Custom Data Into Labels

[ydragos]

Hi,
Thank you for a great library.
Can we add custom data into plot labels? I use outside signals data that I bring into the data frame like :Signal1:Long, Signal2:Short and when a few of them are in agreement I fire a trade. I would like to see the values of Signal1,Signal2 etc on the Labels in the graph.

I'm not sure what you mean by adding data into labels. Do you mean plotting externally provided signals, such as this?

def init(self):
    # Plot 'Signal1' column from the input dataframe
    self.I(lambda col: self.data.df[col], 'Signal1')

See also: #64.

right, but Signal1 is a string not numeric. I would just want to see it in the label for that day.

[ydragos]

so just wanted to see it the label that appears when you hover over a candlestick.

You might write an enhancement proposal about it on the issue tracker.

The only two current indicator plot types are line and scatter plot. I guess for categorical variables you could also do something along the lines of:

import pandas as pd

# Convert distinct labels in 'Signal1' to numbers
self.I(lambda col: pd.Categorical(self.data.df[col]).codes, 'Signal1')

If you'd like to work on "label" plot type for categoricals, PR welcome.

Thank you so much for your help. Let me see how far I can get with this and if more is needed I will reach out for PR details.
