pie3() rendering problems

[xarico10]

When using pie3() to plot a 3-D pie chart, huge rendering and visual issues are happening.

x = [1,3,0.5,2.5,2];
figure
pie3(x)

Expected and generated (https://chart-studio.plotly.com/~xarico10/511/#/) plots:

As seen, there are plenty of issues: chart's height is way too much, the grid is being plotted (when it shouldn't) and a 2-D pie chart seems to being plotted under the 3-D chart.

Examples on using pie3() can be found on:

At jack's request, today I was working on issue #199

PR #335 fix this issue

To test it, please run following code

close all, clc

x = [1,3,0.5,2.5,2];
figure
pie3(x)

fig2plotly(gcf, 'offline', false, 'TreatAs', 'pie3');

result looks as follow
