Bar Chart

Component Palette Icon:


The Bar Chart is a very easy-to-use chart that provides a familiar bar representation of any numeric values. That is, the height of the bars is determined by some numeric value in the underlying dataset. It is often configured to display as a category chart. A category chart is a chart whose X-values are categories (strings, names, groupings, etc) rather than numeric values (numbers, dates).

Like most chart components (other than the Easy Chart), the Data property drives the chart. The first column in the Data dataset defines the names of the categories. The rest of the columns define the values for each of the series (if there is more than one series per category), and thus should be numeric.


If your data is 'turned on its side', meaning that the columns define the categories and rows define the series, then set the Extract Order to "By Column".

Extension Functions


  • Description

    • Provides a chance to override the color of each bar. Can be used to have bar colors changed based upon bar value. Returning the value None will use the default bar color for the series.
  • Parameters

    • Component self - A reference to the component that is invoking this function.

    • int series - The series index for this bar.

    • int category - The category index for this bar.

    • int value - The value (a number) of this bar.

    • Color defaultColor - The color that the bar would be if this function wasn't invoked.

  • Return

    • Color
  • Scope

    • Client
