Bar Chart in Pop up

FaizanTayyab — Mon, 12 Sep 2011 11:18:44 GMT

Hi

I have a popup config file as below, to show a bar chart within a popup.

<fields>
        <field name="BLOCK_NAME"/>
        <field name="CO__1"/>                    
        <field name="CO__2"/> 
        <field name="CO__3"/>                    
        <field name="CO__4"/> 
        <field name="CO__5"/>                    
        <field name="CO__6"/> 
        <field name="CO__7"/>                    
        <field name="CO__8"/>
        <field name="CO__9"/> 
        <field name="CO__10"/>                    
        <field name="CO__11"/> 
        <field name="CO__12"/> 
        <field name="CO__13"/>                    
        <field name="CO__14" /> 
        <field name="CO__15" /> 
        <!-- <field name="LINK" alias="Document" visible="false"/> -->
    </fields>
    <medias>
        <media type="piechart" title="Block Partners" chartfields="CO__1,CO__2,CO__3,CO__4,CO__5,CO__6,CO__7,CO__8,CO__9,CO__10,CO__11,CO__12,CO__13,CO__14,CO__15"/>
    </medias>

However it displays nothing. Anyone having similar issues.

One reason for this behavior could be that, the values within the chartfields are of strings data types and are of format:

string (%number)
for example company1(%50)

In SFV 1.3 i had to do some string processing in the chart widget to generate the chart however i am not sure how to do the same in SFV 2.4 without using the Chart widget and having the chart within the Popup.

Any ideas???

Could you use http debugging tool such as firebug/fiddler/http fox to see if what is the request made and what does the response contain?

I will try to use firebug and let you know the outcome,

However when i tried an integer type field, the chart works fine.

However as mentioned, the data inside the field i require is of type string and has the format

as
companyName(%20).

Is there anyway to allow the popup to use the numeric portion for the pie chart slice and the companyName as label. As the popup is builtin in the API, i wasnt sure how to make this work.

I had to include three files from the API itself to make this work. The main file is PopUpMediaBrowser which has the method to get Chart data. I placed the string processing code in this method and got the chart to work.

Again, the charts require the field data type to be esriIntegerType or a string which can be converted into a number.

Next target is increase the size of the media window, currently it cuts off the chart.
