Displaying Data in Trend at Wrong Time

[abdullah123456789]

Hello,

I'm having a problem with the Historic List and Trend display of the signal in Geoscada Expert 2021. Using the Calculation Tag from the data I received hourly during the day, I made it save the Historic List as only 1 data per day, and the Historic List saves it at 12 a.m. every day. I am sharing the data I have obtained in the last week as follows.

But when I create a trend and add the signal for which I calculate, I cannot display it exactly as I want. 12 a.m. to the current day. The data saved in the watch will be displayed on the trend until the next day. But when I view it in trend, the data recorded at 12 a.m. is shown starting at 12 p.m. and covering 12 p.m. the next day. I present what I am talking about in the image below. The top image is the Trend page I'm currently viewing. In the image below, I have shown the way I want to display in addition to the current page. Incorrect notation covering 12p.m.-12.p.m, which is dark blue and solid; the yellow and hollow one is 12 a.m.-12 a.m. display in the format I want, covering between

I also share some of the settings I made regarding the signal on the trend page.

The "Filled Bar" style of trace centres the bar over each value - the position of the markers highlight this (they are very small in the screenshots above). This means that for a 24 hour wide bar with a value at midnight the bar will span from midday to midday as you observed.

You could try using the "Step First" style of trace, but this isn't a filled bar.

You could try using the "X Offset" on the trace's source to add or subtract 12 hours.

NB. This trend has a processed historic trace using the "Start" algorithm which doesn't make sense given the calculation point has already done the required processing to give daily values, additional processing should not be required in the trend.
