When using pareto() there are multiple issues with the axes.

y = [90,75,30,60,5,40,40,5];
figure
pareto(y)

fig2plotly(gcf, 'offline', false);

Expected and generated () plots:

As seen, the x-axis edges are shorter, this produces the first and last bar to seem smaller and the distribution line to start where it shouldn't. Also, as the values are decreasingly ordered in the x-axis, the x-ticks aren't matching with those from MATLAB. Finally, the percentage ticks on the left side of the y-axis aren't there.
