显示 更早的评论
hey guys
im triyng to build a plot in gui witch get from user the x scale and jumps , y scale and jumps , style and color
for some reason im not sure if im getting it right , can someone give me some lead for it ?
thx!
the code ( only the sector when pusing the plot button)
% Button pushed function: plotButton
function plotButtonPushed(app, event)
Xdata= (get(app.XbeginEditField):get(app.XendEditField):get(app.XjumpEditField));
Ydata= (get(app.YbeginEditField):get(app.YendEditField):get(app.YjumpEditField)) ;
LineStyle= get(app.StyleEditField);
Color= get(app.ColorEditField);
plot(Xdata,Ydata,LineStyle,Color);
end
end

Three main things to be aware of:
1) In MATLAB, using the colon operator to specify a vector: the syntax is "begin:jump:end" rather than "begin:end:jump"
2) Usually you will use get with two input arguments: first the object and second the property. Using only the first argument will return a struct of all properties for that object.
3) With edit boxes, you will typically get the 'String' property, and then convert that to a numeric value with str2num or str2double if necessary.
So with those things in mind:
% Button pushed function: plotButton
function plotButtonPushed(app, event)
Xdata= (str2double(get(app.XbeginEditField,'String')):str2double(get(app.XjumpEditField,'String')):str2double(get(app.XendEditField,'String')));
Ydata= (str2double(get(app.YbeginEditField,'String')):str2double(get(app.YjumpEditField,'String')):str2double(get(app.YendEditField,'String')));
LineStyle= get(app.StyleEditField,'String');
Color= get(app.ColorEditField,'String'); % Note: I'm assuming your program expects a string color specification, e.g., 'k', 'g', 'r', etc.
plot(Xdata,Ydata,LineStyle,Color);
end

Apparently AppDesigner allows different types of edit boxes: EditField and NumericEditField. I don't know which type(s) you have, but StyleEditField should be an EditField (since a line style is non-numeric), ColorEditField could be either one depending on how the line color is specified, and the others (X,Y) can be NumericEditFields.
With EditField or NumericEditField, you'll get the 'Value' property (rather than the 'String' property - which is for edit boxes made in GUIDE), and that'll be a numeric value for NumericEditField or a string (or character vector) for EditField. So there's no need to convert a string to a number for NumericEditField. So, assuming that the ones for X and Y start, jump, end are all NumericEditFields and the others are EditFields, the code would look like this:
% Button pushed function: plotButton
function plotButtonPushed(app, event)
Xdata= (get(app.XbeginEditField,'Value'):get(app.XjumpEditField,'Value'):get(app.XendEditField,'Value'));
Ydata= (get(app.YbeginEditField,'Value'):get(app.YjumpEditField,'Value'):get(app.YendEditField,'Value'));
LineStyle= get(app.StyleEditField,'Value');
Color= get(app.ColorEditField,'Value'); % Note: I'm assuming your program expects a string color specification, e.g., 'k', 'g', 'r', etc.
plot(Xdata,Ydata,LineStyle,Color);
end
