Uncover the Shape of Your Data with Histograms

Stop guessing and see the true distribution of your process data. Histogram+ instantly visualizes the frequency of data points, revealing patterns, central tendencies, and outliers at a glance.

From Raw Data to Statistical Insight

Understand Data Distribution

  • Frequency Analysis: Instantly see how often different values occur within your dataset.
  • Supports All Data Types: Works with numbers, strings, booleans, and enumeration values.
  • Customizable Bins: Define the number of bins or let the symbol automatically calculate the optimal grouping.

Advanced Statistical Overlays

  • Display Percentiles: Overlay key statistical markers like P10, P50 (median), and P90 directly on the chart.
  • Bell Curve & Standard Deviation: Visualize the normal distribution curve and standard deviation lines for your data.
  • Multistate Limit Lines: Use multistate configurations to highlight target ranges or critical operating limits.

Seamless Integration & Export

  • One-Click Data Export: Download the raw or aggregated chart data to CSV or JSON for further analysis.
  • Live Data Connection: Works with PI Tags, AF Attributes, and custom PI Vision calculations.
  • Simple Configuration: All features are managed through an easy-to-use panel directly within PI Vision.

Identify Trends and Optimize Performance

Quality Control & SPC

Analyze the distribution of a key quality parameter to understand process capability and variability against spec limits.

Performance Monitoring

Track the distribution of equipment cycle times or asset performance to identify the most common operating states.

Process Optimization

Analyze a process variable's distribution to see if it's centered on its target, helping to reduce waste and improve efficiency.

Alarm Rationalization

Visualize the frequency of different alarm states or values to identify "chattering" alarms and optimize alarm limits.

Powerful Statistical Analysis, Simplified

Multistate Visualization

Apply color-coding to bars or display limit lines based on your multistate configuration.
