When using quiver() to plot arrows with directional components, a warning message and an error are being printed.

load('wind','x','y','u','v')
X = x(11:22,11:22,1);
Y = y(11:22,11:22,1);
U = u(11:22,11:22,1);
V = v(11:22,11:22,1);
quiver(X,Y,U,V)

fig2plotly(gcf, 'offline', false);

The previous code prints the following warning message:

Undefined function 'affine2d' for input arguments of type 'double'.
We had trouble parsing the quiver object.
This trace might not render properly.

And the following error:

Error using response_handler (line 31)
Hm... Plotly had some trouble decoding your 'args'. Are
you sure your data or styling object is in the right
format? Check out the examples at https://plotly.com/api
for guidance.

Overflow channel</a>.

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 untitled20 (line 11)
fig2plotly(gcf, 'offline', false);

Hi @gilbertogalvis,
Sorry but this still doesn't work for me using the current master. Could you check if it still works for you? Perhaps, a MATLAB version issue again!

Ok. I will test it again

can you share the test code here?

Sample code:

load wind
X = x(5:10,20:25,6:10);
Y = y(5:10,20:25,6:10);
U = u(5:10,20:25,6:10);
V = v(5:10,20:25,6:10);

quiver(X,Y,U,V);
pf = fig2plotly(gcf, 'offline', 1, 'open', 1);

PR #337 fix this issue in a more robust way

codes to test it:

load('wind','x','y','u','v')
X = x(11:22,11:22,1);
Y = y(11:22,11:22,1);
U = u(11:22,11:22,1);
V = v(11:22,11:22,1);
quiver(X,Y,U,V)

fig2plotly(gcf, 'offline', 0);

load wind
X = x(5:10,20:25,6:10);
Y = y(5:10,20:25,6:10);
U = u(5:10,20:25,6:10);
V = v(5:10,20:25,6:10);

quiver(X,Y,U,V);
pf = fig2plotly(gcf, 'offline', 0);

results looks as follow
