Horizon Chart

Version 1.0

 

Description

The Horizon Chart is a data visualization technique that displays time-series data in a compact and layered format, improving readability and enabling comparison of multiple datasets over time.

Dependencies

For optimal performance and accurate graphs, please install the Mapping Toolbox .

Syntax

• horizonChart creates a Horizon Chart x-axis data and y-axis data for each slice
• horizonChart(x, y) creates a horizon chart with x an y data and NumBands = 2 i.e. in each of the slices, the data is divided into 2 regions - one above the baseline and one below the baseline
• horizonChart(x, y, numBands) creates a horizon chart with x and y data with number of bands = numBands. Number of Bands is the number of sections that the data is divided into
• horizonChart(__ , Name, Value) specifies additional options for the horizon chart using one or more name-value pair arguments. Specify the options after all other input arguments.

Name-Value Pair Arguments/Properties

• XData XData is a 2-D matrix where each column specifies the x-coordinate of data to be displayed in an individual slice of the of the chart.
  XData can also be a 1-D matrix which can denote the common x-values for each of the subcharts/ individual slices.
• YData YData is a 2-D matrix where each column specifies the y-coordinate of data to be displayed in an individual slice of the chart.
• Labels A list of labels for each of the slices in the chart
• NumBands Number of Bands/Segments to divide the Horizon chart

Stylistic Name-Value Pair Arguments/Properties

• ColorAboveBaseline It is used to determine color gradient that bands above the baseline are shaded with.
• ColorBelowBaseline It is used to determine color gradient that bands below the baseline are shaded with
• XLabel Label for X-Axis
• YLabel Label for Y-Axis
• Title Title for the Horizon Chart

How to use it

n_stocks = 5;
[y_data, x_data, labels] = GenerateRandomData(n_stocks);

% Create a basic Horizon Chart with 5 Bands(Data is divided into 5 different segments)
basicHorizonChart = horizonChart(x_data, y_data, 5);
