Would be nice if the historical data contains TWO lines: the actual numbers and the predicted numbers.
It basically does. Its split down the middle, past numbers are -30 through 0, future numbers are 0 through 30.
Yes but what I'm saying is, to the RIGHT of the 0, we should see only one line (the prediction) whereas to the LEFT of the 0, we should see two lines (two colors) with one color showing the historical data for each data point while the other color shows what the prediction had been for that same data point.
That we can can see not only the historical data, and the prediction data, but we can see HOW THE prediction data measured up against the historical data WITHOUT having to compare to other images or data sets.
Yeah, but that would require me to record the prediction which requires more code than I've really wanted to put in it.
In addition, what would I record? Merely the next day? The whole 30 days is a complete prediction, so it may get the exact days wrong, but it'll get the general shape over the next 30 days right give or take. So, what you really want is for me to just allow you to predict the past on demand.
