The following relationships are being used to convert image pixels to data:
Export a JSON file containing the axes calibrations, digitized data and measurements. This JSON file can be loaded to resume work at a later time. You can also download a combined 'project file' which includes this JSON and also the image in a single TAR file.
Project name: .json/.tar
Load a previously exported JSON or project file (.tar)

Click to select a data point. The following keys can then be used to adjust the position:
| Cursor (Arrows) - | Move up/down/right/left |
| Shift + Cursor - | Faster rate of movement |
| Q - | Select next point |
| W - | Select previous point |
| Del/Backspace - | Delete point |

Point groups are groups of related data points such as standard error or confidence intervals. To define a point group, enter a name in the text input below. Create additional point groups as necessary. E.g. Assume we have 3 point groups defined: Median, Standard error +1, and Standard error -1. Points would be entered in the order shown in the image to the right. For each set of points, the median value would first be recorded, then the standard error +1, and finally the standard error -1. The process would repeat for the next set of points. |
