Divide By Zero In Scatter Plot With All Points Y Value Below Zero

[kevinkey]

In the version 1.5.9, I've found there are a few places with "/(this.chartLines-1)", which can result in a divide by zero. It was happening to me when I had a scatter plot with a set of points all less than zero. I simply did a find and replace for that string with "/Math.max(1, this.chartLines-1)". It fixed my problem, but I'm not 100% sure that that is the best solution. Perhaps the expression shouldn't be "/(this.chartLines-1)", and should be "/(this.chartLines)", which would have also prevented the divide by zero.
