Exporting plot data from Analyzer Plots
Overview
The OLI Studio can provide a wealth of information about a chemical system. Sometimes you are interested in only a small portion of the data and do not want to sort through all the output. The plot options can easily reduce the massive amount of data to a smaller, manageable amount. In this guide we will show you a typical procedure to accomplish this task.
Example
In this example we are plotting the pH versus the amount of sodium hydroxide in the solution. This technique will work for any plotted variable. You will need to specify the units you want to use since they can not be automatically changed once the data is exported. Also, apply any formatting and title changes you wish at this time.
Figure 1 Standard OLI Analyzers Plot Dialog
To start the export, click the View Data button.
This will display the data for the plot.

Click the box in the upper left-hand corner
Figure 2a - Selecting all data
Next select Copy from the drop-down menu. This will place both the plot (as a bitmap) and the plot data into the windows clip-board.
Start Excel
Next start your spreadsheet program. The example here uses Microsoft Excel 2003.
Select Edit from the menu line and then select Paste Special… from the drop-down menu.
Figure 3 Select Edit and then Paste Special
You will have several options. If you want the bitmap image to be in the excel document, select Bitmap.

To import the actual data, repeat the Edit/Past Special… procedure above.
Figure 6 the imported data
You may now manage the data within the spreadsheet. Please note, it is not necessary to import the bitmap image if you choose not to.
Exporting the plot to a graphics image file
Supported graphics images
The following file types are supported in the graphics export procedure:
BMP - Bitmapped files JPG - JPEG files PNG - Portable graphic files
Export Procedure:
Display the plot you wish to export (the following image is from a different file than the previous example)

Right-click anywhere on the plot:

Select Export…
Figure 9 Export Dialog
This dialog is similar to any windows file management window.
Specify the Save as type: file type. Bitmaps tend to have the highest resolution but are the largest files, JPEG files are more compressible but the higher the compression the greater the degradation of the image. PNG files are easily compressed and have little loss but are not supported by all graphics programs.
Switch to your working folder by using the Save in: box and then specify the name of your file.
