Gesture support for Visifire WP7 (Windows Phone 7) Charts

Chirag

Hi,

We showcased the use of Visfire in WP7 (Windows Phone 7) way back a year ago. Since then we concentrated much on increasing the chart types & also introduced gauges. Now that the adoption of WP7 is increasing we are getting serious on WP7. This release contains gesture support for WP7. It supports gestures like pinch-zoom, panning and selection.

Embedded below is a short video showcasing gesture support in Visifire for WP7.

This release is just the beginning. Going forward, we are channelizing our energy to make the charting experience on WP7 even smoother & richer. Coming soon are:

  • Selection of a group of DataPoints
  • Tooltips on multi-touch
  • Controls optimized for resource constraint devices like phone
Give it a spin & let us know what you think. Download the latest release here.

Silverlight and WPF Enterprise Dashboard

somnath

Enterprise dashboards provide rich data visualization for analyzing data. A dashboard – for eg. sales dashboard is a vital tool for C-level executives, business managers and sales persons. This sales dashboard is a demo application using rich set of Visifire controls to analyze product wise monthly revenue of a fictitious company. It also shows sales conversion ratio showing how successful the sales team is in converting the leads to sales. Based on several parameters shown in the dashboard the decision makers can make informed decisions. 

This dashboard application is built based on MVVM pattern and best practices. MVVM follows three basic blocks called Model, View and ViewModel. The figure below shows basic blocks of the dashboard application.

Model: The Model is also called DataModel which contains business objects and model classes. It is independent of the View(UI).

View: The View contains visual elements displayed to the user and allows the user to interact with it.

ViewModel: The ViewModel represents the “Model of the View” which is also a mediator between View and the Model. It exposes the model’s data that is needed by the View.

In this Sales dashboard, the model represents business objects which include Model classes (Order and SalesConversion classes). View mainly represents user interface (XAML) and handles user interaction. “ProductWiseSalesView” contains chart controls to display product wise monthly revenue distribution, sales in volumes like sales conversion ratio, number of licenses sold with or without support and new licenses vs upgrades. The “ProductWiseSalesView” also contains two Gauge controls which displays annual revenue for a particular product. User interacts with the View. Content of the View is handled in the ViewModel through binding. The binding between View and ViewModel is done by setting ViewModel as the DataContext of the View. The ViewModel is derived from ModelBase class which in turn implements INotifyPropertyChanged interface to support DataBinding. Hence when ViewModel properties are changed, new changes are automatically reflected in the View.
