    User Scenarios

    Set Custom Labels for X-Axis

    Using LabelField property, you can display a custom label for the X-axis, that is, the Category Field. For example, in the following chart, the default labels for X-Axis show Ship Names since the Category Field is bound to [ShipName]
    The chart binds to the 'Invoices' table of the Nwind.db Sqlite provider.

    Labels for X Axis

    You can customize the X-Axis labels of the chart as follows.

    1. From the Report Explorer, go to Chart > Plot Area and select X Axis - [Plot1].
    2. In the Properties window, go to Labels > LabelField property.
    3. Enter the following custom label in the LabelField property to view 'City' along with 'Ship Name'.
           
           =Fields!ShipName.Value + " , " + Fields!City.Value
    4. Preview the report.

    The below image shows how the X-Axis labels show customized labels.

    Customized X-Axis Labels

    Set Position of Axis

    A set of four properties for the X and Y axes - Width, MaxWidth, Height, and MaxHeight help users to control the position of the axes by specifying the height and width values for the X and Y axes, and their corresponding maximum values up to which the axes can grow. If the length of the data labels and titles in a chart exceeds the specified maximum height and width, labels are clipped-off. These properties are used to align a chart with the other controls or data regions. 

    Note that when a user does not specify these properties, the height and width for the chart axes are calculated automatically depending on the bound data. If the user wants to set the exact Y-axis position, the 'Width' and 'MaxWidth' properties should be set to one value. This value should be found by the user at design time.

    Let us see how to align the vertical axis of a Chart data region relative to a Textbox control on the same page. The below image shows how the chart appears with the following properties set for the vertical axis.



    Chart Y-Axis Position-Default

    The steps to set the Y-Axis position of the chart are as follows.

    1. From the Report Explorer, go to Chart > Plot Area and select Y Axis - [Plot1].
    2. In the Properties window, go to Appearance > Width property and enter a suitable value.
      In our case, 30% aligns the Y-Axis with the TextBox control.
    3. Preview the report.

    The below image shows how the vertical axis of the chart is aligned with the textbox after the 'Width' property is set to a suitable value observed at the design time:
