I've been using combo charts for awhile to render scatter graphs of measured data, with line charts to represent user defined 'thresholds' (above which, the points are red flags). Rendering lines like this works, but the user can only hover over the end points to see its numeric value.
I like how the stepped area chart allows hovering over an entire section, and would like to use this instead. However, I do not see an option to make the area in question be 'above' the numeric values given. I could set options.vAxis.direction to -1, and although this flips the area, it also flips the numeric values of the y axis (and I need this on a combo chart with a normal scatter chart where up is higher y values). So I'm curious if there is an easy way to make the stepped area chart go above the line instead of below. Considering the framework can flip the entire graph, I'd think this would be relatively easy. Alternatively, is there an easy option for lines where the user can mouse over any point in the line and see its 'value'? Also, somewhat unrelated, but I had a set of data that was accidentally graphed where there were >400 thresholds (creating 400 very simple horizontal lines as separate series). When I render this in chrome, memory consumption grows and grows until chrome eventually kills the process. I'm surprised by this because 400 data points is very easy to graph. Is there a reason that 400 series each with 2 data points and a line between should be non-performant? Is there a better solution to prevent this, or do I simply need to add a limit to what I query from our database before rendering?
