Improvement: Single error message

Hi

We have a client using your plugin (which is great by the way!) to display results from surveys created in Gravity Forms. When a new survey is created its added to a page template which creates a display for both the survey and its results at the same time. So until someone actually responds to the survey, there is nothing in the graph to display. In this case, we get an error message displayed:

No answers yet to field number 1 : [question title]

But we get one of the above errors for each field (4 of them in our case), so it looks quite messy.

It would be great to replace this with a single message, something like (there are no submissions yet) or, even better, a way of adding an option to the shortcode to control this. e.g.

[.. no-results-error=”There are no results yet”]

Thanks
