Hi All,

I am displaying historical data on a XYChart in Perspective. I created a dataSource using Tag History binding.

 ![TagHistoryBinding](https://us1.discourse-cdn.com/inductiveautomation/original/2X/2/23429ba43051b0f58734ea9364f103c0c4e27233.png)  
The start date and end date are from two DateTimeInput objects (props.formattedValues.datetime)

My problem is that the obtained data contains records outside of the specified time range. In particular, I selected end date as 2019-May-27, but data from May-31 still show up on the plot (Picture below). To verify this, I am displaying Unix time value for both DateTimeInput objects right below them. I can see that the last entry from the data table includes a time\_stamp after the end date.

Can somebody suggest what could be the cause here?

Thank you!
