Clarification: I originally tried to use TChart1.axis.left.position. The problem was that when I added values to the series (which changed the width of the axis labels) and immediately tested .position it did not reflect the new width. I moved my resizing code to the AfterDraw event and all is well....

How can you obtain the X-value of the left side of the frame (or bottom axis) relative to the left side of the TChart control?

Need to keep a slider-like control aligned with the actual start of the plot when the size of the left axis changes.
