I am making an Excel XYscatterplot chart using a VB program. I first plot two curves with point-to-point lines and no symbols in different colors. I then plot two curves with symbols only which are meant to highlight the values on the lined curves which my logic has chosen as "peak" point in the curves. This all works except that the last peak found does not get plotted with a symbol. I have checked my range of values and they are correct. Has anyone seen this also?
