The attached project contains an empty chart (no series added) that is
assigned to a ChartToolSet containing a DatapointCrosshairTool (no
changes in Shift property). When the mouse is moved into the Chart the
program crashes in TAChartUtils TPublishedIntegerSet.AsBooleans
because it tries to assign a value to result[0], although the dynamic
array "result" has been dimensioned to length AMax = 0 in case of the
empty chart.
