Hi,
I tried the attached image and I noticed that the X-axis is log scale where as Y-axis is linear. Make sure you checked the "log scale" option for x-axis while specifying the axes points. I tried extracting data from that image, and I was able to reproduce correct numbers.
Also, make sure the limits that you specify in that dialog box are same as the points you clicked on while aligning the axes.
In short, do the following after hitting "Align Axes":
- Select X-Y plot
- Click on two points on X-axis and remember the x-values for those (say: x1 and x2, where x1 < x2) .
- Click on two points on Y-axies and remember the y-values on those (say y1 and y2, where y1 < y2).
- After clicking 4 points a dialog appears asking for limits. The x-limits are x1 and x2 and y-limits are y1 and y2. Make sure to check "log scale" check box on X-axis.
- proceed to data extraction by clicking "Acquire Data". You should also be able to see correct x,y numbers below the zoomed image as you hover over the image after alignment.
Let me know if you still have problems,
Cheers,
