Interactive Elements

User interaction adds to the appeal of any control. Keeping this in mind the Chart Control has been designed to be completely user-friendly and supports several user interaction elements.

The data points on the chart can be auto-highlighted on mouse hover. The highlight color for such elements can be customized.

Using the Mouse events fired by the chart you can drag and drop a data point to a new location on the chart.

The Interactive Cursor feature lets you position the cursors at a specific data point in a series. The X and Y coordinates of this point can be read using the horizontal and vertical line passing through the data point and intersecting the X and Y axis respectively. These lines can be dragged and positioned specific data points.

You can also use the up and down arrow-keys to move the horizontal cursor, and the left and right arrow-keys to move the vertical cursor.

ToolTips can be displayed on mouse hover over chart area, data points and other regions. Customization options are also available for the tool tip text.
