Live
Displays a live window of one or more aligned indexed series. When data drops its oldest point and appends a new one, the line slides one step to the left, X-axis labels stay on their points and slide with them, and the Y axis rescales to the current window. Other changes that keep the number of points and series morph the line over shiftDuration; changes to either count redraw immediately.
The chart is display-only: it has no selection and ignores gestures.
shiftDuration is how long each new point takes to slide into place. Match it to how often data changes so each shift finishes as the next point arrives.
subtitle appears below the title and can also be shown on its own.
At least one series of at least two finite values is required. Negative values are supported. Series must have equal lengths. Categories may be empty; otherwise their count must match the values in each series. Invalid data renders validation errors in place of the chart.
