Trends - X/Y Axis Colors

Can you please fix this issue? First of all, the X-axis and Y-axis lines should be in different colors. Secondly, the colors shouldn't change from minute to minute, from the same color to different colors every time the user checks a trend! Too, for single nutrient, one-axis trends, I don't see why the left and right vertical bars should be in different colors!!! Or does the administration think those vertical bars should be in different colors, for single nutrient, one-axis trends???
