Hi there,

The background grid is cached - so to update the number of grid lines you'll need to do this:

RGraph.cache = [];

Just before you redraw the chart.

Hi,

good solution, it helped me too, thanks.
Just 2 things:
- if the data is dynamically modified (using the .original.data), the cache clear has to be before that
- what about when you have multiple chart on your page, because it is a common clear, so it will effect all charts, right? Can I specified the cache clear?

regards,
Zsolt

Hi there,

> so it will effect all charts, right?

I would imagine so yes. But I doubt it will impact on performance too much.
