dc.js x axis ordinal chart issue

问题

I am trying to draw a simple bar chart using crossfilter, dc.js and angular-dc. The piechart works fine. The barchart does not render the bars. In Chrome, if I inspect, I see the values are there. and if I force focus, I do see the charts. I have tried all the suggestions but it seems that there are 3 issues:

Bars are starting at 0
The width is 1 px
Bars are not rendering on the screen

Any pointers?

Here is the code:

I could not find a solution to this problem But another way of integrating the dc and angular which we did was to feed data to the crossfilter via the angular scope and code the charts as we do normally in dc and set them up in the html by calling divs. We did not notice any performance downgrade using this method.
