Bar graph is NOT using all its allocated space, anyone now why?

[Daniel-PNW]

Anyone have found that bar graph uses only like 3/4 of the allocated layout area - no matter how large or small you make the area? I cannot figure out why when if you use the line graph, it uses 100% of the same allocated area. See red arrow in screen shot below.

Again, if I change the exact data to line graph, it WILL fill up the container completely. Strange indeed! Thanks if anyone has any ideas or pointers.

I think it's the Responsive Design feature that's responsible for this. If the bars are a certain width then they won't be made bigger and spread over the x-axis when you give the chart more space on the canvas.

Any solution though?

Normally, I'd think bars would stay that size while white space between just increases. That would seem logical first step in building such a responsive design.

Thanks for thinking about it and letting me know.
