Hello Gentlemen,  
May I know if it is possible to make our Dashboard Chart having different YAxis per topic?  
I have 2 topics that has a big difference on the values, and my chart doesn't look good for that. That is why I am asking if possible to make two YAxis for each topic?.

Thanks !  
Regards

not with the simple charting we have available no.  
Either rescale of your number ranges to something more equivalent (can you use milli... or kilo... ?) or you will need to use a ui\_template and a different charting package.

Thanks for the prompt answer and insights Sir. Hopefully in the near future we could have this options in our Dashboard Charts.

It is possible to create left and right axes  
[https://www.chartjs.org/docs/latest/axes/cartesian/#creating-multiple-axes](https://www.chartjs.org/docs/latest/axes/cartesian/#creating-multiple-axes).

```auto
msg.ui_control = {options: {
        scales: {
            yAxes: [{
               
                id: 'left-y-axis',
                type: 'linear',
                position: 'left',
                ticks: {
                    suggestedMin: 0,
                    suggestedMax: 1000
                }
            } , {
                id: 'right-y-axis',
                type: 'linear',
                position: 'right',
                ticks: {
                    suggestedMin: 0,
                    suggestedMax: 10
                }
            }]
        }
    }
    
}
delete msg.payload
return msg;

```

But I'm not sure if live data can be managed to follow the configuration. Probably not.
