Hi, 

After an upgrade to v3.5-1, the chart that shows measured data seems to have a display issue. To be more specific, the chart does not display all available ‘Latency’ data it has *when zoomed to 1 day* by mouse *click* on ‘1d’ above the chart (not by window dragging, which is below the chart).

For example, the following links show charts that display measurement data between two nodes (128.112.228.24 and 128.112.228.23). The query was made on March 9, 2016, at around *2:54 pm*.  However, when zoomed to *1 day*, the display cuts off at around 7:33 am. When zoomed to *3 day*, the data is displayed up to roughly 2:54pm. 

In other words, zooming to *1d* seems to cut off displayed latency data, even though the data *is* actually there.  Note that ‘Ping’ data is not cut off. 

Zoom: 1 day (1d)

* Zoomed to between 6am - 2:54pm by dragging the window with mouse, so that the difference between 1d and 3d is more obvious (i.e., 1d zoom is missing latency data)

Any help or insight would help!
