Mplfinance: How to number the candles?

[ismailbayram]

I would like to number the candles according to some indicators, but I do not know how to?

For example (TD Sequantial Indicator):

Ismail,

There are a couple of different ways to do this. First make sure you are familiar with mplfinance additional plot functionality.

• The simplest method is to use mpf.make_addplot(data,type=scatter) to make a scatter plot where the scatter markers are the numbers that you want. You can see examples of how to do this by clicking here.
  
  (Also, you can find several links for more information about custom scatter markers in this comment to issue 97).

• Alternatively you can use Axes.text(). This requires first that you gain access to mplfinance's Axes objects. After that, you can find an example in the following two comments:

  • example plot and
  • code to generate example plot

I hope that helps. All the best.

Thank you very much. This reply is very helpful.

@DanielGoldfarb the addplot / scatterplot is super easy to use, but unfortunately only for numbers under 10.
So, @ismailbayram in case you need a decimal point or 2 digits, you have to use the text() method.

@fxhuhn , Yes it gets trickier with 2 or more digit numbers, or with decimal. You can do it, for example setting scatter marker to $12$ or to $123$, however then the scatter marker may get smaller and you have to increase its size to make it more visible. At that point it may be just as easy to use text() which ultimately prints numbers more clearly anyway.
