Historical Trend time axis not updating

I have configured 5 Trend Views from each Data Log (to use different Y-Axis scale). But when I connect to PLC, the trend view Time Axis is not moving/updating. The data is getting stored/logged alright. I can manually update the time axis by toolbar button and the trend values are coming ok then. But automatic update of time axis is not happening. Please refer to attachment. Thanx in advance. Attachment Trend_TimeAxis_Problem.jpg (318 Downloads)
