Extract data from UIAxes in AppDesigner
显示 更早的评论
Hello, I'm devolping an app in AppDesigner and I want to extract data from a UIAxes.
I have several different actions before I can extract the data. I wanna press a button, after all those actions are done, and extract the data from what is plotted in the UIAxes.
Any suggestions?

If you are using lines, you just have to call "XData", "YData" and "ZData" of your uiaxes's childrens. For example:
>> plot(app.UIAxes, randn(1001,1));
>> app.UIAxes.Children
ans =
Line with properties:
Color: [0 0.4470 0.7410]
LineStyle: '-'
LineWidth: 0.5000
Marker: 'none'
MarkerSize: 6
MarkerFaceColor: 'none'
XData: [1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 … ]
YData: [1.6302 0.4889 1.0347 0.7269 -0.3034 0.2939 -0.7873 0.8884 -1.1471 -1.0689 -0.8095 -2.9443 1.4384 0.3252 -0.7549 1.3703 -1.7115 -0.1022 -0.2414 … ]
ZData: [1×0 double]
>> ax.Children.XData(1:10)
ans =
1 2 3 4 5 6 7 8 9 10
