Zoom responding too slow with large data #52

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
I have around 2000 records which need to be plotted at a time.
It works fine.
But whenever I zoom a particular area, it takes nearly 5 mins to zoom that 
area. Mostly it stops responding.

Is there anything needs to be configured to get it working fine?

I am using JSF 2.0.2, primefaces 3.4.2 and wicked charts 1.5

Hi,

can you please provide an Options class that contains the configuration of your 
chart (or something close). Just subclass the Options class and add all your 
configuration in the constructor. With this class, I can run some tests to 
check what's the problem.

Regards,
Tom

Hi Tom,
Is it possible to resolve this issue on high priority?

Your test class doesn't really help since it references a class I don't have 
(YAxisVO) and it does not say anything about the number of axes and data points 
you added, since the method getSelAxisList() is missing. 

Anyway, I probably cannot do anything about the slow performance since the 
underlying javascript library (Highcharts) probably just does not work with 
your data. Perhaps you should ask in the Highcharts community.

Hi Tom,

Actually YAxisVo class consists of color of axis and name of axis.

The number of axes is not fixed. User has the liberty to select the number of 
axes. Also the data points are all dynamic as the data is coming from database. 
There will be around 43000 data points.

Anyway, I just wanted to know whether I am missing something because of which 
the zooming is slow. Thanks for your reply. I will ask this question in 
Highcharts community.
