Null bitmap for chaquopy-matplotlib project while displaying in imageview

[sushmasrinivas57]

I am creating a project similar to chaquopy-matplotlib. Bitmap is null while image is getting displayed from the byte array returned from python script

 val bytes = module.callAttr("plot",
                                            findViewById<EditText>(R.id.etX).text.toString(),
                                            findViewById<EditText>(R.id.etY).text.toString())
                    .toJava(ByteArray::class.java)
                val bitmap = BitmapFactory.decodeByteArray(bytes, 0, bytes.size)
                findViewById<ImageView>(R.id.imageView).setImageBitmap(bitmap)

import io
import matplotlib.pyplot as plt

def plot(x, y):
    xa = [float(word) for word in x.split()]
    ya = [float(word) for word in y.split()]

    fig, ax = plt.subplots()
    ax.plot(xa, ya)

    f = io.BytesIO()
    plt.savefig(f, format="png")
    return f.getvalue()
