Does anyone know of a charting package that supports either of the following trendline drawing aids: - while dragging out the trendline, the angle of the line (from horizontal) is displayed. - while dragging with the "shift" key (or somesuch) pressed, the line is restricted to a angular step-size -- I know some do this for steps of 45 degrees only, but I would need the step-size to be user-definable. If no stock-chart programs support this, I would even settle for a graphics program which I can import chart images to. Thanks
