update-chart-widget

Arguments: chart-or-plot &key update-now

This function recomputes the value range of a chart-or-plot and invalidates so that it is redrawn with the new value range. The return value is undefined.

Normally this would be needed only if existing values in a chart or plot have been changed to smaller values that would fit into a smaller range. Other modifications to the chart should update the chart automatically, including when a new value lies outside the current value range, but this special case would be inefficient to check for.

This function would have no effect if you have specified true values for both the range-bottom and range-top properties of the value axis, since the value range is never autocomputed in that case.

See chart-widget, plot-widget, and also cg-chart-widget.htm.
