Bug stacked bar

[ybarbaria]

Description
I noticed this bug [I think it would be a BUG], when I set line bar stacked with only one element and it's data = [-25.6], the chartjs draw only one bar horizontally extended.

Expected Behavior
Bar stacked to the bottom

Current Behavior
The bar is extended horizontally.

Possible Solution
I fix this bug in my code by setted the data with empty values.. data = [-25.6,,,,]

Steps to Reproduce (for bugs)

Configuration of the dataset=>

backgroundColor:"#f57f17"
borderWidth:1
data:[-25.6]
label:"Order Sell"
type:"bar"
yAxisID:"y-axis-0"

Configuration of the y axes =>

 gridLines: {
        display: true     }

Configuration of the x axe =>

stacked:true
    gridLines: {
        display: true, 
        offsetGridLines: true
     }

Environment
Chartjs 2.6.0/2.7.0/2.7.1
Version 63.0.3239.132
Windows 10 64bit

This is fixed in master (#4994) and will be release in 2.8. You can verify that it works with https://rawgit.com/chartjs/chartjs.github.io/master/dist/master/Chart.min.js

Thx @simonbrunel !

I have this same issue:

The suggested new version that will be in 2.8 has helped a lot, but still has some bugs:

You can probably see here that some of them float, and some of them seem to be flying off into the ether. The one in the very top right has a value of 17, so should be at the bottom, not filling the full vertical space.

Still, I'm so so very relieved to see there's something that at least 95% fixes this issue 👯

@simonbrunel When is 2.8 scheduled for release, may I ask? I never really know where to look or who to ask for this kind of information.

Just looked into it a bit more, and it seems it's still having issues somewhat:

It starts off well, but then something (and I'm not sure what) makes it go a bit odd and do big wide floating bars.

Ps. This is when it's as "linear" distribution. The issues aren't quite as noticeable when it's "series".

Okay, thanks.

Another quick screenshot showing far more data and how mangled it looks:

Edit: Discovered why it was coming out so funkily. Turns out that all the data needs to be padded with zeroes in order to get it to work. This is a separate issue entirely though (#5072)

@ybarbaria you didn't confirm that this issue was fixed? I will close it for now per my last comment but feel free to reopen if you still experience this bug in the latest version.
