This would be an awesome feature!

[jackled]

Yes, absolutely. Any idea when this is coming? The research project I'm working on requires background reference lines in bar graphs. I'm certain that this feature would make a number of people very happy.

I implemented this feature locally a while ago, because I needed it so much, I can do a PR with these modifications

@AlisonVilela I would love to see a PR for this, or just your implementation would also be very helpful! Thanks in advance

any updates on this?

@AlisonVilela can you please post your solution?

@AlisonVilela would you mind sharing your implementation ?

I faced the same issue. My solution might not be the cleanest but it worked. You can create a new component and copy the ngx-bar-chart component from the ngx-charts-Module into it.
Then add the following 3 lines to the ngx-charts-y-axis:

[referenceLines]="referenceLines"
[showRefLines]="showRefLines"  
[showRefLabels]="showRefLabels"

Thanks kolya-kra I just did this with stacked bar chart and works like a charm. If somebody need it I can send more info.
