MATLAB: Date picker in app designer

app designerdate pickerduration

Hi there, I have recently started designing apps with App Designer and I am new to this.

So my app is supposed to handle financial calculation i.e set up amortisation tables for loans etc.

So I have two date pickers one for the start date and the other for the end-date. I have written a function that calculates the duration between two dates using years(d2-d2) but now when I try to display the date on an edit field { app.TermtoDate.Value = app.numberofperiods} I get an error message saying the value must be a double….

here is my code:

function Duration11(app,d1,d2)

start = datestr(d1)

enddate = datestr(d2)

app.numberofperiods = years (enddate-start)

**where numberofperiods is initiated as a property

I called this function under a buton callback

You are converting date into string using datestr. You can directly subtract the date time object. years(d2-d1)

I was able to get most of the datepicker to work now.

 age = app.DatePicker_DoB.Value;
            DisplayFormat = 'yyyy-mm-dd'; %
            datenow = datestr(now, DisplayFormat); %DisplayFormat
            ageout = datestr(age - datenow, 'yy');
            app.TextArea_ageNEQO.ValueChangedFcn = {ageout, string};         
            app.TextArea_ageNEQO.Value = [ageout];
            if app.TextArea_ageNEQO.Value == ""
                uialert(app.UIFigure, {'You need to enter your', 'date of birth to proceed.'}, 'Error', 'Icon', 'Error');
            end

In general, always specify axis handles when plotting. This is especially important when creating plots from a GUI. The reason your data aren't appearing on the plot is because animatedline() doesn't know what axes to use. If you specify the axis handle, the problem will be solved. So you'll need to create the axes before creating the animaledline object.

figure
ax = axes;  %don't use gca, it's not specific enough for GUIs.
app.h=animatedline(ax);
