Heatmap Options and how they work
Posted: Wed Jun 24, 2009 9:52 amHi all,
I finally want to take a moment and put the forum to good use by posting a quick rundown of the heatmap generation options found in Heatmap studio and what they do. Eventually this will be included in the help file for HMS whenever it reaches final versions! Feel free to sign-up and ask any questions you may have!
1. Color spectrum (Low --> High)
These five button allow you to change the color scaling of your heatmap to anythign you choose! Simply click on each button and a color selection dialog will appear. Choose you color and you will see the updated spectrum below the five buttons. Here's a screenshot of what custom colors look like:
2. Heatmap Opacity
The Heatmap Opacity control dictates how dark the background of the overlayed heatmap is. Here are some screenshots to show the differences:
Opacity set to 50:
Opacity set to 100:
3. Blob Size
This control set the size of the dots that are drawn to make up the heatmap. Here's an example:
Blob size set to small:
4. Decay
THe decay option determines how far out from the data center the heatmap expands. The larger the decay the larger your heatmap will be drawn outwards. WARNING: Increasing the decay increases hetmap generation time (in some cases depending on size and number of data points generation could take 5+ minutes) Here are some examples:
Decay set to 10:
Decay set to 50:
5. Heatmap Threshold
The threshold of a heatmap determines where the data falls in the color spectrum. For example: If your data range is 1 through 10; 1 being green and 10 being red and you set the threshold at +100 then 1 will become red as well (including everything in between) Here are some examples:
Threshold at +50%
Threshold at +100%
