Plot gain vs frequency (GUI)

The capacitor result is working
But the plot is giving an error and cannot draw gain vs freq
This is the code:
function calculate_button_Callback(hObject, eventdata, handles)
option = get(handles.r_values, 'value');
switch option
case 1
R = 1000;
case 2
R = 2000;
case 3
R = 3000;
case 4
R = 4000;
end
f_c = get(handles.fc_value,'string');
f_c = str2double(f_c);
c_value = 1 / (2*pi*R*f_c);
c_value = num2str(c_value);
set(handles.cap_result,'string',c_value);
function plotbutton_Callback(hObject, eventdata, handles)
r_value1 = get(handles.r_values,'value');
switch r_value1
case 1
R = 1000;
case 2
R = 2000;
case 3
R = 3000;
case 4
R = 4000;
end
c_value1 = get(handles.cap_result,'string');
if get(handles.highbutton,'string') == 1
Gain = tf(R*c_value1,1 + R*c_value1);
bode(Gain)
elseif get(handles.lowbutton,'string') == 1
Gain = tf(1,1 + R*c_value1);
bode(Gain)
end

If you have the Control System Toolbox or the System Identification Toolbox, you can try using bodeplot instead of bode, which will allow you to specify the (UI)Axes to plot into and other options.
References:
(They seem to be the same function in two different toolboxes, judging by their documentation pages.)
