This section describes the ChartDirector Zooming and Scrolling Framework for creating zooming and scrollable charts.
Description of the ChartDirector Zooming and Scroll Framework for Windows applications.
This sample program demonstrates a simple zoomable and scrollable chart with tooltips, using mouse click and drag to control zooming and scrolling.
In addition to using mouse click and drag, this example demonstrates using a scroll bar for scrolling, and mouse wheel for zooming. It also includes a track cursor that updates the legend dynamically to display the data values as the mouse cursor moves over the chart.
This example extends Zooming and Scrolling with Track Line (1) (Windows) by adding two date picker controls. The user can use them to change the start and end dates of the chart. Conversely, if the start and end dates of the chart are changed by other means (such as using mouse drag to scroll/zoom, mouse wheel or using the scroll bar), the date picker controls will be updated.
This example demonstrates zooming and scrolling in both horizontal and vertical directions. In addition to using mouse click and drag, this example demonstrates using a slider and the mouse wheel to control zooming. There is also a "navigation pad" which can be thought as a representation of the view port. You can drag the pad to move the view port around (that is, to perform 2D scrolling). This example also includes a crosshair track cursor with dynamic labels on the x-axis and y-axis showing the mouse cursor position, and an image map for data point tooltips.

Besides using mouse click and drag for zooming and scrolling, this example has buttons for jumping immediately to display data for the last 30 days, last 90 days, last year or all time. There are check boxes to select the data series to plot, and an update button to immediately update the chart. In addition, the chart includes a track cursor that updates the legend dynamically to display the data values as the mouse cursor moves over the chart.
