I am using fnplt to fit curve to my data. My difficulty is to control marker instances and style on the attached graph. I want all marker instances match given instances on the shown Polar Angle axis. Markers need to be a bit bigger and filled with the same colour of curve.

Any comment is appreciated

cs = csapi(Angle,DKTSCFMATRIX(1,:));
fnplt(cs,1,'-b^');
hold on
cs1 = csapi(Angle,DKTSCFMATRIX(2,:));
fnplt(cs1,1,'-k^');
cs2 = csapi(Angle,DKTSCFMATRIX(3,:));
fnplt(cs2,1,'-r^');

Sorry, they are. What about marker instances and filling them with the same edge colour?

Thanks

I have surfed through the internet what I found out was only line width can be changed for fnplt . There aren't much information about this function because it is not documented .

Hi Ulvi,

To my understanding, the intention is to modify the properties of markers created using ' fnplt '. As of now, the inbuilt function 'fnplt' does not have the functionality to achieve this. Thank you for bringing this to our attention.

As a workaround, you can modify the required properties using the handles to the graphic objects. I have attached the custom code below.

Angle = 0:45:360;
DKTSCFMATRIX=[1.60,    3.01,    3.50,    2.54,    4.01,    4.01,    3.61,    2.78,    1.60;
  3.28,    3.06,    6.75,    7.34,    3.21,    5.05,    6.39,    4.64,    3.28;
  1.16,    2.83,    5.24,    4.30,    2.92,    5.63,    6.55,    3.78,    1.16];
cs = csapi(Angle,DKTSCFMATRIX(1,:));
fnplt(cs,1,'-b^');
handle_axis=gca;  % returns handle to current axis
handle_recent_line=handle_axis.Children(1); % returns handle to recent line
set(handle_recent_line,'MarkerFaceColor',handle_recent_line.Color,'MarkerSize',4) % assigns line color to marker face and changes marker size
hold on
cs1 = csapi(Angle,DKTSCFMATRIX(2,:));
fnplt(cs1,1,'-k^');
handle_recent_line=handle_axis.Children(1); % returns handle to recent line
set(handle_recent_line,'MarkerFaceColor',handle_recent_line.Color,'MarkerSize',4) % assigns line color to marker face and changes marker size
cs2 = csapi(Angle,DKTSCFMATRIX(3,:));
fnplt(cs2,1,'-r^');
handle_recent_line=handle_axis.Children(1); % returns handle to recent line
set(handle_recent_line,'MarkerFaceColor',handle_recent_line.Color,'MarkerSize',4) % assigns line color to marker face and changes marker size
ylabel('SCF','fontsize',11)
xlabel('Polar Angle','fontsize',11)
hleg1 = legend('Left Brace','Middle Brace','Right Brace');
grid on
xlim([0 360])
xticks([0:45:360])
