CBCGPChartTextObject

Detailed Description

The CBCGPChartTextObject implements the functionality of a textual Chart Object.

The following picture illustrates some text objects you can add:

• a text object within a rounded rectangle with shadow
• a text object with connector
• a text within rectangle

The text box, font and all other parameters are fully customizable (use CBCGPChartObject::m_format to format a text object).

Call SetRoundedShape() to set rounded corners, SetShadow() to display a shadow under text box, SetDrawConnector() to drop a line with connector from the text box to a point on the diagram (you have to set CBCGPChartObject::CM_CHART_VALUE_DIST_ANGLE coordinate mode for this purpose).

You can use CBCGPChartVisualObject::AddChartTextObject to add a text object to a Chart.

The following shows another way to construct and add a text object:

Copy

CBCGPChartVisualObject* pChart = m_wndChart.GetChart();

// create a text object at coordinates X = 2; Y = 3; with distance from (X,Y) point 30 pixels, angle -45 degrees

m_pTextObjectGreen = new CBCGPChartTextObject(pChart, _T("Green Area"), 2, 3, m_brText1, m_brFillText1, m_brLine3, 30, -45, TRUE /*draw connector*/);

// add the object to parent Chart

pChart->AddChartObject(m_pTextObjectGreen);

You can also use the base CBCGPChartObject class and specify its m_strText property, but you won't be able to set rounded corners, display shadow and connector.
