  • In pie chart, exploded pie slice was animating each time on real-time update.

New in Visifire 3.0.0 Alpha (Nov 20, 2009)

  • Boasts of drastic performance improvements in Realtime Update.
  • For eg. A line chart in Visifire 2.x with 15,000 DataPoints took 40 secs to update in realtime, whereas in Visifire 3.0 it takes only 3 secs. Internally Visifire 2.x re-drew charts during Realtime Update.

As of now this performance enhancement has been done only for the chart types: Column, Line, Bar, CandleStick, Stock, Bubble, Scatter, Stacked Column & Stacked Bar. Same enhancements for other chart types will follow soon.
  • Animated updates - Once you change the value of DataPoint the chart updates to the new state with animation.
  • In this release animated updates is implemented for all chart types excluding Stock & CandleStick.

  • Label placement algorithm for StackedColumn, StackedBar and StackedArea charts has been improved.

New in Visifire 2.2.9 Beta (Oct 9, 2009)

Please check documentation for more detail.
  • MaxWidth and MaxHeight properties have been introduced in Legend. Now you will be able to set the maximum width and height of Legend.
  • Now LabelAngle property will be applicable for Point and Bubble charts also.
  • By default Legend will be disabled for Pie/Doughnut/StreamLineFunnel/SectionFunnel charts. You can enable Legend by setting ShowInLegend property in DataSeries.
  • For Pie/Doughnut/StreamLineFunnel/SectionFunnel, the default value for LabelText property will be #AxisXLabel,#YValue.
  • If LabelStyle property is set in DataSeries/DataPoint, auto placement for DataPoint labels will not work.

  • Fix for the following bug:
  • ZIndex property of DataSeries was not behaving as expected on real-time update.
  • Enhancements:
  • New property ScrollBarScale has been introduced at Axis element. ScrollBarScale sets the size of ScrollBar Thumb. For example, if ScrollBarScale is set to 0.5, width of ScrollBar Thumb will be half of the ScrollBar width which in turn increases the PlotArea width to double the actual width of PlotArea. It takes values from 0.1 to 1.
  • In Pie/Doughnut chart, if DataPoint has YValue property set to 0, label will appear for that DataPoint.
  • Now Rows property is dependent upon Angle property in AxisLabels.

New in Visifire 2.2.4 Beta (Jul 17, 2009)

  • In Area, StackedArea and StackedArea100 Charts, If Mouse event was attached to DataSeries or DataPoints, event was fired only on Markers.

  • ScrollBarOffset property could have been set only at the first time render.
  • In WPF, FlowDirection property didn’t behave as expected.
  • Removing the chart from the UIElement took longer time. Now it has been optimized.

New in Visifire 2.2.0 Beta 4 (Apr 10, 2009)

  • Contains fixes for the following bugs:
  • For DateTime Axis XValue property of a DataPoint was not formatted according to the culture used by current thread.
  • ScrollBarOffset didn’t return correct value if ScrollBar position was changed manually using mouse.
  • If Line, Point or Bubble charts are combined, some of the DataSeries went missing, when similar chart types are not grouped together.
  • Enhancements:
  • Events for MouseLeftButtonDown and MouseLeftButtonUp on PlotArea, are provided. Event arguments will provide XValue for the corresponding point. So, one should be able to find out the selected region and DataPoints within by using XValue.
  • Once the chart renders completely, Rendered event fires. As soon as chart is fully rendered and DataPoints are visible on the screen only then the Rendered event of the chart will be fired. Please note that Rendered Event does not wait for the Animation to be complete.

  • Chart performance has been optimized by partially updating the properties - MarkerColor, MarkerBorderThickness & MarkerBorderColor for the elements - DataPoint & DataSeries.

New in Visifire 2.0.6 Beta (Jan 3, 2009)

  • ToolTip can be customized. Properties like FontColor, Size, Background etc. can be defined by user. Style for ToolTip can be defined in chart XAML or in a custom theme file. As this feature warranted some code inclusion, the size of .xap has grown from 199KB to 203KB.

  • Visifire 2.0 follows the best practices laid down by Microsoft for component development.
  • In Visifire 2.0 all properties are dependency properties.
  • Dependency properties provide a way to compute the value of a property based on the value of other inputs.
  • Visifire works in WPF too - Visifire 2.0 boasts of multi-targeting feature. A single API to draw charts in Silverlight or WPF or WPF Browser Application. Yes, its true, you can start using Visifire in your desktop applications also.
  • Realtime Update - Any property of Visifire charts can be updated in realtime. No need to redraw the chart. Visifire1.x supported realtime update through Javascript, but not from managed code. We learnt that Visifire is being extensively used in managed code & updating charts in realtime is one of the most coveted feature. Hence, we implemented it. Real time update is showcased both in Chart Designer & Gallery.
  • Scrollable Charts - The name says it all. You can scroll the datapoints inside the charts. All chart types in the Gallery have an example showcasing this feature.
  • Styling - Visifire 2.0 charts can be styled. If you want to make the charts look the way you want & still harness the flexibility of Visifire, you can do so by styling the charts globally.
  • Editable in Blend - Designing requires a good Design Tool. It is true even for Silverlight Apps & that’s why Microsoft has Expression Blend. Visifire charts can now be designed in Microsoft Expression Blend.
  • Elegant Animation - Currently Visifire2.0 contains only one animation per chart type. The same animation doesn’t look good for all chart types. Hence, for every chart type a specific animation has been handpicked & polished to perfection.

New in Visifire 1.5.5 (Nov 6, 2008)

  • Chart type StackedArea100 crashed on setting YValue = 0 for any DataPoint.
  • In DataPoint, the property MarkerEnabled was being taken true for both boolean values.
  • ToolTip and Events were not working with 3D Chart if AnimationType = Type4 and no. of DataPoint > 900.
  • Pie and Doughnut Charts threw exception on MouseOver event with Href being set.
  • ShadowEnabled threw exception when chart is drawn from managed code.
  • Improved Axis Label Placement.

New in Visifire 1.5.4 (Oct 30, 2008)

  • Bug fixes:
  • Chart went blank if the no. of data points were more than 200.
  • Tooltips disappeared & JS events did not work after v1.5.2 internal release. (An emergency release - v1.5.3 - was done with the fix.)

  • Charts flickered when updated from JS.
  • Enhancements:
  • Visifire’s “Auto Label Skip” feature can be enabled by setting Interval = “0″. This feature is helpful when there are high no. of datapoints where in Labels are skipped at regular intervals to avoid overlapping. Eg.

New in Visifire 1.5.1 (Oct 16, 2008)

New in Visifire 1.1.2 (Sep 10, 2008)

  • Now you can set the background color of the silverlight plug-in while creating the visifire charts object. For example, var chart = new Visifire( ‘Visifire.xap’, ’slPlugin1′, 500, 300, ‘transparent’); Here ’slPlugin1′ is the ID of the silverlight control and it is optional. The last parameter in the constructor is the color which is again optional with default set to ‘white’.
  • To make the plug-in background transparent, you’ll have to set the windowless state to ‘true’ using function: chart.setWindowlessState(true).

New in Visifire 1.1.1 (Aug 8, 2008)

  • This release contains a new function added in the Visifire.js.

New in Visifire 1.0.15 Beta (Jul 24, 2008)

  • AxisLabels will not be skipped if they have been provided in the DataPoints. Previously the interval of the labels would be dependent on the interval of the axis.

  • Improved memory management to reduce the memory usage.
