Published data can be
This example shows a graph of fracture test data. Assume that this is published in the
literature and you would like to add your data to it to show agreement or disagreement and
then re-publish all the data in your own paper (with copyright permission from the other
author). Instead of manually picking off points, have Grab It! record the points for you.
It's much faster, and more accurate.
Any picture with a scale
mark can be measured.
The screenshot below shows a micrograph with a 1 micron scale mark in the lower right
corner. Measurements of the width of the "needle" shaped features are shown in
column C. This principle can be used with maps, schematics, micrographs, or any photo with
a scale mark. The speed of just clicking on two sides of a feature and the accuracy of the
results make this a simple and valuable feature.
A downloaded chart is
easily changed into data.
This picture shows two stocks (Dell and Msft) on a chart, along with the actual data
reported by Grab It! on the right. Set 1 is Dell, and Set 2 is Msft. Grab It! gives
as many data points as you want to click.
As a note, this graph is linear scale, and could probably be read without a lot of pain.
If this were log scale (common for stocks), that would not be the case. Grab It! handles
log and linear with ease.
