Issue with label and value ranges in Bubble's chart plugin

Hi. I am using Bubble’s chart plugin (the free one) and I am having difficulty figuring out how to code labels (x axis) and values (y axis) to be more meaningful.

My chart should show 7 categories along the x-axis and currency values along the y-axis. There are 2 problems:

  1. The y-axis values seem to be automatically set to multiples of 1024.
  2. The x-axis categories ONLY appear in the chart if there is a value for it. This is not what I want, of course. I’d like to see all 7 categories even if some have no data yet.

I’ll post a pic here so you can see what I’m talking about. Is there a way to correct this? I’ve tried google charts but absolutely cannot figure them out and I’m not looking to pay for other plugins at this moment. Any thoughts?
