CPU usage of Real Time Charts

Question

Dear Sir/Madam:I have a question regarding the CPU usage of the Chart Controls.In Essential Studion v7.2.0.37 for Windows Forms, I tested the Chart Samples ==> Real Time ==> Chart Recorder.I launched the sample directly from RUN SAMPLE.  Once I unchecked the Scrolling checkbox and waited for 5 minutes,Over 50% of the CPU was used by the application.   (It’s similar for Chart Samples ==> Real Time ==> Chart Real Time.)Is this normal?  Is there a way to reduce the CPU usage?Attached is some screen shots.Thanks!Xu ShiChartRealTime_CPU_Usage_f0dd31c6.doc

Hi Xu Shi,Thanks for your interest in Syncfusion products.In the given sample, interval property of timer is set to very lowest value (200 milliseconds). When we set this value to a considerable time interval (800 milliseconds), then CPU usage will be decreased.We are also having properties and methods to improve the Chart Performance when very large amount of points are loaded in the Chart.Refer the following link for further details.http://help.syncfusion.com/ug_72/chartwin/ImprovingPerformance.htmlPlease let me know if you have any other concerns.Regard,Venkat.
