Charts within spreadsheets can display the data from an assigned cell range within the spreadsheet.
Any modifications made to the data within the spreadsheet will also be reflected in the assigned chart.
The following example shows how to create a chart assigned to some cell ranges within a spreadsheet document:

<source lang="oobas">
Dim Doc As Object
Dim Charts As Object
Dim Chart as Object
Dim Rect As New com.sun.star.awt.Rectangle
Dim RangeAddress(0) As New com.sun.star.table.CellRangeAddress

Doc = ThisComponent
Charts = Doc.Sheets(0).Charts

Rect.X = 8000
Rect.Y = 1000
Rect.Width = 10000
Rect.Height = 7000
RangeAddress(0).Sheet = 0
RangeAddress(0).StartColumn = 0
RangeAddress(0).StartRow = 0
RangeAddress(0).EndColumn = 2
RangeAddress(0).EndRow = 12

Charts.addNewByName("MyChart", Rect, RangeAddress(), True, True)
</source>

Although the code used in the example may appear to be complex, the central processes are limited to three lines. The first central line creates the <tt>Doc</tt> document variable, which references the current spreadsheet document (<tt>Doc</tt> line = <tt>StarDesktop.CurrentComponent</tt>). The code used in the example then creates a list containing all charts of the first spreadsheet (<tt>Charts</tt> line = <tt>Doc.Sheets(0).Charts</tt>). Finally, in the last line, a new chart is added to this list using the <tt>addNewByName</tt> method. This new chart is then visible to the user. The variable <tt>RangeAddress</tt> determines the assigned cell range whose data will be displayed within the chart. The variable <tt>Rect</tt> determines the position and size of the chart within the first sheet in the spreadsheet document.

The previous example creates a bar chart. If a different chart type is needed, then the bar chart must be explicitly replaced:

<source lang="oobas">
Chart = Charts.getByName("MyChart").embeddedObject
Chart.Diagram = Chart.createInstance("com.sun.star.chart.LineDiagram")
</source>

The first line defines the corresponding chart object. The second line replaces the current chart with a new one — in this example, a line chart.

{{Documentation/VBAnote|In Microsoft Excel, a distinction is made between charts which have been inserted as a separate page in a Microsoft Excel document and charts which are embedded in a table page. Correspondingly, two different access methods are defined there for charts. This distinction is not made in {{OOo}} Basic, because charts in {{OOo}} Calc are always created as embedded objects of a table page. The charts are always accessed using the <tt>Charts</tt> list of the associated <tt>Sheet</tt> object.}}
