Change plot properties generated from a curve fitting

Hello,

I am trying to remove the markers and change the line properties from a plot made by rational fit. I tried different options such as Marker, none and Linestyle but it did not work. I have event tried h.Marker='none' and no success. Any idea how to solve this?

[fitresult, gof] = fit( xData, yData, ft, opts );
% h = plot( fitresult, xData, yData, 'Linestyle', 'none','Color','k', 'Marker',marker_style{i} );
h = plot( fitresult, xData, yData);
h.Marker = 'none';

Thanks

By the way, using h=plot( fitresult); gives me a wrong fitted plot and hence I have to use h = plot( fitresult, xData, yData);

I’m not at my computer right now, but can you access the properties you want from the property inspector dialog? Or are they within a "child" of h?

Yeah. You are right. Thanks

Since the object contains 2 lines try calling them specifically. For example:

h(1).Marker='none'
h(2).Color=[.5 .5 .5]

Thank you. This helps. However, I still see the lines and data in the legend. I am plotting 4 sets of data in a for loop, so I do not want to define specific handle for each plot to manipulating the legends. Could you help learn how to remove the line and 'fittted curve' from the legend? I waant to define legend later for markers ('data' here) so the text legend for markers should also be modified.

OK. I figured out to fix this issue by defining the figure handles in the loop as a cell array.

h{k} = plot( fitresult, xData, yData);
h{k}(1).Marker = marker_style{i};
h{k}(2).Color=[.5 .5 .5];

and out of the loop

legend([h{1}(1) h{2}(1) h{3}(1) h{4}(1)], legends_text{1},legends_text{2},legends_text{3},legends_text{4},'AutoUpdate','off')
