docs - boundedline

these do plot, however they return an error - https://github.com/plotly/plotly.matlab-docs/blob/main/matlab/2021-08-04-continuous-error-bars.md

The error I received when I ran it first time was:

Error using matlab.graphics.illustration.Legend/get
Unrecognized property Legend for class Legend.

Error in
findLegendAxis>@(x)(isequal(handle(get(x.Handle,'Legend')),legendHandle))
(line 5)
    legendAxisIndex =
    find(arrayfun(@(x)(isequal(handle(get(x.Handle,'Legend')),legendHandle)),obj.State.Axis),
    1);

Error in findLegendAxis (line 5)
    legendAxisIndex =
    find(arrayfun(@(x)(isequal(handle(get(x.Handle,'Legend')),legendHandle)),obj.State.Axis),
    1);

Error in plotlyfig/update (line 742)
                legendAxis = findLegendAxis(obj, handle(legs(g)));

Error in plotlyfig (line 296)
                obj.update;

Error in fig2plotly (line 44)
p = plotlyfig(varargin{:});

Error in test (line 7)
fig2plotly(gcf);

It prevents the plots from plotting in the docs, hopefully it is reproducable.

首先运行 matlab/2021-08-04-continuous-error-bars.md 中链接的示例，并将该失败与报告的 stack trace 进行比较。阅读所示位置的 findLegendAxis、plotlyfig/update 和 fig2plotly；完成的标准是确定需要修正示例还是绘图路径，并验证文档中的 plot 能够在没有此错误的情况下渲染。
