TeeChart for .NET v2021 Performance issue with histogram

Post by » Tue Feb 08, 2022 3:26 pm

Hi Team,

Used DLL = TeeChart.WPF
Version = 4.2021.7.22
I need help to improve the performance on point data source assignment with histogram function.

I have created a Histogram Points chart with sample inputs of 308,163.
To perform this , I have created a FastLine series and assigned all samples to it. Then using this FastLine series as datasource to Points series with Histogram function.

I also have attached the sample project, while debug you will observe in method MainWindow(), code "series2.Function = hist;"(Line number 15) takes more than 2 min to get executed.


Regards,
Pritosh

Okay, we've got your example down to loading in less than half a second. There are some techniques we can use in our production code here, and which we will add to it for the upcoming release.
