Chart Image Utility is targeted at users who interact with published charts of data and need to get accurate interpolated values of the underlying dataset. This is a common problem in many engineering fields. The extension provides an alternative to estimating by eye or printing the chart and using a pencil/ruler approach.
The extension works on charts with linear axes and is easy to use. The user first uploads an image of the chart. Then reference points are selected by the user to define the origin and reference points on each axis. The user then populates the corresponding value in axis units associated with each reference point. Finally, the user can then click on the chart and a table is populated with the coordinates of the clicked point in chart units.
Extore is a team of professionals who are passionate about creating extensions for web browsers. This devotion also gives us opportunity to appreciate work of other people. We get inspired by useful, open source extensions made by developers all over the world. Our strong belief is that one should share helpful add-ons with others. That’s why we’d like to present you our ever-growing list of favourite extensions that have inspired us. Moreover, as you probably have already learned, sometimes struggling for the best brings an end to the good. Talking about add-ons it often turns out that an upgrade is worse then previous version. Also it can become really tricky to get back to the beloved version of your favourite extension. That’s why we’re going to make not only the latest, but all versions of our favourite (and we hope yours too) add-ons available for download. No more compromises, just stick to the version you really like!
