Chart Renderer Line for smooth view

Hello I found a post (Chart cubic interpolation) that was giving tip for using renderer into chart but I got weird line with precision 15 and I try different and its not better. When I got 2 data that are the same value sometime its curving for no reason. Am putting the simple code that I use and share 2 picture. The script for now is on mouse press action

rom org.jfree.chart.renderer.xy import XYSplineRenderer

chart = event.source.chart
plot = chart.getXYPlot()

renderer = XYSplineRenderer()

# The Precision makes curve smooth ! You can play with changing the numbers.
