To achieve below effect, mainly is the Y axis of the format, the x axis as the time, in the Y axis x to the normal range, such as 20, such as volatility is 0.5, sd is 20.5 1, 2 sd is 21, so on,
The current problem, integral is not much, hope to give some directions;
1, Y axis itself for various values, how to present the effect of the
2, the X axis is date, on this, how to present the effect;



Now to reach the effect of:







The background code:
