Mplfinance: Making the height of the candle shorter.

[toksis]

How can you make the candle shorter? Maybe making the distance of the Y axis like 1.045 TO 1.050 shorter? This happened when I magnified it to see details.

@toksis
I'm not quite sure what you are asking. The size of the candles depends the Open, Close, and High, Low in your data. Perhaps if you attach your data, and code, that was used to make this plot I may better understand what you are asking. Please also indicate what version of mplfinance you are using:

import mplfinance as mpf
print(mpf.__version__)

Thank you. --Daniel

On my magnified picture, the candle are so long that it will not fit the screen. On my link , you can adjust the size of the candle. You can do this to make the candle fit. Making the distance of the Y axis shorter like 1.05 to 1.10 is like 1 inch. Make it .5 inch?

Thank you.

Tell me if you will still need the whole code. Thanks.

class Chart:
    def __init__(self, df):
        self.df = df[1:]


    def boughtsoldplot(self,plotvalues):

    # Short = 0
    # Long = 1
    # End = 2
        buy_signal = []

        close_signal = []

        for x in plotvalues:


            if x == None:
                buy_signal.append(np.nan)
                close_signal.append(np.nan)

Thanks. I will try to take a closer look at this in the next couple of days. I now see what you mean from the link. It is really compressing the y-axis itself, and the candles just follow along. The code you posted should be enough, along with the data, for me to play with this and see what I can do get the appearance that you want.

[DanielGoldfarb]

1. Can you tell me what you used to zoom in?

2. Also, what backend are you using:

   import matplotlib
   print(matplotlib.get_backend())
   

   Please do the above import and print in the same file and at the same time (either just before or just after) you generate the mplfinance plot. Thank you. --Daniel

[toksis]

import matplotlib
print(matplotlib.get_backend())
None
TkAgg

This is the tool that went out after running the program. Thank you Daniel for the fast reply.

[AndySum]

I think this might be a matplotlib question, in which case you can select the Pan tool (the one to the left of the Magnifying Glass that you circled).

Then click and hold the right mouse button while you move the mouse down to vertically scale the y-axis (and candles).

Thank you!

@AndySum Thanks!
