Charts

General information

Brick provide wide possibility of data visualization with different dashboards, they are:
  • bar plot for tracking changes over time or comparing different groups
  • box plot for showing distributions, identifying outliers or finding differences between categories
  • scatter plot for showing relationship between two variables and exploring patterns of this relationship
  • heatmap plot for visualizing concentration of values in two dimensions
  • histogram plot for showing distributions
  • line plot to visualize changes over time or to display data over numerical axis
  • pie chart to show parts of the whole
  • treemap for organizing hierarchical data
  • Gantt chart for planning and scheduling processes, based on time and resources needed
  • radar chart (the same as spider chart) to visualize multidimensional data

Brick Parameters

  • Plotting speed optimization
      • Choose this option if you want to build your plots more fast but will lose a bit in resolution.
  • Add a chart
      • To add a new
    • Diagram Type
        • Specify type of dashboard to plot on. There are: bar, box, scatter, heatmap, histogram, line, pie, treemap, gantt, radar.
    • Chart Name
        • A name for the chart
      Then, for different type of charts there are different parameters that are needed to be filled.

  • Open dashboard view
      • Shows all the plots that have been built. In this view it is possible to download a png file, zoom a plot, autoscale or reset axes.

Brick Inputs/Outputs

  • Inputs
      • Brick takes the data to plot

Example of usage

Let's consider the binary classification problem. The inverse target variable takes two values - survived (0) - good or non-event case / not-survived (1) - bad or event case. The general information about predictors is represented below:
  • passengerid (category) - ID of passenger
  • name (category) - Passenger's name
  • pclass (category) - Ticket class
  • sex (category) - Gender
  • age (numeric) - Age in years
  • sibsp (numeric) - Number of siblings / spouses aboard the Titanic
  • parch (category) - Number of parents / children aboard the Titanic
  • ticket (category) - Ticket number
  • fare (numeric) - Passenger fare
  • cabin (category) - Cabin number
  • embarked (category) - Port of Embarkation
Let’s move to some visualizations.
  1. First one will be scatter plot with settings listed below with result:

  1. We will show a bar chart where on x axis we put sex column and for y axis survived column.

  1. We build a pie chart for pclass:

  1. We will build a box plot for fare column

  1. We will show how to build a heatmap plot:

  1. To plot a Treemap chart we need to create some synthetic data, the data and chart build will be presented below:

  1. Next example will be associated with a radar chart, for this example we also need to create some synthetic data. Let’s visualize results we have:
