Legend does not resize to text content

[ymk00]

I have a dynamic legend and am trying to have it resize to fit the text content. However, right now the legend will expand but not contract.

Here is a basic example:

import finplot as fplt
import yfinance
import numpy as np

df = yfinance.download("ASTS", interval="1d")
df["Date"] = df.index.astype(np.int64)

ax = fplt.create_plot("ASTS")
legend = fplt.add_legend("", ax=ax)

df[["Open", "Close", "High", "Low"]].plot(ax=ax, kind="candle")

def update_legend_text(x, y):
    row = df.loc[df["Date"] == x].iloc[0]
    legend.setText(f'<span style="color: white;">O: {row["Open"]:.2f} C: {row["Close"]:.2f} H: {row["High"]:.2f} L: {row["Low"]:.2f}</span>')

fplt.set_mouse_callback(update_legend_text, ax=ax, when="hover")
fplt.show()

You can see how the legend will grow larger to accommodate longer text but will not shrink back when going to shorter text.

Unfortunately I don't know, you'll have to look into the pyqtgraph code for how legends are made to find a solution. GL!
