I want to plot my data with a coloured background, which need to be seen through the points. Therefore I want to have transparent lines.
I use a code similarly to this:
x=1:10
y=[10 29 38 7 6 4 83 7 29 10]
figure
p1=plot(x,y,'.')
p1.MarkerFaceAlpha=0.2
p1.MarkerEdgeAlpha=0.2
I get this error:
Unrecognized property 'MarkerFaceAlpha' for class 'matlab.graphics.chart.primitive.Line'.
Unrecognized property 'MarkerEdgeAlpha' for class 'matlab.graphics.chart.primitive.Line'.
Does anyone know how to deal with this?

It is because you’re trying to use the MarkerFaceAlpha property in Plot function, but this property is the part of scatter chart rather than plot function.
Just change the line
p1=plot(x,y,'.')
to
p1=scatter(x,y,'.')
And this should not produce any error
