"Smoothed Line" Chart messing up curves

[GeroSalas]

I'm following your docs at: https://www.amcharts.com/docs/v3/reference/amgraph/#type_property and https://www.amcharts.com/docs/v4/chart-types/xy-chart/#Smoothed_lines to get a "smoothed line chart" correctly, but it seems something is wrong internally at the library since it is messing up the curves and it looks really bad.

(EXPECTED) I'm trying to get something like this:

(ACTUAL) but I'm getting this:

Here I shared a JSFiddle to check my code.

What is going on here?

NOTE: I'm using amCharts v3

As mentioned in your SO post, try setting equalSpacing to true in the categoryAxis object to work around this.

cool! thanks @xorspark! that seems to work on a single chart very well... buut when I tried that on a multiple chart with many lines plotted it still getting messed up :/ look at this (pay attention to the "pink" line):

any ideas here?

Assuming you're using equalSpacing, your data is sorted and grouped in ascending order, and the minPeriod is set correctly, there's not much else to suggest outside of not using smoothedLine in v3 or moving to v4 where this works correctly.
