Charts presentation style will display as many reasonably-sized charts as possible on each device size. By default, each chart is of size “small”, which means that the chart will use 1/3 of the available space in each dimension on large screens.

On medium-sized devices, the charts will use 1/2 of the available space.

The smallest devices will display only one chart at a time.

The user is able to change the size of the charts using the context menu in the top right corner of each chart. “Large” is only available on large devices, and “Medium” is only available on moderately sized devices and tablets.

The developer is also capable of specifying the default size for each chart by adding the keywords “medium” or “large”. Suppose that the Orders controller has manually specified charts matching those that have been automatically created. The highlighted tags below will specify the default sizes for those charts.

Upon regenerating the app and refreshing the page, notice that the default sizes have been applied. The first chart is of “medium” size and now takes 2/3s of the screen on large devices.

The “large” fourth chart takes the whole screen.

Every chart that has been automatically or manually defined will display a title. This title will be composed using the row, column, and value fields and their properties that have been specified for the chart. For example, suppose we create a curved line chart on Orders page of the Northwind sample app that uses OrderDate for rows, EmployeeID for columns, and the sum of Freight for values.

The data for the chart can be seen below.

The title states that the chart shows top three “Employee Last Name”. The value is the sum of “Freight” and the rows are grouped by “Order Date”. While the title may reveal all the necessary information, the title can be better. Let’s manually specify the title by adding the following tag. Note that the tags do not need to be on any particular data field, as long as the correct pivot ID is specified. Open the Project Designer. In the Project Explorer, switch to the Controllers tab and double-click on Orders / Views / grid1 / EmployeeID data field node.

Add the highlighted tag:

Save the data field and regenerate the app. When the page comes up in your browser, navigate to the Orders page. Note that the new title has been applied.

The new title will also be displayed above the chart data.

By default, the axes do not have a title applied. One can use the “haxistitle” or “vaxistitle” properties to manually specify a title for the horizontal or vertical axis, respectively. Let’s specify the following axis titles:

The new chart will display the specified labels on each axis.

The chart data will not be changed.
