In the previous release of the Tchart, this tool worked properly. As long as I widely use this function, it would be great if you could rapidly fix this bug.
You can even verify this abnormal behavior through the “Tee9New_win64Delphi23.exe” demonstration application. If you search “LegendScrollBar”, then select and run the last proposition also called “LegendScrollBar” and finally, move the slider in the legend, the graph vanish.
