Setting the gridlines count to a fixed number for both left and right axes doesn't mean the gridlines will line up because gridlines don't necessarily land at the top and bottom of the chart. This is true even if you specify the viewWindow min and max, though the viewWindow bounds will be respected. The gridlines that are computed by the heuristics may determine that slightly better ticks result if it doesn't put a gridline at either extreme, or at both extremes.
We don't yet have a way of specifying the gridlines using an interval between gridlines together with a baseline value. That would provide a fairly straightforward solution, but until then, you should probably just use the explicit 'ticks' option, together with the viewWindow min and max. Regarding the 'flattening' of the chart, this is probably due to the baseline value of 0 being added to the chart, once the heuristics see that it is "close enough" to the rest of your data. I don't believe that just adding a second axis would cause that, since the axes are computed independently, so I expect you forgot about another change you had made. If you can provide a link to a page demonstrating what you saw, we can take a look. Hope that helps. On Mon, Aug 3, 2015 at 5:21 PM, Moustacheful <[email protected]> wrote: > Hello.
