The trends on the very right side of the easy chart cannot be plotted, there was a blank space all the time. Does anyone have the same problem? thanks.

What time was it when the screen grab was taken? What is the historical scan class of the tags being charted?

Is your client datetime in sync with the gateway's datetime?

I've never seen the chart problem when this **wasn't** the cause.

The client EasyChart is requesting data to plot from the "now" minus X to "now", based on its own clock. If that clock is five minutes behind the gateway clock, then there will be five minutes missing.
