I have a copy of Tee-Chart 5 (Delphi 5) and found myself to be stuck with the following problem: I want my cursor to follow the mouse and snap to a series of my line chart (which it does), but it should not react on vertical movements of the mouse, instead to horizontal movements only. So, when I move the mouse from left to right, the cursor should move, if I move the mouse up and down, it should stay where it is. I thought there has to be a way to calculate the coordinates of the series-point with the one horizontal value next to the horizontal value of the current mouse position. In other words... there has to be a way to find a proper series point with just the horizontal mouse position (granted, there is ONLY one possible point in my chart per horizontal or vertical position). In addition, I need the values of this particular series-point for some calculation while the mouse is moving. Uhm, confusing? I hope you can get my point... Actually, the F1-help is not helping much as I find all that calcXBlah calculates the value of whatever very confusing. So please, rescue my professional life and help me with this life-threating and hair-loss-causing problem! Any advice is greatly appreciated. Thank you a lot!

Setting the style to vertical makes the tool sensible to horizontal movements only. With ChartTool1 do begin Series:=Series1; Snap:=True; FollowMouse:=true; Style:=cssVertical; end; -- Best Regards, Narcís Calvet http://support.steema.com "Important note: If you are a TeeChart registered customer, please post your support questions at Steema's Support monitored Forums for customers: http://support.steema.com for a prompter reply."

This works, but shows only the vertical part of the cursor. I want the cursor to be a true cursor, with both a vertical and a horizontal axis, which only reacts on horizontal movements. Is there a possibility to... well... programmatically show the vertical line of the cursor through the point of intersection of series and horizontal cursor?
