Hi,
Please try to add the following CSS block at the top of the page:
Code: HTML/ASPX
<style type="text/css">
text
{
fill: #000000;
}
</style>
The problem is caused by the fact that NVD3.js did not explicitly set the fill color for its text element. It seems that in our code the default fill color is transparent (which makes sense for shapes such as rectangle, but does not make sense to text). The above code explicitly set the text fill color as black. Once the text fill color is set, you should see all the text.
Hope this helps. Please feel free to let us know if you still have any questions. We will also look further to see if we can change the default fill color for text element.
Thanks!
