The BarChart is a graphical component used for visual data representation in Displays/Draw. It can be configured to display dataset information in four different ways, each tailored to a specific context. This component is associated with a data source, such as a dataset table, from which it draws information.

Requirements
This graphical component requires a structured data source. This component is Portable, which means it will run both on Windows WPF displays and on Web Pages on any platform.
Configuration
- Go to Displays / Draw.
- On the Components Panel, select Charts, then BarChart.
- Click or drag-and-drop it on the Drawing area to use it.
- Double-click the object to open the configuration window.
Bar Chart Settings | |
|---|---|
Field | Description |
Control name | Specifies the name of the bar chart control. Used to identify the control within the application. |
Type | Defines the type of chart. The available options are:
|
Data Source | Indicates the data source for the chart, such as "Dataset.Table.Sales." This configuration item requires a structured data source for appropriate data visualization. |
Show horizontal labels 45° (WPF only) | When checked, displays horizontal labels at a 45-degree angle. This configuration is only available for WPF displays. |
Show value over bar | When checked, displays the values on top of each bar. |
Hide all zero series | When checked, hides series with all zero values. |
Show value labels 90° (WPF only) | When checked, displays value labels at a 90-degree angle. This configuration is only available for WPF displays. |
XAxis Width | Allows setting the width of the X-axis. |
Y Axis | Configures the Y-axis settings such as range, labels, auto-scaling, and format. |
Range | Sets the minimum and maximum range of the Y-axis. |
YAxis Height | Specifies the height of the Y-axis. |
Labels | Indicates the number of labels on the Y-axis. |
Auto Scale Y Axis | When checked, automatically scales the Y-axis based on the data. |
Format | Defines the format for displaying Y-axis values. Here, it's set to "N1," which is a numeric format with one decimal place. |
Grid Lines | Sets the color of the grid lines in the chart. |
Window | Specifies the color of the chart window. |
Labels | Sets the color of the labels in the chart. |
Data Items | Lists the data items (bars or lines) to be displayed in the chart. |
FieldTitle | Specifies the X-Axis Labels for the Data Item. This field must be filled with the title of a column containing the labels for each point in the series. |
FieldValue | Indicates the values to be used for each data point of the Data Item. This field must be filled with the title of a column containing the values for each point in the series (for example, if you have a column called Month, you must populate this field with 'Month'.) |
FieldColor | Defines the color of each bar in the Data Item series. This field must be filled with the title of a column containing textual RGB values in the format #AARRGGBB. |
Min | Sets the minimum value for the field. |
Max | Sets the maximum value for the field. |
Brush | Specifies the brush color used for the data items (bars). |
Runtime Execution
During runtime, the BarChart Control generates a series of bar graphs based on the provided dataset. When the runtime environment is initiated, the BarChart Control processes the dataset and displays the corresponding bar graphs. Users can interact with the bar graphs, which dynamically update as the underlying data changes. This allows for real-time visualization and analysis of data within the application, enabling users to monitor and interpret data trends effectively.
