how do I draw on line chart background color from bottom to value in Chart.js










0















I try to make line chart using Chart.js.



I think that when I draw positive numbers in my graph, background color draws very well.
using positive numbers



however, when I add negative numbers, the background color is upside like below.
upside down chart



I guess chart.js is based on zero value, but I don't know how to fix it. I want to start drawing background color from minimum number(in this chart -5 is the minimum number).



does anyone know about this issue when drawing some line chart?



Thanks in advance.
