Hello Vinay,

Most of your requirements can be met with Visiblox, here they are in order:

1. Highlighting a selected area series is possible with the free component by using a LineSeries with the ShowArea property set to true and either programatically changing the IsSelected property (or by allowing the user to select one or multiple series at a time).

Selecting just an area within the spike is not possible I'm afraid though as the whole area is rendered as a Path: either the whole thing can be selected or nothing.

2. The width and height of the Chart can be displayed as it is a Control and as such, has Width and Height properties.

3. Labels can be customized on the Axis: they can be styled and the format string can be changed. A customized label can also be added by adding it to the AdditionalLabels collection on an axis.

4. Gridlines can be turned on or off through the ShowGridline property on an axis.

5. X and Y coordinates can be displayed for data points either by turning on the tooltips on a series (by setting IsTooltipEnabled to true), using a Crosshair behaviour or creating a custom template for data points using the TemplatedSeries in the premium version.

6. Zooming in and out comes out of the box. See e.g. the line series example and zoom in by selecting an area on the chart and double click to zoom out.

Summing it up, almost all of your the requirements can be implemented using the free version of Visiblox charts. If you want to display the X and Y coordinates as part of the data point template, you would need to use TemplatedSeries in the premium version.

You can immediately get started evaluating the component by downloading the free version.
