Chart Widget

TinaCanady — Fri, 14 Dec 2012 16:56:51 GMT

I am using OTB chart widget and would like to be able to summarize the different types of pipe material in the pie chart. For example ac, ci, di, pvc. This is what I have so far:
<configuration>
    <labels>
        <layerselectionlabel>Select layer</layerselectionlabel>
        <drawtoolmenulabel>Select draw tool</drawtoolmenulabel>
    </labels>
    <layers>
        <layer label="Water Pipe Material" url="http://wr_modeling/ArcGIS/rest/services/UtilitiesDashboard/MapServer/12">
            <labelfield>MATERIAL</labelfield>
            <fields>
                <field name="MATERIAL"/>
    <field name="SHAPE_LEN"/>
            </fields>
           <medias>
                       <media chartfields="SHAPE_LEN"
                       title="Length of Pipe Material"
                       type="piechart"/>
            </medias>
        </layer>

    </layers>
</configuration>

Did you ever make progress on this, I have a similar issue on the forum...

No I did not.

So, what are you getting that isn't what you want?

If I use the same config that you have, I get all the pipes, summarized by type, and shows percentage of that type as well as total length for that type pipe.

So, what specifically do you want when you say summarized by different types of pipe material?

Thank for showing interest. Say I select 50 water pipe segments. Of those 50 I have 25 segments of CI material and 25 segments of PVC material. I would like the chart to say 50% AC with a total of 225' and 50% CI with a total of 325'. Instead the chart depicts each pipe segment separately. I hope I am explaining this clearly enough. Thanks.

If I use this for my config:

<configuration label="Charts (example)">
    <highlightcolor>0x336699</highlightcolor>
    <layers>

        <layer label="Pipe Size" url="http://gis01.wch-rcc.com/ArcGIS/rest/services/rkz/chart/MapServer/0">
            <labelfield>MATERIAL</labelfield>
            <fields>
                <field name="MATERIAL"/>
                <field name="Shape_Length"/>
            </fields>
            <medias>
                <media chartfields="Shape_Length"
                       title="Pipe Type"
                       type="piechart"/>
            </medias>
        </layer>

    </layers>
</configuration>

I will get this if I select a group of pipes:

[ATTACH=CONFIG]22699[/ATTACH][ATTACH=CONFIG]22700[/ATTACH]

So, if I hover over the results, it reports it as percentage of pipes by material, and also adds the total length.

R_,
I have attached examples of what I end up. Individual line totals. I am using a dynamic map service...could this be the problem?

<configuration label="Charts (example)">
    <highlightcolor>0x336699</highlightcolor>
    <layers>

        <layer label="Pipe statistics" url="http://wr_modeling/ArcGIS/rest/services/UtilitiesDashboard/MapServer/12">
            <labelfield>MATERIAL</labelfield>
            <fields>
                <field name="MATERIAL"/>
                <field name="SHAPE_LEN"/>
            </fields>
            <medias>
                <media chartfields="SHAPE_LEN"
                       title="Pipe Type"
                       type="piechart"/>
            </medias>
        </layer>

    </layers>
</configuration>

I use pretty much entirely dynamic services in my main config, so it is not that, especially since it's loaded in as a type feature (the /12 at the end of URL) in the chartwidget.xml.

What is C900 (the value reported in your chart), is that a line "type"? What field is it coming from?

Also, take a look at your rest services and make sure you have the correct values for MATERIAL and SHAPE_LEN and make sure you have the case correctly. Don't know what server version you are running, but know there have been some changes. In 10.05 the shape length field is actually Shape_Length.

I am having a similar problem. I want to see a pie chart showing the percentage of selected line segments in each CCOL1_1 category (in the preceding example above, s/he wanted them classed by Material). My chart seems to show every single line segment as an individual 'slice of pie' rather than the total segments. This is my first time attempting the chart widget. Thanks for any help!
