• The data for this site and selected datastream at this link doesn't display if you are trying to view more than 5 years of data at a time.

• For this site the sub-daily doesn't display, but the daily does (only the line shows) none of the points are there and values don't pop up when you hover over the plot.

Expected Behavior

All the data and points should be viewable at any time range.

Actual Behavior

Data does not display if there is too much over the time span.

Any additional comments?

@alexheilig It looks like the this is happening because the both datastreams' time interval changes over time and isn't consistent. In the second one for example, the datastream contains both hourly data and 15 minute data, and since the intended time spacing is declared as 15 minutes, the chart sees the hourly data as having a gap between every value.

@daniel-slaugh Do you know if these issues would be fixed by moving over to the newer plotting used by the QC app? It seems like there's other plot display issues that pop up when the actual time spacing is variable or doesn't align with the intended time spacing. Is there any way to have the individual points always be visible regardless of the time spacing, but only connect the points who are spaced either equal to or more densely than the intended time spacing? Basically we'd just treat the intended time spacing as the maximum gap over which we'd connect two points, but not as a required spacing for the data.
