Power Apps ColumnChart improvments needed

I have this SharePoint list, which stores the following info:-

 

Mainly TotalNumberOfCompletedWorkOrder & TotalNumberOfWorkOrders. and i am showing those columns inside a Column chart inside my canvas app, as follow:-

 

But i need to know if i can do those 2 improvements:-

 

1) To show the percentages of the TotalNumberOfCompletedWorkOrder ? so let say i have those numbers for a chart:-

 - TotalNumberOfWorkOrders =375

 - TotalNumberOfCompletedWorkOrders = 25

 

To show 6% beside the 25 ? something as follow:-

 

2) To fix the relative height of the columns to really represents the differences, for example this seems confusing:-

 

so in the second chart i would assume that the "5" column height should be 1/2 the height of the "11".. while in the above charts seems the layout is a bit confusing... 

 

Please any one can advice if there is a direct or any workarounds to fix the above 2 issues?

 

Thanks
