This didn't happen the first time I move the slider around, but it seemed that a combination of checking/unchecking parameters and moving the data slider caused this bug.

Also, when I go back to the map view, using the back button, and then enter the detail view for the same location, it defaults back to the erroneous chart display. It also seemed to get stuck there and I could not correct it by checking /unchecking parameters or by moving the date range slider.

Screenshot is attached.
