I am trying to match the colors in the label chart widget by changing the segment colors in the d3 pie chart widget.
The d3 pie chart can be downloaded from the following link:
https://community.ptc.com/t5/ThingWorx-Developers/label-above-pie-chart/m-p/540169
To change the segment colors, I followed the instructions provided by d3pie in the following link:
http://d3pie.org/website/examples/colors.html
I changed lines 127 to 132 in d3pie.min.js:
Before:
misc: {
colors: {
background: null,
segments: ["#0086ff", "#1bff31", "#de0e0e", "#ffa100", "#8dc3fa", "#6b6b6b", "#cbcbcb", "#ebebeb", "#ff13f2", "#a08965", "#7c0071", "#7cd685", "#ede2be", "#32ffff", "#ffee33", "#ffcdf3", "#bc0000", "#c58937", "#e1d04d", "#a6cd44", "#43a4c9", "#da5f5f", "#a4cba5", "#4f3ebe", "#2484c1", "#65a620", "#7b6888", "#a05d56", "#961a1a", "#d8d23a", "#e98125", "#d0743c", "#635222", "#6ada6a", "#0c6197", "#7d9058", "#207f33", "#44b9b0", "#bca44a", "#e4a14b", "#a3acb2", "#8cc3e9", "#69a6f9", "#5b388f", "#546e91", "#8bde95", "#d2ab58", "#273c71", "#98bf6e", "#4daa4b"],
segmentStroke: "#ffffff"
},
After:
misc: {
colors: {
background: null,
segments: ["#2484c1", "#65a620", "#7b6888", "#a05d56", "#961a1a", "#d8d23a", "#e98125", "#d0743c", "#635222", "#6ada6a", "#0c6197", "#7d9058", "#207f33", "#44b9b0", "#bca44a", "#e4a14b", "#a3acb2", "#8cc3e9", "#69a6f9", "#5b388f", "#546e91", "#8bde95", "#d2ab58", "#273c71", "#98bf6e", "#4daa4b", "#98abc5", "#cc1010", "#31383b", "#006391", "#c2643f", "#b0a474", "#a5a39c", "#a9c2bc", "#22af8c", "#7fcecf", "#987ac6", "#3d3b87", "#b77b1c", "#c9c2b6", "#807ece", "#8db27c", "#be66a2", "#9ed3c6", "#00644b", "#005064", "#77979f", "#77e079", "#9c73ab", "#1f79a7"],
segmentStroke: "#ffffff"
},
However, after the change, it is still displaying the old colors. Is the extension not referencing these color codes anymore?
Hi @Willie.
What version of ThingWorx are you running? Since the post you referenced containing the widget is over 2 years old, the widget may not be compatible with the current releases of the product. Unfortunately, we don't have an updated version but you can request one on the ThingWorx Ideas forum.

Hi @Willie
You may want to consider using the built-in Pie Chart widget that is officially supported and allows for Fixed-Style or State-Based Formatting out of the box.
Hi @c_lowy
The built-in pie chart doesn't work well. It doesn't display values when hovering over with a cursor and cannot do donuts. The d3 pie chart is functionally and aesthetically better except for the customization of the segment colors.
It appears that the color is being assigned from the Style definitions (line 226-229 in the runtime js file)
if (formatter != undefined) {
formatResult = TW.getStyleFromStateFormatting({ DataRow: rows[i],
StateFormatting: formatter });
value.color = formatResult.backgroundColor;
}
I wonder if removing that would force it to use the code you referenced above.

Actually that may not be the cause. Did you replace the d3pie.min.js with a non-minified version of the library?
