Bug when changing series type?

I think I might have found a bug.

In our app the amount of data points range from 50 to 200 000+ and the chart never bucks under it. Performance is understandably "not super fast" with 200 000 data points, but acceptable.

But when changing type from (fast)line to bar, the component hangs, it doesn't responds again. I thought this might be with data in the range of 200 000+ data points, but I just tested changing the type of a series with 150 000 points with no hickups.

So what is the difference between these two sets of data? Well, one contains null values and one doesn't. So what I have is one chart where I can change series typ and one where it's not possible - with null values in the dataset.

Just something to look into I thought.

Cheers,
Tommie

Hi Tommie,

Series styles not being FastLine are not designed to be used with such an ammount of data. They wouldn't even look good on the screen. Even though, could you please send us an example, with data sets like the one you described, we can run "as-is" to reproduce that behaviour here?

Thanks in adance.
