How To Use This Chart
Use the controls above the chart to switch temperature units, move between daily and rolling views, and toggle between radial and linear layouts. Hover anywhere on the main chart to move the date readout and update the lower panel for the selected water-year day.
Click year chips in the legend to turn individual years on or off. The lower chart mirrors that selection state so active years stay visually prominent while inactive years recede. Use the lower-panel label toggle if the value labels get too dense.
