Formula in progressive monthly results cells is =SUMIF($D$2:$D$99,$D121,F$2:F100), changing as the months evolve. Therefore, where nothing has happened, return is nothing; I suppose, "zero". However, the line chart I'm using to visualize progression still displays the zero values; meaning after the last value above zero is charted, the next and succeeding values drop to and chart zero. How can I hide the zero charting until a positive value is posted in the source cells? Same question would apply to bar charts, as well. 'Preciate whatever you can do to help.
