12 Ansichten (letzte 30 Tage)
i had created a app through app designer ,which import and read data from excel and shos it in uitable now i have put two dropdown meny one for x and one for y and the user selects the column name to plot accordingly ,now i have to modify the code so that i can select multiplecolumn names from dropdown menu so that multiple graph would come according to user selection .
below is my code which i have written ,plzz help me modify it
classdef app1 < matlab.apps.AppBase
% Properties that correspond to app components
properties (Access = public)
UIFigure matlab.ui.Figure
readexcelButton matlab.ui.control.Button
UITable matlab.ui.control.Table
xDropDownLabel matlab.ui.control.Label
xDropDown matlab.ui.control.DropDown
yDropDownLabel matlab.ui.control.Label
yDropDown matlab.ui.control.DropDown
UIAxes matlab.ui.control.UIAxes
% Callbacks that handle component events
methods (Access = private)
% Button pushed function: readexcelButton
function readexcelButtonPushed(app, event)
[file, path] = uigetfile('*.xlsx');
if isequal(file,0)
msgbox('Please input an Excel file')
t = readtable(fullfile(path, file));
app.UITable.Data = t;
% Set column names as a pull down menu
app.xDropDown.Items = t.Properties.VariableNames;
app.yDropDown.Items = t.Properties.VariableNames;
plot(app.UIAxes, app.UITable.Data.(app.xDropDown.Value), app.UITable.Data.(app.yDropDown.Value));
% Value changed function: xDropDown
function xDropDownValueChanged(app, event)
value = app.xDropDown.Value;
plot(app.UIAxes, app.UITable.Data.(app.xDropDown.Value), app.UITable.Data.(app.yDropDown.Value));
% Value changed function: yDropDown
