[xarico10]

When using polarscatter() to plot a scatter plot in polar coordinates, an error is being printed.

th = pi/4:pi/4:2*pi;
r = [19 6 12 18 16 11 15 15];
polarscatter(th,r)

fig2plotly(gcf, 'offline', false);

The previous code prints the following error:

Error using response_handler (line 31)
Expecting (x, y) pairs

Error in makecall (line 32)
    response_handler(resp);

Error in plotly (line 28)

structargs);

                response =
