Hi PALLINI,
Thanks for your interest in Syncfusion product.
I have created a simple sample such that series1 adds 9000 datapoints and series 2 adds 5 datapoints such that 1 item per year.
The column Chart type is rendered such that on increasing the number of dataPoints the width of the column decreases.
I have attached the sample, please refer to the sample and let me know if it helps.
Regards,
