You cannot directly log the data from the Attribute scope.
One possible way to extract the data is to save it as a MATLAB Figure and then extract the data from the figure.
After you save the figure, open the figure and obtain a handle to the figure. You can use following command to obtain a handle to the current figure:
>>figHandle = gcf
You can extract the y-axis data using the following commands:
>> axesHandle = figHandle.Children(8);
>> lineHandle = axesHandle.Children(1);
>> yaxesData = lineHandle.YData;
