Line Chart

With data visualization, you get a visual summary of information; with charts and graphs, it's easier to identify patterns and trends than looking through thousands of rows in a dataset. Along with the bar chart, the line chart is the most popular one.

Line charts are mostly used for numerical and time-series data; to track changes and trends over time, to display forecast data and uncertainty, to identify relationships between 2 or more variables, etc.

In Graphite, a line chart can have more axes like a bar chart: one x-axis (Category) and several y-axes (Series). Also, there are 4 types of lines: basic line, curved line, stacked line, and step line. Sometimes there is a need to put many lines onto a single line chart. But be careful: if the lines are similar, it will be difficult to see the details and differences in the chart. On the other hand, if the lines are well-separated, you can plot all the Series you want to track.

Follow these simple steps:

  1. Open or Create a notebook
  2. Select New Visualization
  3. Select a Dataset for your bar chart
  4. Select Combination Graph
  5. Choose your Category
  6. Choose one or multiple Series; select the type of the line (additionally, you can change its color).
  7. Select Save

Collect data and dig into data visualization. With line charts, you can provide a quick analysis of your data. Enjoy! 🙂

Bar Chart

Graphs present data as clearly as possible. To be able to interpret the results of the graph, you need to understand the types of graphs you have to choose from. Also, it is important to identify what makes one type of graph more suitable for some situations than the alternatives. The most commonly used are bar and line charts.

Bar charts are mostly used for categorical data; compare things between different groups, compare quantity, frequency, or ratio of each category, etc. A bar chart can have more axes in Graphite: one x-axis (Category) and several y-axes (Series). Also, there are 3 types of bars: vertical bar, stacked bar, and step bar.

Follow these simple steps:

  1. Open or Create a notebook
  2. Select New Visualization
  3. Select a Dataset for your bar chart
  4. Select Combination Graph
  5. Choose your Category
  6. Choose one or multiple Series; you can change the type of the bar or its color.
  7. Select Save

Bar charts can be also used for time-series data. For example, you can track changes over time: suppose you work in a hospital and have a total number of patients admitted by December 2014. Through the height of the bar chart, we can see the differences between the days: on which day most patients were admitted, which days had approximately the same number of patients, etc.

We briefly went through the basics of the bar chart, now it's your turn to create some visualizations. Enjoy! 🙂

Be creative through Graphite Notebook

After we have gone through some basic steps, let's dive a little deeper into Graphite. In this example, we will use the dataset obtained from the Timeseries Forecasting model on the Daily admissions dataset and summarize the results with Graphite Notebook.

First, let's compare actual and predicted values by drawing a graph. The predicted line is keeping pace with the actual line; the model has done an excellent job! 🙂

Besides the main prediction of the target value, our Timeseries forecasting model also predicts the lower and upper values (the model predicts the range of values for every day in the future, the range between lower and upper value), so let's make a table with these values.

For better interpretation, let's visualize our table in a chart. You can see how all curves resemble each other, which is great!

This is just one example of how to use Graphite Notebook - we hope this notebook has inspired your creativity. Enjoy! 🙂

Data Visualization

After you have created your notebook, we will go through some basic visualization tools (in case you missed how to create one, click here).

Data visualization gives us a clear idea of what the information means by giving it visual context through maps or graphs. This makes the data more natural for the human mind to comprehend, making it easier to identify trends, patterns, and outliers within large data sets.

Follow these simple steps:

  1. Select New visualization
  2. Select a dataset; a CSV file you uploaded or a dataset obtained from a model you ran.
  3. Select Visualization Type. Depending on what you want, you can select:
    • Combination Graph
      1. Select Add category; represents the abscissa of the coordinate system.
      2. Select Add series; represents the ordinate of the coordinate system.
        With a wide range of colors, you can choose different types of chart lines.
    • Table
      1. Select Add column; create table from selected columns.
    • Pie Chart
      1. Select Add category
      2. Select Add series

You can create visualizations with different datasets - there is no restriction that all visualizations within a Notebook must be created from the same dataset. Once you make your notebook, you will realize its power. Through various visualizations, you will understand the nature of the data or even get an idea of ​​how to improve your business! 🙂

Create your first Graphite Notebook

Your boss asked you to prepare a report or a presentation or do you just want to summarize your results? With Graphite, everything is possible! The main idea behind Graphite Notebook is to do your own Data Storytelling; create various visualization with detailed descriptions, plot model results for better understanding, etc.

Follow these simple steps:

  1. Select Notebooks
  2. Select Create New
  3. Name your notebook. Additionally, you can add a description to your notebook. Also, you can select an existing tag (to connect your notebook with datasets and models) or create a new one.

You can now easily add and delete different text and visualization blocks (more about visualization). If you are not satisfied with the block position, you can easily move it. To speed things up, you can even clone each block. Your first Notebook is created and ready for exploring.

The idea is to be as creative as you want - you adapt the whole notebook to yourself and your needs. Not all visualizations are always understandable to everyone - by using the Graphite Notebook, you can create visualizations of your choice, so that it is adequate to you. 🙂
