somnath

Hi,

This release contains fix for the following bugs:

  • In a Line chart if MovingMarkerEnabled property was set to true for a DataSeries, moving-marker was visible over the first DataPoint. Instead it should be visible only if mouse enters inside the PlotArea.
  • Axis was misaligned in a chart with very less height if Title property was set for it.

Enhancements:

  1. Visifire is now compatible with Silverlight 3

Bug Fixes:

  1. Interval was getting set as 1 for values ranging within 0 to 1 while it should be less than 1.
  2. In some extreme cases Column Chart DataPoints were not getting aligned properly.

Visifire 2.2.3 beta 2 Released!

somnath

Hi,

This release contains few bug fixes and a new feature. We have implemented DataPointWidth property in Chart. Now you will be able to control the width of a Column/Bar by setting the DataPointWidth property in Chart. Width of DataPoint is calculated as a percentage of PlotArea viewport width.

Bug Fixes:

  • Once the chart is rendered using JavaScript, if new DataXML is set, the Chart was not rendering for the first time. Second time onwards it was rendering properly.
  • If a blank chart is rendered using JavaScript, it was not possible to update with a new Data XML. Chart threw exception if tried to do so.
  • While using JavaScript, if AnimationEnabled property was set to false, Chart was flickering while doing live update. Now this flickering issue has been fixed.

Current release also contains the following enhancements:

  • Label Placement for Funnel Chart has been optimized to overcome DataPoint label overlap.

New Features:

  • New property DataPointWidth has been introduced at the Chart level which allows the user to control DataPoint width in case of Column and Bar Chart types.

Visifire 2.2.3 beta Released

somnath

Hi,

We have just released Visifire 2.2.3 beta. In this release we have implemented Funnel Charts. You can see them here. You can create two kinds of Funnel Charts namely, StreamLineFunnel and SectionFunnel. You can go through Visifire Documentation to learn more about funnel charts.

Below is a summary of this release.

New Features:

  • Funnel Chart
  • In a single series Chart, each DataPoint takes different colors from ColorSet. Previously there was no option to override this behaviour. In this release UniqueColors property has been implemented in Chart to achieve it. If UniqueColors property in Chart is set to false, all DataPoints under the DataSeries take same color.

Enhancements:

  • Line chart with 5000 or more no of DataPoints took longer time to render. Now it has been optimized.

Bug fixes:

  • In line chart if MarkerEnabled property of a DataSeries/DataPoint is set to false, the corresponding legend entry was still displaying the marker while it shouldn’t.

Below is a screenshot of newly implemented Funnel Chart.

Visifire 2.2.1 released with one new feature

Sunil

Today we are releasing 2.2.1 with one new feature. As mentioned in the previous blog, Visifire 2.2.0 allows one to select a DataPoint using mouse or programmatically from Managed Code/JavaScript. But it is limited to one DataPoint per DataSeries. Now Visifire 2.2.1 gives you the ability to select multiple DataPoints.

In order to be able to select multiple DataPoints, you need to set the “SelectionMode” property to “Multiple” in DataSeries. By default SelectionMode will be set to “Single”.

Below is the XAML that I used.

<vc:Chart xmlns:vc="clr-namespace:Visifire.Charts;assembly=SLVisifire.Charts"
                    Width="500" Height="300" Theme="Theme1" BorderBrush="Gray"
                    Padding="8" View3D="True">

            <vc:Chart.Titles>
                <vc:Title Text="Product Sales - 2008"/>
            </vc:Chart.Titles>

            <vc:Chart.Series>
                <vc:DataSeries RenderAs="Pie" SelectionEnabled="True"
                               SelectionMode="Multiple" Bevel="False"
                               LabelText="#AxisXLabel, #YValue" LabelStyle="Inside"  >
                    <vc:DataSeries.DataPoints>
                        <vc:DataPoint AxisXLabel="USA" YValue="320"/>
                        <vc:DataPoint AxisXLabel="UK" YValue="260"/>
                        <vc:DataPoint AxisXLabel="Germany" YValue="180"/>
                        <vc:DataPoint AxisXLabel="France" YValue="120"/>
                        <vc:DataPoint AxisXLabel="Others" YValue="158"/>
                    </vc:DataSeries.DataPoints>
                </vc:DataSeries>
            </vc:Chart.Series>

</vc:Chart>

Apart from SelectionMode property, we have made one more enhancement. Now Selecting/Deselecting a DataPoint programmatically or by mouse causes the DataPoint to Explode/Implode in turn. But it doesn’t work the other way around. As a result of which, Exploded property works independently.

