Data Visualization
1. Quiet Status on Dashboard should have non-alerting color
2. Single Number should be communicated with alerting color, Icon graphic ( tiny, "SparkCon ???")
3. Large data set are good for Line Chart Period Analysis. Small data set mush rely on Bar Chart.
4. Period comparison should not use line chart overlay. Comparison= Delta of %
5. How to Breakdown a variable:
Human are good in visualizing Height no area plot, unit plot, Pie chart ( need to calculate area, counting, pizza size w/o number). Sorted Bar chart are better.
6.Breakdown over a period of time:
Bar chart side by side comparison with different color will show difference and trend
Stack line or bar are not clear.
7. How to visuaize Category:
Map, Shapes, Color, Lines
8. How to visualize Quantity:
Size, Count, Speed, Color Intensity, Height Comparison.
9. Typical usage: Cluster Point Chart, Bar with Median, Mean, Sorting, Markup Chain Workflow Graph. Highlighting GridCell, Projectin, Targeting
10. Other techniques: Click-through, Grouping, Multi-factor, Summary and Rating, Confidence Level to filter out outliers

<!-- required to read the <dataCacheClient> element -->
<section name="dataCacheClient" type="Microsoft.ApplicationServer.Caching.DataCacheClientSection,

<!-- (optional) specify local cache
<localCache

<!--(optional) specify cache notifications poll interval

<hosts>
<host name="jqdappfabric" cachePort="22233"/>
<!--name="CacheServer2"

</hosts>
</dataCacheClient>
Note that there are 2 DLL from server that can be used on XP ( only suppoed to installed to Win7 but it works
Microsoft.ApplicationServer.Caching.Client.dll
Microsoft.ApplicationServer.Caching.Core.dll
The other two may be useful:
Microsoft.WindowsFabric.Common.dll
Microsoft.WindowsFabric.Data.Common.dll

WPF 300DPI High Resoluation Printing
PrintDialog dlg = new PrintDialog();
GeneralTransform transformToRoot = this.TransformToAncestor(win_root);
Rect rect = new Rect(transformToRoot.Transform(new Point(0, 0)), transformToRoot.Transform(new Point(this.ActualWidth, this.ActualHeight)));
double scale = 300 / 96;
RenderTargetBitmap bitmap = new RenderTargetBitmap((int)(scale * (rect.Width + 1)), (int)(scale * (rect.Height + 1)), scale * 96, scale * 96, PixelFormats.Default);
bitmap.Render(g); // g=grid
Image img = new Image();
img.Source = bitmap;
img.Stretch = Stretch.None;
img.Measure(new Size(dlg.PrintableAreaWidth,
dlg.PrintableAreaHeight));
Size sizeImage = img.DesiredSize;
img.Arrange(new Rect(new Point(0, 0), sizeImage));
dlg.PrintVisual(img, "Test300DPI");
For 3D:
Rect = Viewport3DVisual.ViewPort and it comes from visual brush:
<Border>
<Border.Background>
<VisualBrush Stretch="None">
<VisualBrush.Visual>
<Viewport3DVisual x:Name="visual3d" Viewport="0 0 384 384">
