The image coordinate is the pixel location within the image. Any data points that you have already created will be automatically adjustedĪlso, if you desire to replace the current calibration with a completely new one (as opposed to fine-tuning the existing calibration), simply clickĪs you move the mouse over the image, you will notice that the Image Coordinates and Data Coordinates information bars will begin to show informationĬoncerning the current mouse location. Using the arrow keys to move the calibration point to the desired location. Remember that you can still fine-tune the location of the calibration points by pointing at them with the mouse and After filling in this information, your calibration data values will display in red or green next to the That corresponding to each of the calibration points this is shown in the screenshot below.įor XY plots, you will specify the data values for the two points selected on the X axis, and thenįor the two points selected on the Y axis. Once the second Y calibration point is selected, the calibration dialog will appear to allow you to input the data values The Y axis calibration points will be indicated by green points In the same manner as the X axis was calibrated, click on the YĪxis at the lowest possible tick mark on the Y axis, and then at the highest possible tick mark on the Y axis. You may fine-tune the calibration points at a later time as well.Īfter specifying the X axis calibration, we will now specify the calibration for the Y axis. The canvas will look similar to the screenshot below. Of your calibration points, connected by a red line. A red dot will be placed to indicate each Use the magnifier to aid in this fine tuning. Until it adequately lines up with both the axis and tick mark. Location of the point you chose by hovering the mouse over the red dot that you just created, and using the keyboard arrows to shift the dot You will soon be asked which data values (in the x direction) these two tick marks correspond to.

ForĪn XY plot, you will first click on the leftmost tick mark possible on the x axis, and then click on the rightmost tick mark possible on the x axis. Click the Calibrate… button, and follow the prompts that are given beneath the toolbar.

However, CurveExpert Professional supports digitizing from XY plots with the x and/or y axis on a log scale, and also supports Once the image is in place, you may select the type of the graph in the image from the toolbar. To exit the digitizer and save the current dataset, click OK to exit the digitizer while discarding your current work on the To the left of the OK and Cancel buttons. Finally, the path to the currently selected image is shown along the bottom of the window, The bottom left area is a magnifier, where the contents of the image and overlay underneath the mouse crosshairsĪre magnified by a factor of 2X of the 100% image size. The image, current calibration, and currently selected points are shown in the canvas area in the bottom The data values that have been digitized so far are shown in the “Dataset” To remind you what you are working on in the digitizing process. Beneath the toolbar, an informational message will appear that is intended You move through the digitization process. The toolbar is shown across the top, with the appropriate buttons only being enabled at the appropriate times as The layout of the digitizer dialog is shown below: Selecting of the data points tells the digitizer which locations you would like to have digitized Calibration is the means by which you describe where the axes of the plot are located, and how those axes Selecting the image is straightforward the image can either be read from a file on disk, or pasted from theĬlipboard. In general, there are three primary steps Through the digitization steps as documented in the following sections. This will begin the digitization process first, you will be able to select the image, and then the dialog leads you Intrinsically by the transformations performed by the digitizer engine. The digitizer supports Cartesian (XY) and polar plots XY plots can have semilog or log-log axes. To successfully digitize informationįrom an image into data, information about how pixels in an image map to real data must be collected by the application,Īnd the digitizer leads you through this process. This context, means to convert content from an image into a usable dataset). In CurveExpert Professional, you can use theīuilt-in digitization capabilities in order to extract the data present on an image into a dataset (to “digitize”, in In some cases, the data to be analyzed is in the form of a picture or image.
