MATLAB: Linear scale graph for periodogram()

periodogram();linear scale;logarithmic scale

Hi,
I found that results given by periodogram() is always logarithmic scale. Is it possible to show linear scale in the graph?

If you can find the axis handle, you could try
set(AxHandle, 'YScale', 'normal')
This will not work if it is log data that has been submitted to the graphics routines; if that is the case you would have to replace the YData by exp(YData)
for H = findobj(AxHandle, '-property', 'YData')
  set(H, 'YData', exp(get(H,'YData')));
end
