<fpdoc-descriptions><package name="TAChartLazarusPkg"><module name="TAChartLiveView"><element name="TChartLiveView"><short><var>TChartLiveView</var> is a component optimized for displaying a long array of incoming data in a viewport with only the most recent data while older data are flowing to the left out of the vewport.</short><descr>The viewport is updated whenever the full extent of the associated chart changes. However, when property <var>Active</var> is set to <var>false</var> the viewport is fixed -- this is a setting which allows the user to review older data, or change the extent while still new data are coming at the same time.

<descr><p><var>lveAuto</var>: adjusts the height to the visible data range automatically. This works also when the chart contains several y axes. Ranges assigned to the axes (by setting <var>axis.Range.Min</var> and <var>axis.Range.UseMin</var>, and/or <var>axis.Range.Max</var> and <var>axis.Range.UseMax</var>) are respected (as long as data points are within this range).
