I'm sure you'll do it - keep up the good work, my users love it.

Sadly I agree about performance - having looked at the code I see why. I would like to see much better performance - I'm sure Codejock can increase speed by at least an order of magnitude. Performance at the moment is horrible Cry but visually it's great Wink !]]> Wed, 27 Apr 2011 07:12:13 +0000 http://forum.codejock.com/forum_posts.asp?TID=18210&PID=64089&title=performance#64089 <![CDATA[Performance : I tried to add 10,000 points to...]]> http://forum.codejock.com/forum_posts.asp?TID=18210&PID=64086&title=performance#64086 Author: m.geri

I tried to add 10,000 points to the Fast Line sample with 5 lines  and it works quite well probably because the view range on X axis is 100 points.
Increasing the number of points of view range to 1000 painting and scrolling is very slow and graph that is obtained is not readable because the lines overlap with each other.
One solution could be to  be able to to set the maximum number of data points displayed at once. If the viewer, for example using zoom, selects a period that contains more data points than that this number, the chart groups data into longers periods using a "grouping" function (for example average).

You are right, and the changes you proposed did not do anything for the performance either. Adding and removing seems to just add and remove from an array, and this is ok fast.
The problem is the drawing or rendering:
 
Enabling the performance counter already added in XTPChartControl gives the following result
CXTPChartControl::OnPaint: 150957246
for 3 CXTPChartFastLineSeriesStyle series with 10000 samples each.
 
Which gives approx. 10.5 sec. !

I wouldn't have thought RemoveAll would be that expensive.  Have you tried tracing tick counts to see how long it even takes?]]> Tue, 26 Apr 2011 07:29:24 +0000 http://forum.codejock.com/forum_posts.asp?TID=18210&PID=64075&title=performance#64075 <![CDATA[Performance : Can I do anything to replace the...]]> http://forum.codejock.com/forum_posts.asp?TID=18210&PID=64074&title=performance#64074 Author: cpede

Can I do anything to replace the pPoints->RemoveAll() call, if I know that I just need to fill it up again? Maybe with less points?

there are several things you could do perhaps to speed up your loop.

1. Don't call m_pSeries->GetPoints() each loop, cache the result
2.Tell the array how many points beforehand (CArray::SetSize()) so it doesn't need to do 20000 reallocs

Cheers

Well, looking at the .NET-like object way CodeJock has implemented it you are right.
 
But I must say that I'm  actually very disappointed. I', using C++/MFC because of the performance. I have a lot of colleagues writing C#/.NET code and every time I can out-perform regarding performance and efficiency. And thanks to CodeJock I can also make GUI code just as fast as they can. When CodeJock then comes out with a chart control I was actually expecting performance, but what we got was just another slow chart component,  probably good for financial charts with up to 100 samples. You can find a trillion of these kind of component on the Internet, good looking but with bad performance. I will go back to ComponentOne Chart until CodeJock at least comes
close to that performance.
