# Available Data Science Charts

Version 10

Data science charts enable you to perform in-depth statistical analyses on your Domo data.

The following table lists the types of Data Science charts available in Domo. You can click a thumbnail image to see a larger image.

Description

Example

Scatter Plot chart

A standard Scatter Plot chart has two value scales, one on the vertical axis (or y-axis) and one on the horizontal axis (or x-axis). These values are treated as coordinates; for every x and y value pair, a single point is plotted on the chart. Points can be assigned into specific groups by including series data in the chart.

You can also create a Scatter Plot Time chart, in which you include timeline data instead of value data on the x-axis. In this case, all points are plotted on their appropriate date/time coordinates. The position of a point for a given date/time coordinate is still determined by its y coordinate value, however.

The first example shows a standard Scatter Plot chart. The second example shows a Scatter Plot Time chart.

As of our July 2017 release, the Scatter Plot chart has been updated and no longer aggregates data (which had the effect of lumping all data in a series into a single dot). If you want to use the old version of the chart, you can do so by selecting the Scatter Plot Legacy chart type.

Scatter Plot (Legacy) This is the version of the Scatter Plot used prior to our July 2016 release. It is preserved for backwards compatibility purposes; however, for new charts we recommend using the standard Scatter Plot chart. N/A

Bubble chart

Bubble charts are similar to Scatter Plot charts in that they have two value scales, and x and y coordinate pairs are plotted on the chart. Bubble charts are more complex than Scatter Plot charts in that they include an additional dimension—bubble size. Thus they require an additional DataSet column containing size values for each bubble. In the example at right, the y-axis measures employee salaries and the x-axis measures the average number of employees receiving those salaries. In addition, the size of each bubble represents the total percentage of the payroll for each department.

You can also create a Bubble Time chart, in which you include timeline data instead of value data on the x-axis. In this case, all bubbles are plotted on their appropriate date/time coordinates. The position of a point for a given date/time coordinate is still determined by its y coordinate value, however.

The first example shows a standard Bubble chart. The second example shows a Bubble Time chart.

As of our July 2017 release, you are no longer required to include series data in a Bubble chart, though this option is still available. If you want to use the old version of the chart, you can do so by selecting the Bubble Legacy chart type.

Bubble (Legacy) This is the version of the Bubble chart used prior to our July 2016 release. It is preserved for backwards compatibility purposes; however, for new charts we recommend using the standard Bubble chart. N/A

XY Line

An XY Line chart uses x and y coordinate pairs instead of date/time data to plot trendlines. Because of this mathematical plotting, there are not evenly spaced intervals between data points as there are in charts that use date/time data; therefore, these charts are useful for portraying trendlines with greater accuracy.

A basic XY line chart requires only two columns of data to draw the line, but you can also include a series column to show multiple lines. You can also add a line for a median value and specify lower and upper range values. Be aware that this chart type does not currently include algorithms to identify your median line and upper and lower ranges. You must identify these elements yourself in the DataSet you use to power the chart. However, you can use tools such as R and Python to help you identify these elements.

The screenshot shows an XY chart with a single trendline, median line, and upper and lower bounds set.

Predictive Modeling

A Predictive Modeling chart is essentially a Scatter Plot chart that includes a model fit line. If you want, you can also specify the upper and lower bounds of the model fit line.

Be aware that this chart type does not currently include algorithms to identify your model fit line and upper and lower bounds. You must identify these elements yourself in the DataSet you use to power the chart. However, you can use tools such as R and Python to help you identify these elements.

Forecasting

A Forecasting chart consists of a basic trendline for all data up until the current date/time, along with a forecast line showing predicted changes beyond the current date/time. You can optionally indicate the lower and upper bounds of the forecast line. If you want, you can even include a second forecast line with its own upper and lower bounds.

Be aware that this chart type does not currently include algorithms to create forecast line(s) and upper and lower bounds. This data must already be present in the DataSet you are using to power the chart. However, you can use tools such as R and Python to create these columns in your data source before bringing them into Domo.

Outliers

An Outliers chart is nearly identical to a basic Line chart but allows you to call out any points you deem to be outliers.

Be aware that this chart type does not currently include algorithms to identify outlier points. You must identify these points yourself in the DataSet you use to power the chart. However, you can use tools such as R and Python to help you identify these outliers.

Vertical Box Plot chart

Box Plot charts are commonly used to represent statistics and quality measurements. For any given category, at least five values are required in the DataSet. From these values, Domo derives a high value, a Q3 (Quartile 3) value, a median value, a Q2 (Quartile 2) value, and a low value. These values are plotted on the chart as a box and whisker plot, with the Q1, median, and Q3 values forming the box and the high and low values forming the "whiskers."

In a vertical Box Plot chart, values are represented on the vertical axis (or y-axis) and categories are represented on the horizontal axis (or x-axis) so the boxes stretch from top to bottom.

Horizontal Box Plot chart

Horizontal Box Plot charts are the same as vertical Box Plot charts, except that categories are represented on the vertical axis (or y-axis) and values are represented on the horizontal axis (or x-axis), so the boxes stretch from left to right rather than top to bottom.
