The ratio of physical values on y -axis is 0.0002 per pixel
The pixel location of the origin of the plot is at 30 pixels from the right and 211 below the origin of 314x235 pix picture.
The formulas used to relate the pixel location to the physical variables:
For x-axis;
[(X axis of the pixel location value)-30]*0.0005
For y-axis;
[211-(Y axis of the pixel location value)]*0.0002
Below are the values I tabulated
| X axis of the pixel location | Y axis of the pixel location | x | y |
| 50 | 149 | 10 | 12.4 |
| 70 | 106 | 20 | 21 |
| 110 | 76 | 40 | 27 |
| 150 | 74 | 60 | 27.4 |
| 190 | 83 | 80 | 25.6 |
| 230 | 99 | 100 | 22.4 |

I will grade myself in this activity as 10.

Hi Jorge,
Your work looks good. Please put the journal and paper biblio in your report. I want to know what year and which journal you got this graph from. Also, indicate who helped you or if you did it on your own.
Billy helped me find the paper. The paper came form the Chemistry Journal but I'm not so sure about the year.
