word coloring by sentiment factor

[derlykk]

Hello,

I would like to visualize a text cloud of words which also went trough an sentiment analysis (value from 0.0 - 1.0 describing how positive the text is) and use the sentiment to color the words from color red to green with color intensity dependent on the sentiment score.

Does anyone have idea how to achieve this or does need something similar?

Thank you!

I have the same feature request. On the front end, we would need a colorization function in the Format pane of the visual, and an additional axis to add that sentiment column to the visual. On the back end, the word cloud's color function needs to respond to this.

If this is easy to do, I may be able to make the changes to the code, but I haven't coded a Power BI visual before.

I forked the project and implemented the colorization function: https://github.com/juleskuehn/PowerBI-visuals-WordCloud
