Bar Chart

Use a Bar Chart to compare categorical aggregate values. For example, a bar chart can be used to compare the amount/percentage of a population that attends various categorical events. In Qrvey, users can create Horizontal or Vertical Bar Charts.

Creating a Bar Chart​

Bar Charts are used when you want to present a single value and a single category. To create a Bar Chart, drag and drop a data field from the Data Panel onto either the corresponding shelf or the canvas.

In the case below, we wanted to show the quantities in different statuses of shipments. We dragged and dropped status as Category and Quantity as Value. The chart orientation was changed from the default horizontal to vertical and the colors were customized to show canceled (red), shipped (green), and on-hold (yellow) shipments at a glance.

If you have more than one category you’d like to visualize, you can use a Multiseries Bar Chart.

Styling the Bar Chart​

In the Configuration Panel on the right of the Chart Builder, you can style different aspects of your chart.

General​

The General section is available for all chart types, and the options vary depending on the chart selected. For more information on the options, see General Chart Settings.

Styles​

The Styles section enables you to control various visual elements of the charts, such as colors, labels, and more. It is available for most chart types, and the options vary depending on the chart selected. For a glossary of all styles, see Styles. Style options specific to this chart are listed below.

Color Type​

  • Single - all bars are the same color. 
    * **Color** - change the color of the bars.
  • By category - each bar is colored based on its category. 
    * **Theme** - set one of the predetermined themes for a more unified look of your charts.  
    * **Match colors across charts** - unify the colors of each categorical value throughout the page and application.

X-Axis​

  • Value Labels. Determines whether the value labels are displayed.
    • Label Rotation. Select how to display the labels. Options are horizontal (default), diagonal, and vertical. To set a custom rotation angle, click the Custom icon and enter the desired angle in increments of 15, up to 345. Use this option to avoid overlapping labels.
    • Skip Labels. Enables you to adjust how axes labels are displayed on the chart. Options are:
      • Auto (default). The system determines how to display the chart labels.
      • All. Skip all labels, so that none are displayed.
      • None. Do not skip any labels, so that all labels are displayed. Note that some values may overlap.
      • All but first and last. Skip all labels except the first and last values.
      • Custom. Enter a custom number of labels to skip.
  • Typeface. Select the typeface of the labels.
  • Weight. Select the font weight of the labels.
  • Size. Select the font size of the labels.
  • Font Color. Select the font color of the labels.
  • Format - set the format of the values choosing between Default, Abbreviated, Decimal (set the number of decimal points), Currency (choose the currency from the drop-down menu and set the number of decimal points), Percentage (set the number of decimal points), Scientific. Values can also be formatted from the Values column pill.
  • Scale Type - the default scale type is Linear; however, a linear scale is not appropriate for data that is spread over a wide range. Use the Logarithmic scale to display numerical data over a wide range of values in a compact way.
  • Min Range - set the minimum value for the axis.
  • Max Range - set the maximum value for the axis.
  • Steps - Depending on how wide the axis range is, the default configuration could display a lot of tick marks, making it hard to read or analyze the chart. Intervals are set to Auto by default, meaning the chart will calculate the appropriate intervals based on the axis scale range and the dataset values. In the example below, we set the step to 100 units, so the chart will display a tick mark every 100 units starting from 0, resulting in only 3 tick marks. bar-chart It’s important to keep in mind that when the axis range is vast (e.g., 0 - 10,000,000), setting the “Steps” option to 1 will create 10 million tick marks, causing performance issues on the chart and probably blocking the browser. To avoid this situation, the chart will ignore the defined value and fall back to automatic mode.

Y-Axis​

Similar to X-Axis, with the following additional options:

  • Bar Width. Select the width of the bar. The default setting is Auto, meaning the system adjusts the percentage to what it sees as most adequate considering the size of the chart. If the width is set to 100%, the bars use up all of the chart’s space and there’s no gap left between them. Choose a width percentage other than 0 to decide the width of each bar and the gap between them. Setting the percentage to 0 will return the mode to automatic.
  • Data Labels. Select whether to display data values from the dataset column assigned to the Value shelf.
  • Borders. Select whether to display borders around the Data Labels.
  • Shading. Select whether to shade the remaining space between the actual value and the top of the bar.
  • Offset. Determines the offset of the chart. Select whether to configure a manual offset as a Percentage or in Pixels, and enter the desired values in the Left and Top/Bottom fields. To enable the platform to automatically manage the offsets, click Reset to Default to set the values under Left and Top/Bottom to Auto.

Sorting​

Like all XY Charts, you can sort by either the category or aggregated values from the column pills. If the column is not included in the chart, go to the Sorting section of the Configuration Panel and pick your desired column from the dropdown, and select the sorting direction.

For more information, see Sorting.

Layers​

Add a Trend Line or a Reference Line to your chart to allow users to visually compare the data against some set trend or reference value.

Format​

The Small Multiples feature is available in all XY Charts. You can apply Conditional Formatting to your Bar Chart.

Filters​

You can also add Filters to your data by expanding the Filters section in the configuration panel or by clicking on the Filters button in the toolbar above the canvas. Filters that are created in the Chart Builder are hidden from End Users. These types of filters can’t be edited or interacted with in the view mode. For more information, see Filters.
