Charts - Horizontal Lines Not Bold Enough
Going to Trends, then Charts, the horizontal lines aren't dark enough. Ever get a supermarket receipt where the store didn't replace the ink in the printer and you could hardly see how much you paid for the products that you purchased? The datapoints that are graphed on the charts are referenced by faint, off-white horizontal lines on a white background that go from the left side to the right side using reference points on the left side: 1,000 calories, 2,000 calories.... Without a stark, dark, horizontal line on the graph to allow the eyes to track from left to right, the visual feedback isn't what it could be.
I have an app that allows me to change the fonts on a webpage in a thousand and one ways, that also allows making the text bolder, but that app does nothing for these horizontal lines!
