Building your first analysis

Now you have connected your hardware to your web service you can build the first view to collect and analyse your data.

In Purrmetrix ‘views’ are the blocks that you use to organise your sensors and carry out an analysis. These can range from something simple like a bar chart or more complex like a dew point analysis.

For most users, the best starting point is a heatmap view. Heatmap views let you locate your sensors in a plan or picture of your building and gives you a great overview of what is happening, highlighting areas and times where you might want to look deeper into the data. They’re also really useful as a record of where sensors are installed.

To build a heat map, open the ‘create view’ menu (see below) and select Graph Heatmap.

  1. A new, empty view will open up.
  2. Click on the title of the box to change its name. You can now re name the Graph Heatmap.
  3. Upload a plan (PNG, JPG, GIF, EPS) by dropping the image on the hot spot.
  4. Physically pick up a kitten and identify it. If it isn’t labelled you will need to label it at this point.
  5. You can also make a note in the web service of the exact / descriptive location you plan to put the kitten in, by double clicking on the kitten and filling in the notes field (eg ‘under desk 1’).
  6. In the web service, drag each kitten to the right location on your image.
  7. You can now fix your real kittens in the right location.
  8. Your plan will automatically populate with data.

Select view


  1. Any images uploaded will be resized to 800 px wide
  2. It is possible to zoom in and out along the timeline by dragging and clicking your mouse to the left (to zoom out) or to the right (to zoom in)
  3. On any graph you can leave a note that relates to a point in time by double clicking on the x-axis
  4. PRO TIP: once you have set up this first view it is helpful to create a project called BACKUP and copy and paste this view into it. This will then keep the record of where you originally installed the sensors.

Once you have the first analytics view set up, there are a whole range of other views that can be used to interpret the data.
