Data Reader for Macintosh


If you want my honest opinion, just go get GraphClick, which is much better than DataReader, better supported and free.


Data Reader is a scientific application that allows you to read the data from a graph and export to an ASCII file for further processing. For instance, if you have a graph in digital format (e.g. a PICT file containing a digitized version of a figure or a screen capture of a figure in a publication), you can extract the data using Data Reader to use it in in a spreadsheet. Do not forget that you must always acknowledge the author(s) when using data that is not originally yours. It is available for Macintosh only and was tested on MacOS X, but should work fine on any system from 8.5.x I think. The 68k version and the Classic versions are not updated anymore. You can download the latest version from the following link:

Data Reader 1.6.1 Carbon.dmg

Data Reader 1.6 Carbon.sit

These older versions are still available:

Data Reader 1.3 Classic

Data Reader 1.3 68k

You require the latest version of Stuffit Expander to decompress it.

I welcome suggestions and bug reports at Send me an email if you want to be informed of new releases.


How does it work ?

How much does it cost ?

Data Reader is $10 shareware. You can register online if you wish at Kagi's secure web site. You can also use the Register program that accompanies Data Reader. Enter your name, your email address and the number of single user licenses you desire for each program you wish to purchase. Save or Copy or Print the data from the Register program and send the data and payment to Kagi. More specifics on the Register program to follow. Kagi handles my payment processing.

If paying with Credit Card, you can email or fax the data to Kagi. Their email address is and their fax number is +1 510 652-6589. You can either Copy the data from Register and paste into the body of an email message or you can Save the data to a file and you can attach that file to an email message. There is no need to compress the data file, it's already pretty small. If you have a fax modem, just Print the data to the Kagi fax number.

Payments sent via email are processed within 3 to 4 days. You will receive an email acknowledgement when it is processed. Payments sent via fax take up to 10 days and if you provide a correct internet email address you will receive an email acknowledgement.

If you are paying with Cash or USD Check you should print the data using the Register application and send it to the address shown on the form, which is:

1442-A Walnut Street #392-ZTP
Berkeley, California 94709-1405

You can pay with a wide variety of cash from different countries but at present if you pay via check, it must be a check drawn in US Dollars. Kagi cannot accept checks in other currencies, the conversion rate for non-USD checks is around USD 15 per check and that is just not practical. If you have a purchasing department, you can enter all the data into the Register program and then select Invoice as your payment method. Print three copies of the form and send it to your accounts payable people. You might want to highlight the line that mentions that they must include a copy of the form with their payment. Kagi can not invoice your company, you need to act on my behalf and generate the invoice and handle all the paperwork on your end. Please do not fax or email payment forms that indicate Cash, Check or Invoice as the payment method. As far as we know, there is still no technology to transfer physical objects via fax or email and without the payment, the form cannot be processed. Payments send via postal mail take time to reach Kagi and then up to 10 days for processing. Again, if you include a correct email address, you will hear from Kagi when the form is processed.

Road Map

Several things could/will eventually be added to the program:



Who made it ?

I am a Ph.D. student in quantum optics/condensed matter who got tired of reading data points on a graph with a ruler, a pen and a piece of paper.
