Karin, thanks for catching that oversight. Jonathan, technically "iscellstr" is correct but since the text function allows empty numeric values as the string, I will change it to iscell.

The changes will be in today's update. Thanks!

Hi everyone. Thanks for the comments/feedback. I have updated the function with fixes and new features:
* It now correctly handles the labels for small matrices with labels.
* There are two options minColorLevel and maxColorLevel that allow you to specify how the data range maps to the color range. This is useful when comparing heatmaps and ensuring the same color-data mapping between heatmaps
* There is now a nanColor option that allows you to specify a special color for missing data elements.

Izi, that error seems to suggest that you are calling the genPredictors function without any inputs. “data” is a required input for the function and needs to be specified. See loadScriptNN for an example of how to use this function.

Satya, is the Neural Network predicting 0 load in MATLAB or in the Excel spreadsheet? If it is fine in MATLAB you may need to investigate if the model is being loaded correctly in the Excel side.

Jose, this function won't eliminate the dead space you see because it only modifies the ticks that would be drawn by datetick. What you need is the ability to modify the x-values in your dataset so that when they are plotted the data are no longer evenly spaced in the x-dimension. This is a much more challenging problem that this function is not set up to address.

17 Mar 2014 Customizable Heat Maps Visualize data as a heatmap with many customizable options. Author: Ameya Deoras arnold

Hi,

nice improvements. I got one big problem with the colorbar:
How do I set a ylabel to the colorbar?

Another idea for NaNs would be to just leave out the text "NaN" as well, simply don't show any text in those fields.

Something else I thought of:
the y-labels of the colorbar are always set automatically (or is there a way I don't see?). One tick is close to the top, as it should be, yet there is no label close to the bottom of the colorbar. This is not nice. They should be evenly spread across the colorbar with one close to the top value and one close to the bottom value. :)

This is an excellent utility and I appreciate the effort of the creator Ameya Deoras.

I had only minor difficulties accessing the 'Xlabel' and similar attributes. Users should be aware that the "colormap" property is critical for proper visualization (as acknowledged by author).
