categorize numeric values inside the chart. See Category(Binning) for the detail.
You can use Limit Values to filter the categories by the aggregated values. See Limit Values for the detail.

Number of Equally Spaced Points - How many data points used to draw the line. If you assign a larger number, the curve will be smoother.
