- 3.4 Sample Data
Summary
Origin allows the peaks from the result of frequency count. Also, fitted curves can added into the new layer in the histogram. What do you'll learn
- Plotting the histogram
- Using Frequency Count to do statistics
- Using Peak Analyzer to find peaks and do fitting
- Adding New Layers
Steps
Copy and paste the sample data into Origin and set the column as Y (Highlight the column and choose column:set as y from the Origin menu). Plot this data as a histogram by clicking Plot:Statistics:Histogram from the menu.
Frequency Count
- Highlight the sample data, then open the Frequency Count dialog by selecting Statistics:descriptive statistcs:f Requency Count.
- Click OK to finish. A new result sheet would be generated.
Fit Peaks
- Select Col (Counts) and then open the Peak Analyzer dialog from Analysis:peak and Baseline:peak Analyze R.
- in the Start page, select Fit Peaks as Goal , then click Next .
- in the Baseline Mode page, set the Baseline as y=0 when the Custom Radio box is checked.
- Click the Next button twice to go to the Find Peaks page. Click the Find button under the Enable Auto Find check box to find peaks.
- Click The Next button again to open the Fit Peaks page. Click Fit Control at the bottom of this page to open the Peak Fit Parameters dialog.
- In this dialog, the default fitting function is Gaussian , which are the right function for normalizing th E data. Close the Peak Fit Parameters dialog and go back to the Peak Analyzer dialog. Click Finish to complete the fitting.
Add The fitted Curves
- Activate the histogram graph and add a layer by selecting graph:new Layer (Axes): Right-y from the main menu.
- Right-click the Layer2 icon and select Plot setup from the short menu to open the plot setup di Alog.
In order to show all three panels in the plot Setup Dialog, please expand Plot Type panel by clicking and EX Pand Available Datapanel by clicking again.
Refer to plotting using the Plot Setup for more information.
- Select the sheet FitPeakCurve1 from the top panel, then set Col (C) as X and Col (D) as Y, and add them into the La Yer righty in the bottom panel.
- Do the same things for Col (E) and Col (F). After that, both fitted peaks has been added into the Layer righty.
- Click OK. Fitted curves had been added to the histogram.
- Double-click the graph to open the Plot Details dialog. Select righty from the left panel, then open the Link Axes Scales tab in the right panel and select Straight (1 to 1) for both X axis link and Y axis link. Click OK to close the dialog.
- The fitted curves is added into the histogram and the proper scale. The following is the result graph and the right y-axis removed.
