Heatmap-style chart of data organized as columns per timestamp

I have data inserted every 200ms into an Influx-DB. Each Iinflux-“point” (=dataset/row) comprises 1024 influx-“fields” (=columns) with floating point values. I want to display this data in a heatmap-style chart. Instead of aggregating the data from the many fields into a histogram telling me the frequency of the values, I want to visualize the 1024 values per timestamp in a way that the color code represents the numeric value in a “cell” instead of a frequency.

How can I do this? I hope it became clear what I want…

can you please provide sample data? inline csv would be nice

Take a look at the Mosaic Plot plugin. I think it matches your use case
