Not able to extract data from fig file having subplots

There are 7 subplots in my fig file , am able to extract data from all but not able to extract data from 6 fig .

Could anyone tell me why the 6th subplot data am not able to extract am using this code.Once i execute the command

the data gets vanished from the figure file

clc
clear all
h=findobj(subplot(7,1,6),'Type','line');
x=get(h,'Xdata');
y=get(h,'Ydata');

for i =1:size(y)
    z{i,1}=(y{i,1}');
end

Does axes 6 also contain a line object? Maybe it contains some other graphics object.

[Sandeep Nair]

Yes ,it looks like line object only,whenever am executing the command for sixth subplot the h value is 0x0 graphics placeholder

[Ameer Hamza]

h = 0x0 means that it is not a line. Can you share your .fig file.

[Sandeep Nair]

sorry,i cant share the fig file ,can you please tell me other options which i can try

[Ameer Hamza]

Check what type of graphic object is present. What is the output of these lines

ax = subplot(7,1,6);
ax.Children

[Sandeep Nair]

When i open the file i can see the figure with data on it .

When i ran the command

get(subplot(7,1,6),'Type')

it returned

'axes'

when i open the file i can see the data and i can see the datatips as well ,but when am running command for findobj

the graph is disappearing.Please help

[Ameer Hamza]

Without knowing what is present in subplot 6, it is difficult to suggest a solution. The children property tells what type of object is children of that axes.

[VBBV]

clc
clear all
ax = subplot(7,1,6)
h=findobj(ax,'Type','line');
x=get(h,'Xdata');
y=get(h,'Ydata');

for i =1:size(y)
    z{i,1}=(y{i,1}');
end

use the property, value type arguments for findobj . pass the handle of subplot to findobj
