MATLAB: What does “Line cannot be a child of line” mean

errorplot

When executing this, it says Error using plot Line cannot be a child of Line.

Error in TestMySquareII (line 11) plot(scale,y,'r*'); I do not know why.Hope someone can help me figure out. Thanks.

semilogx is a command that plots values, it is not a transformation. The output is handle to a line object, not x-values that you can use in the subsequent plot command. So, get rid of the plot command as

semilogx(x,y,'r*')

alone would most likely give you the desired result directly.

See the documentation of semilogx for more info.

You need to create an axes object first so you can use that as the parent object instead.

fig_UPS = figure;
ax=axes('Parent',fig_UPS);
hold(ax,'on')
plot3(ax, handles.VolDensPot_UPS, handles.PesoDensPot_UPS, handles.Rend_UPS, 'Color', 'r', 'Marker', '*','DisplayName',  handles.Nome_UPS, 'LineStyle', 'none');
plot3(ax, handles.VolDensPot_Wendell, handles.PesoDensPot_Wendell, handles.Rend_Wendell, 'Color', 'b', 'Marker', 'o','DisplayName',  handles.Nome_Wendell, 'LineStyle', 'none');
legend(ax);
xlabel(ax, 'Densidade de Potência Volumétrica [kW/dm³]');
ylabel(ax, 'Densidade de Potência Mássica [kW/kg]');
zlabel(ax, 'Rendimento')
