User Interaction

User interaction adds to the appeal of any control. Keeping this in mind the ChartControl has been designed to be completely user - friendly and easily applicable for user interactions.

Chart data points 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 track a drag and drop of a chart point to a new location.

Interactive cursors let you position the cursors at a specific data point in a series and hint you on it's X and Y values via a horizontal and vertical line passing through the data point and intersecting the X and Y axis. These lines can be dragged around in order to position them at specific data points.

You can also use the up and down keys to move the horizontal cursor to the next vertically nearest point in the series or left and right keys to move the vertical cursor to the next horizontally nearest point in the series.

Tooltips can be displayed on hovering the mouse over Chart area, data points and other regions. Customization options are also available for the tooltip text.
