Hi guys i hope you can help me with this

i followed this link :

> [How to chart/graph from stored text files to the chart](https://discourse.nodered.org/t/how-to-chart-graph-from-stored-text-files-to-the-chart/1803)

to make a chart from my stored data. The only thing is that i have 3 decimals.  
My data file contains these values:  
_1567202580002 - 0.076_  
_1567288980003 - 0.393_  
My chart shows only 0 's . They are rounded. That's not what i want. I want to see the 3 decimals in my chart.  
I allready know that this function will round up my values ( the second line):

> var parts = msg.payload.split(/ - /).map(function(v) { return parseInt(v)});  
> **msg.payload = {x:parts[0], y:parts[1]};**  
> return msg;

can you please help me out here  
!!!!!! Many many thanks in advance !!!!!!

here is my export
