I have a dojox bar chart on my app, that is populated from a QueryTask everytime the extent changes.

enter image description here

I am making use of the Tufte theme (the only one that has a transparent background), and overriding the bar colours/outlines when i populate the chart:

chart1.setTheme(dojox.charting.themes.Tufte);
    chart1.addSeries("Languages", [
        { y: pctArabic, fill: "#C23A00", stroke: null, tooltip: ctArabic + " in Arabic },
        { y: pctMalay, fill: "#6BAE11", stroke: null, tooltip: ctMalay + " in Malay" },
        ....
    ]);
    chart1.render();

I have also been using the Esri sample as a reference, and have successfuly added a popup to my map which shows some totals per suburb in a dojox piechart:

enter image description here

My codes is identical to the sample, bar the fields have been swapped out.

template = new esri.dijit.PopupTemplate({
          title: "Tweet Languages in {SA2_NAME}",
          mediaInfos: [
            {
              type: "piechart",
              value: { 
                fields: [ 
                  "TotArabic", "TotMalay",
                 ....
                ],
                theme: "Tufte"
              }
            }
          ]
        });

My problem:

I need some control over styling the chart within the popup.

How do I force the pie segments to be specific colours, as per my bar chart example?

When I look at the API reference for Popup, mediainfos does not look like it has this level of control over the chart?

How do I override the tooltips with an alias like I did with my bar chart example?

I will also need to style the popup to have a similar dark grey background to my chart background, but I believe that won't be related to the chart, and should be achievable via styling the popup with CSS.

I would personally create the chart myself rather than trying to use the ESRI popup class and then add it to a simple info window.

Here is a link to a fiddle which gives the basic idea. I'd based upon ESRI's sample that you sited. I haven't shown how to populate your own data in to the series, it just uses mock data. Let me know if you are not sure how to do this:

    Many thanks for this. I updated your example to demonstrate how to read the values from the feature layer - see jsfiddle.net/slead/9gGrv/58

It looks like you are going to have to create your own theme. This blog post talks about how that is done: http://dojotoolkit.org/documentation/tutorials/1.6/charting/

  • Thanks for your reply. I tried this but its not coming on the map. I will share the code on JSFiddle and if you have similar code implemented in ArcGIS JSAPI then please share your code thanks a lot..
