I have a line chart showing % change over months; for the same value, I have lines that are not displaying horizontally in the chart and are implying a slight increase/decrease has occurred.
The percentages are a simple average of cells in a column. I've verified already that the cells contain the same whole #s (no decimal quantities used), so this is not a rounding issue. Here's a screenshot of the issue for reference:
Any ideas how I can fix this?
