in this video we will demonstrate the
quick peaks gadget in orange in 2015
including tagging Peaks and single plots
grouped plots and multi-layer graphs
creating and reusing a gadget theme
improving the generated baseline hiding
the ROI box and controls and other
advanced gadget features let's start by
using the submission spectrum to
illustrate simple peak tagging to open
the gadget go to the gadgets menu quick
Peaks open dialog let's click the ok
button to accept the default settings
let's extend the ROI box to cover all of
the peaks in origin 2015 you can double
click on the ROI box to open the
Preferences dialog again
from the baseline tab we'll change our
mode from second derivative to constant
the range to full plot range and we'll
set the constant to be minimum when we
click the apply button the small peak in
the lower right of the ROI box will no
longer be tagged
but we can correct for this we'll go to
the fine peak tab set our direction to
positive our local points to 3 and our
threshold Heights percent to 10 percent
now when we click on the apply button
the peak will be tagged again now we'll
go to the output tab
and make sure our results are appended
to a worksheet now we'll go to the
quantities tab and make sure our data
set identifier is set to book sheet long
name we can click OK to close the dialog
we're not interested in the series of
peaks below about four ten nanometers so
let's adjust the ROI box to exclude them
now we can output our results go to the
gadget flyout menu and select new output
before we close the gadget let's say
these settings is a theme for future use
you
now we can close the gadget
forget it approaching to explore we can
see a workbook has been created by the
gadget
this workbook contains a worksheet
holding all the data related to each of
the peaks that the gadget is found
let's close this workbook and close this
graph now let's look at using the quick
peaks gadget with a grouped plot let's
open the gadget again from the gadgets
menu
you
we'll load the theme we just created
into the gadget and click the ok button
we can see in the ROI box that the
gadget is focused on the first plot in
the group
however we can change the selected plot
by going to the gadget flyout menu
change data and will change the plot
we can easily generate output for all
curves in the grouped plot by going to
the flyout menu and selecting new output
for all curves let's close our gadget in
the graph we can see that our peak
labels are either partially obscured or
overlapping we can easily correct for
that double click on a peak label to
open the plot details dialog in the
label tab select Auto reposition to
avoid overlapping show leader line if
offset exceeds we'll set that value to
zero and we'll select polyline vert for
our connect style let's do this for both
of our tag plots
you
we can click the ok button we can now
reposition our labels to select an
individual label hold down the control
key on the keyboard and single click in
the label click again in the label
holding down the mouse button and drag
it to a new position
you
we can continue moving as many labels as
we think is necessary
let's close this graph now let's take a
look at using the quick peaks gadget
with multi-layer graphs he'll open the
gadget the gadgets menu select quick
peaks and we'll click on our theme name
directly
the gadget with our theme settings has
loaded into the first layer of the graph
to tag the peaks for all four layers in
the graph go to the gadget flyout menu
and select new output for all layers
you
we can see that the peaks and all four
layers have been tagged we can go ahead
and close the gadget
let's go to the project explorer and
reopen our result workbook
we can see the data for the peaks from
all four layers
let's close the workbook and close the
graph now let's look at some of the
advanced features of the quick peek
gadget we go to the gadgets menu open
the gadget with the default settings and
click the ok button
let's try to improve the default
baseline when the gadget Preferences and
from the baseline tab will keep our mode
as second derivative but will change the
range to full plot range for our
smoothing method will select Savitsky
goal a set our window size to 6 and our
maximum anchor points to 16 when we
click the apply button we see that the
baseline has been improved
there's a new feature in origin 2015
that allows us to temporarily hide the
ROI box and gadget controls if we click
on the small button in the upper right
corner of the graph window labeled H we
will see that the ROI box and gadget
controls will be hidden while the gadget
output remains visible on the graph we
can click the button again if we wish to
show the gadget controls
the gadget also allows us to fit our
peaks switch to the more powerful peak
analyzer and subtract our baseline
we can also select individual Peaks
we'll adjust the ROI box
click new output from the flyout menu we
can open our report worksheet we can see
that peak has been listed in the sheet
let's drag the ROI box to another peak
and click new output we can see that
peak has been included in the sheet
finally we can close our gadget this
concludes our demonstration of the quick
peaks gadget in origin 2015 thank you
for watching
