FileNotFoundError: [WinError 2] The system cannot find the file specified

When trying to run the first example in the readme,

import asciiplotlib as apl
import numpy

x = numpy.linspace(0, 2 * numpy.pi, 10)
y = numpy.sin(x)

fig = apl.figure()
fig.plot(x, y, label="data", width=50, height=15)
fig.show()

I get the following error;

Traceback (most recent call last):

I'm using Python 3.6 on Windows 10 64-bit.

Looks like you don't have gnuplot installed.

I'm an idiot - didn't see the bit in the readme saying I needed gnuplot installed. Works fine now :)

B.t.w. - thanks for the awesome library!

I have gnuplot verison 5.4 installed, and I am using python 3.9 on Windows 10 64-bit version.

But I am still facing an error, similar above:

Do you have any idea what I am missing?

[nschloe]

termplotlib needs to find gnuplot, and it looks like it has problems doing so. Perhaps gnuplot isn't in your path?

[Marikson]

You were right! I was not precise enough, when i was installing gnuplot. Just needed to add gnuplot to PATH.

Here is the hint to scroll down to see further install options.
