Overall
Scatter-plots are used when you want to directly compare two values to one another – particularly when neither of the values make up a sequence (such as an asset number, time or relationship).
They allow you to see clusters, patterns and correlations between the values, which can lead into new insights into how properties interact with one-another.
If you have more than two dimensions of data to compare, it’s possible to create 3D scatter plots. However, because they are often quite difficult to read and can’t scale any further than 3 dimensions, we usually suggest using polar coordinate charts instead.
Example
In this example, we are looking at our roof supports on our longwall mine.
Each support has two large hydraulic cylinders that push up against the roof of the mine to ensure it doesn’t fall.
The pressure inside those cylinders is monitored. The pressures should ideally be very similar – a large difference between the two can indicate a leak or other major failure.
Scatter plots also give you some additional opportunities – you can use the colour, size and shape of the scatter-plot markers to indicate other variables, or to tell your users if values are in their expected range.
You can find this example on our longwall mine demo site.
