Color variation not working using swarmchart

The input argument c isn't changing marker's color when using swarmchart().

rng(1)
x1 = ones(1,100);
x2 = 2 * ones(1,100);
x3 = 3 * ones(1,100);
y1 = 2 * randn(1,100);
y2 = [randn(1,50) randn(1,50) + 4];
y3 = 5 * randn(1,100) + 5;

swarmchart(x1,y1,'red')
hold on
swarmchart(x2,y2,'green')
swarmchart(x3,y3,'blue')
hold off

fig2plotly();

The previous code should plot 3 different series with 3 different marker's color (red, green and blue), however, they're all being plotted with the default plotly colors.

Expected and generated (https://chart-studio.plotly.com/~xarico10/329/#/) plot:

Examples on using the c input argument on swarmchart() can be found on:

首先运行包含三次 swarmchart() 调用和 fig2plotly() 的 MATLAB 示例；然后跟踪 swarmchart() 标记颜色的 fig2plotly() 转换入口点。当导出的 Plotly 图形保留 issue 中所示的红色、绿色和蓝色标记颜色时，即表示完成。
