´Charts not showing all data points

Dear Developers,

 

I am reading an ASCII file at every 200 msec. The data point history shows all the measured points (i.e. 5 measurements every second at the rate of 100 msec per update). However the chart only shows 2 data points each second. Is it possible to plot all the data points i.e. each 200 msec update. I dont know how to attach a snapshop here but if someone is willing to help me out then i can provide the snapshots. 

 

Best Regards,

Almas
