A HiLo series draws a vertical line between a high and low value for each date, providing a compact way to visualize data ranges such as price spreads or temperature extremes.
This sample uses weather CSV data to plot daily minimum and maximum temperatures as HiLo segments. Major and minor Y-grid lines improve readability, custom HTML tooltips display values with degree formatting, and range picker/selector controls enable fast date-window navigation.
See the AnyStock Series documentation for all configuration options.
