Changing theme in ESRI tutorial

MichelleJean — Sat, 11 Dec 2021 08:57:12 GMT

Hi everybody,

Two questions regarding a ESRI tutorial.

1) The tutorial uses a Wetland theme for it's dojox charts.

var theme = "Wetland"; ‍‍‍‍

This is Wetland.js (from dojox website😞

define(["../SimpleTheme", "./common"], function(SimpleTheme, themes){
 themes.Wetland = new SimpleTheme({
 colors: [
 "#bfbc64",
 "#737130",
 "#73373b",
 "#7dafca",
 "#8d3c42"
 ]
 });
 return themes.Wetland;
});‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

I would like to replace Wetland.js with my own customTheme.js. But I cannot manage to reference the external file customTheme.js

Any support with a sample code (compatible with the tutorial code) would be very helpful.

2) The links in Wetland.js reference local stored files:

define(["../SimpleTheme", "./common"]‍‍‍

Do I need to replace these with http:// links in order to create a customTheme.js file?

Thank you,

Michelle

Michelle,

Attached is a working example.

It is just a matter of properly referencing the theme file in your code:

    <script type="text/javascript">
      var dojoConfig = {
        packages: [{
          name: "themes",
          location: location.pathname.replace(/\/[^/]+$/, '') + "/themes"
        }]
      };
    </script>‍‍‍‍‍‍‍‍

and setting a more complete path to the dojox libraries in your theme code:

define([
    "dojox/charting/SimpleTheme",
    "dojox/charting/themes/common"
], function(SimpleTheme, themes){

    themes.MyTheme = new SimpleTheme({
        colors: [
            "#FF0000",
            "#e0e860",
            "#0000FF",
            "#999999",
            "#636563"
        ]
    });
    return themes.MyTheme;
});
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Thank you for your time Robert Scheitlin, GISP‌

Your sample is very useful for coding future references.

Playing with the chart I found that if you swap the contents between tab1 - tab2, the chart will not render.

Is this a bug in the code?

var cp1 = new ContentPane({
title: "Pie Chart"
});

var cp2 = new ContentPane({
title: "Details",
...
});

cp1.set("content", chart.node);‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Michelle,

You need to resize the chart to get it to render in the first tab like this (line 63 to 65):

        function getWindowContent(graphic) {
          // Make a tab container.
          var tc = new TabContainer({
            style: "width:100%;height:100%;"
          }, domConstruct.create("div"));

          // Display attribute information.
          var cp1 = new ContentPane({
            title: "Details",
            content: "<a target='_blank' href='https://en.wikipedia.org/wiki/" +
              graphic.attributes.STATE_NAME + "'>Wikipedia Entry</a><br><br>Median Age: " +
              graphic.attributes.MED_AGE + "<br>Median Age (Male): " +
              graphic.attributes.MED_AGE_M + "<br>Median Age (Female): " +
              graphic.attributes.MED_AGE_F
          });
          // Display a dojo pie chart for the male/female percentage.
          var cp2 = new ContentPane({
            title: "Pie Chart"
          });

          tc.addChild(cp2);
          tc.addChild(cp1);

          // Create the chart that will display in the second tab.
          var c = domConstruct.create("div", {
            id: "demoChart"
          }, domConstruct.create("div"));
          var chart = new Chart2D(c);
          domClass.add(chart, "chart");

          // Apply a color theme to the chart.
          chart.setTheme(myTheme);
          chart.addPlot("default", {
            type: "Pie",
            radius: 70,
            htmlLabels: true
          });
          tc.watch("selectedChildWidget", function(name, oldVal, newVal){
            if ( newVal.title === "Pie Chart" ) {
              chart.resize(180,180);
            }
          });

          // Calculate percent male/female.
          var total = graphic.attributes.POP2000;
          var male = number.round(graphic.attributes.MALES / total * 100, 2);
          var female = number.round(graphic.attributes.FEMALES / total * 100, 2);
          chart.addSeries("PopulationSplit", [{
            y: male,
            tooltip: male,
            text: "Male"
          }, {
            y: female,
            tooltip: female,
            text: "Female"
          }]);
          //highlight the chart and display tooltips when you mouse over a slice.
          new Highlight(chart, "default");
          new Tooltip(chart, "default");
          new MoveSlice(chart, "default");

          cp2.set("content", chart.node);
          setTimeout(function(){
            chart.resize(180,180);
          }, 200);
          return tc.domNode;
        }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Hi Robert Scheitlin, GISP‌ ,

I used the script referencing the theme file

<script type="text/javascript">
  var dojoConfig = {
    packages: [{
      name: "themes",
      location: location.pathname.replace(/\/[^/]+$/, '') + "/themes"
    }]
  };
</script>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

but when introducing this code line

chart1.setTheme(MyTheme);‍‍‍

the chart stops working.

And I do not understand why

Thank you,

Michelle

Michelle,

You have a couple of issue in your code. You need to add the theme package to the existing dojo config package list and not add another dojoConfig. Next you never added the myTheme to your require list (lines 88 and 95):

Hi Robert Scheitlin, GISP

Thank you for your time, now I understand

But it still doesn't work when loading on a web server, it only loads on localhost:

Michelle,

The answer is right in your browsers web console:

Your path to the theme is incorrect.
