Hi, I used this example to plot my dataset in a smith chart: https://www.mathworks.com/matlabcentral/answers/310051-how-to-plot-smith-chart

My problem is that is nearly impossible to handle the figure properties. For example:

x=[0.1 0.3 0.2]; 
y=[0.3 0.5 0.2]; 
smithchart; 
hold on; 
scatter(x,y,'o','r','filled');

The plot shows what I want. No problem. Now, I want to configure the figure properties, plot size and position and so on.. But it seems that the "smithchart" function creates an own figure or something like that. If i try this code:

x=[0.1 0.3 0.2]; 
y=[0.3 0.5 0.2]; 
fig = figure; 
set(fig,'units','normalized','outerposition',[0 0 1 1]); 
set(fig,'Name', 'Test','NumberTitle', 'off'); 
smithchart; 
hold on; 
scatter(x,y,'o','r','filled');

The change of Name and Number of the figure doesn't work. I have to move the "smithchart"-command between the two figure-set commands. I know that "smithchart" is more a function than a plot command.. But anybody have an idea, how i can plot my files in a smith chart without having trouble at changing the plot properties?

Best regards