Below is the summary of this release:

New Features:

  1. SelectionMode property has been added at the DataSeries level – which allows you to make multiple selection.

Enhancements:

  1. Selecting/Deselecting a DataPoint in turn causes the DataPoint to Explode/Implode.

Bug Fixes:

  1. Chart used to throw exception whenever there is no DataPoint in the DataSeries.

Visifire 2.2.0 Released!

Chirag

Hi,

Visifire 2.2.0 is out of beta. Now Visifire supports DateTime values in AxisX. Exposing itself to wide variety of user data, with numerous bug fixes, Visifire 2.2.0 is emerging out of beta with triumph! Thanks users for pushing Visifire to the limits, with such a wide variety of data. We dedicate this release to you.

This release also comes with one more new feature. DataPoint in a series can be selected on click. A selected DataPoint can be deselected by clicking again on it. On selection the DataPoint stands out visually from the rest & the Selected Property sets to True. Only one DataPoint in a Series can be selected at a Time. In multiple series chart, one DataPoint in each DataSeries can be selected at a time. SelectionEnabled Property in DataSeries is the one which defines if a DataPoint is selectable in that Series. A Chart can be rendered with a DataPoint already selected, by setting Selected to True.

This release contains fix for the following bugs:

  • In few cases for Chart types Column & Bar, DataPoint clipped at the either ends.
  • If the first DataPoint was close to Axis’s Minimum value, then all DataPoints became small. Now it changes the starting point of Axis accordingly.
  • ColorSet couldn’t have been applied from XAML.
  • For Chart types Line & Area, gap to the left & right of the chart was more compared to other chart types.
  • For Chart types Column & Bar DataPoint Width was dependent on Interval, where as Width should be independent of Interval.
  • If Interval was given such that first DataPoint XValue was not a multiple of it, first DataPoint’s Value didn’t appear in Axis Labels at all.
  • Scrollbar appeared if there were more number of DataPoints with same XValue.
  • In few cases Scrollbar appeared for 2-3 datapoints and not for 5 DataPoints and above.
  • In few cases for DateTime values, DataPoints became wider than normal when ScrollBar appeared.
  • For DateTime values, DataPoints did not appear, if all of them had same XValue.
  • If AxisMinimum was set to a value higher than the lowest of XValues, then AxisY shifted to the right.
  • Chart with DateTime values accepted Interval even if IntervalType was not specified.

Current release also contains the following enhancements:

  • AxisMinimum and AxisMaximum can now be set for DateTime.
  • Now, TrendLine works with DateTime Values.
  • Previously, Tag property of visual elements was holding the reference of DataPoint/ DataSeries. Now onwards Tag will hold the information as ElementData, which in turn holds the details of Element (DataPoint / DataSeries) with which it is associated.
  • DataPoint can be accessed from a Visual element as shown below

    void
    Chart_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
    {
    ElementData eData = (e.OriginalSource as FrameworkElement).Tag as ElementData;
    DataPoint dataPoint = eData.Element as DataPoint;
    }

    Here’s how one of our user was able to use Tag property to make Chart interactive in Microsoft Surface Table with its native events.

Visifire 2.2.0 beta 8 Released

Chirag

Hi,

This release contains fix for the following bugs:

  • In WPF, style couldn’t have been applied from Dynamic Resource in XAML. (In Silverlight it is not possible yet)
  • Rendered event of Chart was firing only for the first time render of the Chart. Now, it fires on each render.

Current release also contains the following enhancements:

  • DataPoint and DataSeries references are attached to Tag property of its corresponding visual elements. So, DataPoint can be identified using Tag property under which it belongs.
  • In WPF, Theme can be changed at realtime. Any of the available 3 Themes or Custom Theme can be applied.
    For example: Chart.Theme =”MyTheme”, where MyTheme is the file name of the Theme file with out .xaml extension. Please find a sample project illustrating this here.
