Introduction
AXON Analyst's Contribution is Piano Analytics' data science powered feature specifically designed to draw insights efficiently from your data. Seamlessly integrated throughout Explorer, AXON Analyst's Contribution will do the heavy lifting so you can spend more time on higher-value tasks.
This feature will filter through all your data points to identify and quantify significant trends in your underlying data.
AXON Analyst's contribution power can be unlocked in two clicks: (1) simply activate Data Science mode by clicking on the light bulb icon while on a daily graph granularity in Explorer’s graph type selector then, if present, (2) click on an anomaly of your choice!
Availability
Analyses
The Contribution feature can be activated by clicking on any timeseries graph within Explorer. To do this, activate the anomaly detection feature by clicking on the ‘lightbulb’ icon on Explorer’s graph type selector, if anomalies are present in daily granularity, you can click on any anomaly of your choice to launch the contribution analysis.
Graph granularities
The contribution analysis is available on the daily graph granularity.
Metrics
The contribution analysis is available on any absolute metric of your choice (available on all metrics which are not ratios).
Concepts
Anomaly
Our built-in anomaly detection algorithm identifies how your data should evolve within a tolerance area. If your curve leaves this tolerance zone an anomaly will be identified and highlighted with the positive or negative anomaly icons.
Total Difference
The difference between where your data should lie (baseline - dotted line in the screenshot below) estimated by our algorithm and where your curve lies.
Property & property values
A property is an attribute of an event. Device, Traffic Source, Browser type are all properties. Properties have values, such as desktop, smartphone, tablet for the Device property.
Contribution
The share of the total difference attributed to a specific property value.
Interpretation of the results
Each bar chart reprensents one property.
The navy-blue bar represents the anomaly that we are looking to explain : the gap between expected data and actual data of the overall anomaly.
The light blue bars represent each property value’s share of contribution to the overall anomaly.
Note
We show the top 3 values for each property with the same sign as the overall anomaly. For exemple, if we are analysing a positive anomaly, we will show the top three positive values. Conversely, we will show the top three negative values for negative anomalies.Note
Although we only show the top 3 values for each property, the sum of all the property values' contributions is equal to the overall contribution (the navy-blue bar).Order of the results
Order of the bar charts
The charts are ranked in decreasing order on their top value's contribution. In the example below, the value 'Desktop' contributed to 95% of the total difference whereas the value France contributed 80%. Therefore, the properties 'device' and 'country' are ranked first and second in the list of bar charts.
Order of the properties
For each property, within the graphs, the values are ranked in decreasing order on their contribution to the overall anomaly.
Available visualisations
Two types of visualisations are available to view AXON Analyst's Contribution results:
Bar Charts:
This is the default visualisation, highlighting the contribution of each value towards the overall variation.
Line graphs:
The line graph can be activated using the visualisation toggle at the top right of each graph.
This visualisation puts into context the overall anomaly and each value's contribution around the data studied.
FAQ
Which properties are analysed?
The contribution will look for significant results in the following properties: device, traffic source, country, OS, Browser type, Level 2, Pages.
I can't find a specific property or property value
The contribution only shows properties and property values with significant results for a given anomaly.
I'm analysing segmented data, will the contribution look within that context?
The contribution will look for significant results by keeping in mind your analysis scope and segments.
A value contributed more than the overall anomaly - (A light blue bar is bigger than the navy blue bar)
Sometimes property elements work against each other: As an example imagine a positive anomaly of 100 visits above what was expected, where desktop traffic increased 120 visits and smartphone traffic decreased by 20 visits. In this case desktop traffic over-compensated for the decrease in smartphone traffic resulting in a positive anomaly of 100 visits. These are all valuable insights in order to understand what happened on a given date!
