polarplot() not supported

[xarico10]

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

theta = 0:0.01:2*pi;
rho = sin(2*theta).*cos(2*theta);
polarplot(theta,rho)

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)
response = makecall(args, origin,
structargs);

Error in plotlyfig/plotly (line 449)
                response =
                plotly(obj.data, args);

Error in fig2plotly (line 49)
p.plotly;

Error in untitled10 (line 6)
fig2plotly(gcf, 'offline', false);

PR #343 fix this issue #240.

to test it please use following code:

theta = 0:0.01:2*pi;
rho = sin(2*theta).*cos(2*theta);
polarplot(theta,rho)

fig2plotly(gcf, 'offline', 0, 'TreatAs', 'polarplot');

NOTE: it is necessary to use TreatAs Plot Option as 'polarplot'

results looks as follow
