This is a nice example of how customer feedback can make Slope better, even in small but important ways. Recently some folks who use mobile devices have been complaining that the symbol is too hard to make out. Until now, there have been a couple of “watermark” choices in SlopeCharts which you could choose if you wanted to augment the center of the chart. You could put in the SlopeCharts logo or the corporate logo, like this:
Now, however, I’ve added a third watermark (accessible via the Preferences in SlopeCharts) which puts a nice big ticker symbol right in the middle. This should address the complaints I’ve been getting so that even iPhone users can see what charts is being discussed.
