Adjusting the appearance of your heatmaps in NetSpot

Licensed versions of NetSpot offer several ways of customizing the look of your WiFi heatmaps. You can make adjustments through NetSpot Settings accessible from the Main menu. In this article we’ll talk specifically about Heatmap and Survey settings.

Heatmap and Survey settings

NetSpot Wi-Fi analyzer for Windows is released

Additionally, you can make changes for each individual heatmap that you are currently working with by using the Heatmap Settings icon at the top right. The sliders in NetSpot are pretty sensitive, but if you feel like you need more precision, there is a spinbox next to each slider where you can select the exact values.

Available Heatmap Settings

Find the heatmap settings in NetSpot > Settings… in the top menu bar, then select the Heatmap tab. You’ll find the following options there:

  • Heatmap gradient: You have three choices for the color gradient. The first one covers the whole spectrum of the rainbow, with blue representing the most negative results and red representing the most positive ones. The second option has fewer colors (blue is removed) and reverses the spectrum so that red is negative and green is positive. The third has the fewest colors and simply ranges from blue (negative, cold) to red (positive, hot).
  • AP detection sensitivity: This setting determines which of the detected access points will be shown on the heatmap. It is based on the Signal Level strength of a particular AP. Move the slider towards -96dBm to include weaker APs, and move it towards -10dBm to filter out the weak ones. The default is -50dBm. Use the spinbox to the right of the slider for precision.
  • Individual Heatmap Settings: By clicking the drop-down menu under “Heatmap settings for:” you can select any visualization (including Passive scanning, Active scanning, and Troubleshooting) and adjust its settings. Please see the knowledgebase articles on the individual types of heatmaps to learn more about the settings for each one.
  • To reset all heatmap settings to their default values use the button at the bottom of the Settings window.

The “Show” and “Zoom” menus


Both menus can be found in the bottom left corner of the survey window. The “Show” menu includes the following options:

  • Floor plan

Check and uncheck to respectively show or hide the floor plan in the generated heatmap.

  • Walls

Check and uncheck to respectively show or hide the walls in the generated heatmap.

  • AP Marker size

Select from three options of AP marker size: small, medium, or large.

  • AP titles

Show or hide the AP brand and model titles under their markers.

  • Show the info panel for this step

You can tick this option in order to read the hints NetSpot offers for the currently active heatmap type.

The “Zoom” menu is supplemental to your zooming in and out with your mouse or trackpad.
