Listed below are file formats that you can import into DataGraph. Note for all understood file formats you can simply drag and drop the file, either into the data table, or the column list. When files are dropped onto the column list, DataGraph will automatically place the new columns in a group, using the file name as the name for the group.
Ascii Text is not a single file format. The most common types are tab delimited files or comma separated files (CSV). There is also space separated, and other separators such as | (a vertical bar).
When you drag a text file into DataGraph, the program will automatically determine the column separator or delimiter to use. DataGraph reads the start of the file and determines from there what separator is being used.
If a tab is found that will be used as the only separator. If not the presence of a comma will force a comma separator.
Multi-line entries are applicable as long as they are enclosed in quotes. The line-breaks are changed into ‘\n’, to indicate a new line.
CSV is a type of text file where each column is separated by commas. You can open CSV files directly in DataGraph.
DataGraph can be set as the default program for opening CSV files. From the Finder or the desktop, control-click on the file and select Get Info.
Find the Open with section of the info box. Use the menu to select DataGraph. To apply to all files, click the Change All button.
If the Excel file has multiple sheets, DataGraph will import every column from every sheet. If you drag and drop a multi-sheet file onto the column list the Excel file name will be used to form a group and the sheets will be used to create subgroups.
You can also use Import Excel Sheet from the command menu. This brings up a dialog box that you can use to highlight the section of the sheet you want to import.
Matlab is a widely used programming application. You can save data in Matlab and import it into DataGraph. You can also use DataGraph from the command line so you can call it from within Matlab.
DataGraph understands the version 4 binary file format, but the save routine can easily save variables in that format. DataGraph will only import column or row vectors, and ignore matrices. The name of the variable will be used as a column name.
In matlab, if you have vectors a,b,c. Save them using
save output.mat a b c -v4
Then import the output.mat file into DataGraph.
Import netCFD files directly into DataGraph. Note that DataGraph cannot import netCFD-4 Files. For more information and example files see: https://www.unidata.ucar.edu/software/netcdf/examples/files.html
DataGraph supports all of the data formats that Cricket Graph used throughout it’s versions, ending in Cricket Graph III. A licensed version of DataGraph is needed in order for this importer to work.
DataGraph is also designed so that other graphing tools should not have problems reading data from a DataGraph file.
DataGraph can import files from the latest version, and possibly previous versions. The graphs are ignored, but the data is imported.
If you want to see additional formats supported, post on the discussion board.
