Visualizations let you present data so that your app's users can interpret and explore it. For example, a bar chart that compares sales numbers for different regions, or a table with precise values for the same data. Good visualizations help you quickly and accurately interpret displayed data.
Visualizations are easy to add and customize. They can take the form of charts, such as bar charts, pie charts, tables, gauges, or treemaps. Each chart type has unique functionality. In the Qlik Sense Dev Hub, you can create custom objects. Qlik Sense automatically highlights items associated with your selections so you can drill-down and filter.
You need to understand your data in order to design an effective visualization with a clear purpose. Ask yourself the following:
- What kind of data is it? Nominal, ordinal, interval, or ratio data?
- How do different parts of the data relate to each other?
- Can you organize the data in a way that makes it easy for you to create your visualizations?
- What do you want to communicate with your data?
- Are there dimensions or measures you will want to reuse in multiple visualizations?
You also need to understand your data in terms of fields, dimensions, and measures. These affect how your data is used in your visualizations.

Each visualization type has a specific goal. You need to think about the purpose of your visualization, and pick a visualization type that lets you explore your data for that purpose effectively.
For example: You want to show how a measure, quarterly sales, behaves over time. You should create a line chart, because one of its strengths is displaying how measure values change over time.
Create visualizations with assistance from Insight Advisor
When building an app, you may know what questions you to try and answer, but not the combination of data and visualizations that will help you discover it.. Insight Advisor Search, Insight Advisor Analysis Types, and Insight Advisor chart suggestions can help guide you in creating visualizations.
Insight Advisor search based analysis can be accessed by clicking Discovery or entering a question in the search box. Insight Advisor Search and Insight Advisor Analysis Types can be accessed by clicking Insight Advisor in the sheet. You can also access Insight Advisor Search by entering a question in the search box. With Insight Advisor Search, Qlik Sense can analyze your data and create visualizations based on your search terms or selections. You can then pick which visualizations you want to add to your sheet. Insight Advisor Analysis Types allows you to pick the analysis type you want to see with the fields you want used . Insight Advisor then creates analyses to your specifications. For more information, see Creating visualizations with Insight Advisor.
Insight Advisor chart suggestions helps you build visualization quickly. By dragging a field onto sheet from your assets panel and then dragging additional fields onto the first field, Qlik Sense will create a suggested visualization for that combination of fields. Chart suggestions include a focused selection of chart properties you can adjust. If you want to do further adjustments, you can turn off chart suggestions for that visualization and have access to the full range of chart properties. For more information, see Creating visualizations using Insight Advisor chart suggestions.
As you create your visualizations, you can modify them to improve how data is displayed and highlighted within the sheet. You can also change the data, or switch the visualization type.
