heat map of high dimensional data

Hello:

I have a matrix of data of huge dimension, 100x64. I wish to plot heatmap; could anyone suggests nice way to plot heatmap for such high dimension data?

Please share the data range (Matrix)?

Or Try with this?

imagesc(data);
colorbar;

could you show it randomly generated data that ranges between 0 and 1?

This I know.. my concern is visibility issue;

[KALYAN ACHARJYA]

Yes, it is quite difficult to display high-size matrix data at the face of grids. Is it necessary, because data in the 0 and 1 range, you can display data in a different color range? Display data to get general view?

[KALYAN ACHARJYA]

data=rand(100,64);
imagesc(data);
colorbar

Have a look on pcolor, imagesc, heatmap.

Hi Poulomi,

These are a few methods you could try on your dataset to generate heatmaps.

1. imagesc: Display image with scaled colors
2. heatmap: Create heatmap chart
3. pcolor: Pseudocolor plot

Hope this helps.
