pcolor(X,Y,C) not working correctly

[xarico10]

When using pcolor(X,Y,C) specifiy the x- and y-coordinates for the vertices of values in matrix C, a completely different plot is being created from expected.

X = [1 2 3; 1 2 3; 1 2 3];
Y = X';
C = [3 4 5; 1 2 5; 5 5 5];
pcolor(X,Y,C)

fig2plotly(gcf, 'offline', false);

Expected and generated (https://chart-studio.plotly.com/~xarico10/789/#/) plots:

PR #341 fix this issue. This issue is related to pcolor similar to issue #265. Then working with this issue I was careful to ensure that modifications works for both issues (both #263 and for #265)

codes to test:

X = [.5 2 6; .5 2 6; .5 2 6];
Y = X';
C = [3 4 5; 1 2 5; 5 5 5];
pcolor(X,Y,C)

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

[X,Y] = meshgrid(-3:6/17:3);
XX = 2*X.*Y;
YY = X.^2 - Y.^2;
colorscale = [1:18; 18:-1:1];
C = repmat(colorscale,9,1);
pcolor(XX,YY,C);

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

Here the results

Also, as suggested @VolKa79 in the review of PR #340. I have removed the x and y axis titles
