See tag usage as a bar or line chart

Last updated January 21, 20192 minute read

Combine the power of highlights on qualitative data with a quantitative visualization of your highlights as a bar chart or line chart.

In a project, click Analyze then Bar chart or Line chart.

Bar chart

The bar chart displays your selected metric (see below) as a snapshot at the current point in time. As you create new highlights in your project, the bar chart will be updated. It does not show historical data.

Line chart

The line chart shows historical data, displaying your selected metric over time, which can help you see changes in your data over time.

For example, if you’re collecting user feedback and tagging regularly, the line chart can help you keep track of increases or decreases in feature requests or customer satisfaction through automatic sentiment analysis.

Note: Data for the line chart is calculated every day at midnight UTC. This means the line chart will appear empty for new projects.

Filtering your data

To the right of the chart is the legend, which is also an interactive filter.

Click the Expand icon to expand a tag group, then click Select all to show bars or lines for all of the tags within the group. From here, you can also select or deselect individual groups or tags to show on the chart by clicking the checkbox next to each group or tag.

By default, the chart only displays data for each group of tags. The number on the chart is a ‘roll-up’, calculated by adding together all of the numbers from the tags inside the group.

Chart metrics

Dovetail’s charts can show three metrics, each of which give you a slightly different perspective on your data.

  • Highlights by tag. This shows the total count of highlights created on notes. For example, if you have 6 notes and across those notes you’ve added 14 highlights, this would show 14.
  • Notes by tag. This is very similar to highlights by tag however it will only count an highlight at most once per note. Using the example above, this would show 6 rather than 14.
  • Tagged text volume. This shows the total character count per highlight. If your data is customer interview transcripts or user feedback, this metric can be useful to help you get an understanding of how much importance the subject places on this topic.

Data visualization options

There are several toggles to change how your data is presented. These can be found near the top right of the chart, above the legend / filters.

  • Use color from tag / group. By default, chart colors come from a pre-determined array. This setting overrides that behavior and colors the lines or bars according to the actual color of your tag or group.
  • Use smoothed interpolation. Line chart only. This switches between ‘jagged’ lines and ‘curvy’ lines. This one’s great for taking nice screenshots!
  • Use square root Y axis. Line chart only. This switches between a linear axis and a square root axis. This improves readability with low volumes of data.
