  3. Silverlight extension - mapping datapoints to the named objects

    in General

    Posted

    Hi,

    I'm using the silverlight extension to chart some data.  In order to bolt on interactivity, I'm trying to figure out which named objects are associated with each datapoint. 

    Do you have any best practices for doing this?  Because of your architecture, I am effectively sending the data back from the server twice - once with your graph, then again to associate the data.  This is unfortunate, but liveable.  Now.. I have your graph, with some named objects.. and I have the data.  It's unfortunately, not a 1:1 mapping.  What can I do?

    I notice that the output from the silverlight writer includes a "canvasmap."  This has the information that I need.  Could you expose that from the silverlight chart control?  That would certainly make my life easier.

    My other option is to try and read the webform directly, and steal that data..  but that's not going to be much fun.

    Thoughts?  Does the flash writer have this same problem?  Is this the right forum for this question?

  4. Turn off highlighting

    in General

    Posted

    I have a bar chart that I've created from a datasource.  When I mouse over a series, after a bit of time, all values not in the series dim.  I assumed this could be turned off by

      Chart1.Highlight.Dimmed = false;   Chart1.Highlight.Enabled = false;

     But, it doesn't seem to have an effect.  How do you turn this off?

     

    Thanks,

  5. & in a label causes an error

    in General

    Posted

    Hi,

    I have the following pseudocode which is throwing an error:

      string sql = "some sql";

      DataTable dt = DataLayer.GetSqlDt(sql);

      Chart1.DataSourceSettings.Fields.Add(new FieldMap("PRODUCT_FAMILY", FieldUsage.Label));

      Chart1.DataSourceSettings.Fields.Add(new FieldMap(dt.Columns[0].ColumnName, FieldUsage.Value));

      Chart1.DataSourceSettings.Fields.Add(new FieldMap(dt.Columns[1].ColumnName, FieldUsage.Value));

      Chart1.DataSource = dt;

      // The current implementation of Silverlight Writer does not support artistic borders

      Chart1.Border = new SimpleBorder();

      // Note that the Renderer has been set to Silverlight using the code below but it can

      // be also set at design-time

      Chart1.OutputWriter = new SilverlightWriter();

    One of the "PRODUCT_FAMILY" rows has the following data =  <PRODUCT_FAMILY>LL & BACKHOES</PRODUCT_FAMILY>

    The resulting XAML is

    <TextBlock Text="LL & BACKHOES" Canvas.Left="278.7413" Canvas.Top="208.375" FontFamily="Arial" FontSize="10.66667" Foreground="#000000">

    Notice that the & is no longer encoded.  This throws an error.

     

     

  6. OLAP & Silverlight?

    We could create our own interactivity though, correct? 

     For example, in Silverlight, I should be able to "find" the uniquely named objects (ellipses, I believe).  Then I could add events to the mouseover to create a multiselect capability, right?

    Load the project.  See compilation error:chartfxPageError.jpg

    Copy the dlls you sent to the clientbin of silverlight project and bin of web project.  compilation error goes away.  Open page.xml in designer.  Get "loading" message - chartfxPageErrorLoading.JPG

     Wait a while.. then get this error - chartfxPageErrorLoadingExc.JPG

     Running the project just gives me a blank screen.

    Thank you for the sample, but it still doesn't work for me.

    Your chart control is referencing an assembly that is distributed with 1.1. Could you rebuild your controls on a machine that does not depend on 1.1?  Or do I just need to install the 1.1 sdk?

    Are you going to revamp your samples to work with Silverlight 2.0?  As of now, the projects won't even open with the latest and greatest.  After doing the trick to upgrade the projects, I can't get them to compile.. 

  14. Selecting data

    in General

    Posted

    Hi,

     We are about to start a new silverlight endeavour involving charting.  We need the ability to select data within the chart.  For example, selecting a few values within scatter plot. Do the chartfx charts have this capability? This was not available in the demo on the main site. 

     TIA,

     Darin
