Materialdesign: chart-bell-curve-cumulative

[jacobq]

Similar to #3697 (:heart:) I would like a chart icon resembling a cumulative distribution function or at least one that never decreases.
Perhaps it could look something like this:

I would like to use this to identify a "plot cumulative" option vs. a "plot" option. Alternatively, having a chart icon with a capital sigma or plus sign on it might also work.

Perhaps a more clear way to express this would be to show 2 traces on the plot, one dotted or dashed -- perhaps following the shape of the one in mdi-chart-line -- and then another which indicates the integral of that trace (e.g. if the first function is constant then it is linear, if the first function is linear then it is quadratic, etc.). The challenge with this approach is keeping it clear that we're talking about two traces/function, not, say, a function and a threshold / cursor.

Maybe we could alias this as "sigmoid". I know it's different from cumulative normal distribution, but sigmoid functions are commonly used in neural network programming, and also is strictly increasing.

Maybe we could alias this as "sigmoid".

That's fine with me. However, for that case it might be better to draw the vertical axis through the middle instead of on the left. (But I still want it on the left for this one.)
