I sent the new tool to your email and you can try.
The new tool may be released this week. You can download it in our File Exchange page. We will also provide a link for this new tool in this page. |

Is it possible to get the zoom in tool? I need to zoom in to a particular color range. |
|
| 04/03/2018 | OriginLab | Hi vivek.garg,
This old tool doesn't support to zoom in. But we made a new tool which will be released soon, and it supports to zoom in. I sent it to your email and you can try. |

| 04/01/2018 | vivek.garg | Hi,
Thank you for providing this useful template.
I am running into an error with origin plotting. I am getting an error when changing the scales of CIE plot using this origin template. I want to zoom in a particular area on CIE color space to better visualize the variation of chromaticity coordinates I have plotted, which are closely spaced.
Can you please suggest. |

| 02/15/2018 | OriginLab | Thank you all for the recent comments! We will look into updating the App to support PL data. |

| 01/20/2018 | upconverted | This is a wonderful template, and it works like a charm. As suggested, your own (x,y) coordinates can be inserted in either the I(X5) and J(Y5) (CIE1931) or N(X7) and O(Y7) columns. You can also add your own two columns into the sheet and using the Plot Setup options of the selected CIE template graph you can add your points as a scatter plot to the graph. I prefer the second option, as it doesn't require to change anything in the I,J,N,O columns, which are basically used not for the presentation of desired points on the chromaticity graphs, but for governing the numerical labels (480, 540, etc.) on the boundary line, and that's why symbol size is set to 0. So this second option (adding own columns and own layer with a new scatter plot) is less invasive and leaves the template unchanged. For calculation of the (x,y) coordinates in the CIE1931 system, you have to use the three color matching functions established in the CIE 1931 norm. They are available in many sources throughout the Internet, and I find them quite simple from the mathematical point of view (not too complicated, just continous distributions with almost no distortions in their shape) and for my own use I have approximated them with Gaussian peaks with a very good quality of fit. That way, I do not have to extrapolate/interpolate the functions every time I need to use them on spectra coming from different detectors with different setpoints in the wavelengths, I just paste the mathematical formula of the fitted G |

| 01/18/2018 | pailendra | how to plot CIE with PL data |
|
| 01/09/2018 | nexako | This template very good!!, Open the graph template's window by double clicking on the worksheet's cell. And, open the plot details, Boundary I(X) click, symbol size change from 0 to 5, and apply. If you want CIE 1931 or CIE 1976 plots, inset the yours CIE (x, y) data in column (IX5), J(Y5) or (NX7), O(Y7), respectively. |
