Details

Before: What was the problem?

Doji means the open and close value of a data item is the same. Previously, it can either be borderColor or borderColor0 according to the previous data item. But if developers want to change it to a custom color, like a neutral colour like gary, it cannot be done.

After: How does it behave after the fixing?

So in this PR, we provide a new option borderColorDoji. If it is set, this color is used for all doji data items.

Looks great! I'm not famaliar with the term doji, should we also provide colorDoji?

[Ovilia]

@pissang Doji means the shape is like a cross (十) so there should be no filling color. So I believe colorDoji is not necessary. Thanks!
