Interacting with the Chart

You can interact with the chart as it is running to examine data more closely or visually isolate a part of the chart. The interactions described here affect the chart displayed inside the ChartArea; other chart elements like the header are not affected.

ComponentOne Chart provides users with 2 different mechanisms for zooming the chart: Graphics zoom and Axis zoom. Performing a Graphics zoom enlarges the selected area of a chart, while not necessarily showing the axes. Performing an Axis zoom changes the minimum and maximum data values to those selected, and redraws only that data with axes.

Special Notes

· The keyboard/mouse combinations that perform the different interactions can be changed or removed by a programmer. The interactions described here may not be enabled for your chart.

· Scaling, moving, or graphics zooming the chart sets the PlotArea margin properties, so the chart will not automatically control margins anymore when other chart properties change.

1. Press CTRL, and hold down both mouse buttons (or middle button on 3-button mouse).

2. Move the mouse down to increase chart size, or move the mouse up to decrease chart size.

To Move the Chart:

To Rotate the Chart (Bar/Pie Charts Displaying 3D Effect Only):

2. Move mouse up or down to change the 3D inclination

3. On bar charts, you can also move mouse left or right to change the 3D rotation angle

To Reset to Automatic Scale and Position:

Press the “r” key to remove all scaling, moving, and zooming effects; chart regains control of PlotArea margins.
