I have a project that let's the user change which attribute field is used in the display.  It's based on the sample https://developers.arcgis.com/javascript/jssamples/renderer_dynamic_layer_change_attribute.html  For the legend, I'm creating it if it doesn't exist, but if it does, then I just want it to refresh.  My problem is that the title is based on a variable, defined based on the change event of the FilteringSelect list of fields.  When I change the field, the legend itself updates, but it still has the title from its initial creation. Can I change just the title?  It doesn't seem to be honoring my title definition when I specify legend.refresh().  In this example, fields is the array of attributes from my layer and fieldChoice is the selected item from the FilteringSelect.    domConstruct.empty("legendDiv");         if (!legend){                legend = new Legend({             map: map,             layerInfos: [{ "layer": featureLayer, "title": fields[fieldChoice] }]           },"legendDiv");           legend.startup();           }else{             legend.refresh();                       } ...

I am working on a menu that lets the use select a classification method, either quantile or equal interval, as well as letting them change the color or the number of intervals.  The number of classes is in a dijit/form/NumberSpinner.  The colors I have  in a FilteringSelect.  For both of those, I was able to have an event listener such as   registry.byId('classSelect').on ('change', function (){     numClass = registry.byId("classSelect").value;     drawFeatureLayer();   }); This lets the user change the interval and it immediately executes the functions that do the drawing.  I like the look of a radio buttons and I want to use those for my classification methods.  First I tried a dijit/formRadioButton.  This looks OK, but selecting between the two choices doesn't have very good styling.  The first button still has a little fill color to it, and the 2nd one does too, so it looks like both of them are selected. <h4>Classification method: </h4>      <form id="classForm"  action="">         <input type="class-method" name="method" id="btnQuantile" value="quantile" data-dojo-type="dijit/form/RadioButton" checked="checked"/> <label for="btnQuantile">Quantile</label> <br />         <input type="class-method" name="method" id="btnEqInterval" value="equal_interval" data-dojo-type="dijit/form/RadioButton" /> <label for="btnEqInterval">Equal Interval </label> <br />               </form> The other thing I'm not sure about is how I might have an event listener to the change in buttons.  All I can figure out is to add a 'Go' button which will read the classification and then execute my drawing function. registry.byId('btnClassify').on('click', function (){    var clsForm = dom.byId("classForm");         for(var i = 0; i < clsForm.method.length; i++) {           if(clsForm.method.checked){           currentMethod = clsForm.method.value;           }      } drawFeatureLayer();   }); Since I figured out I don't need a 'Go' button for either the number of classes or my colors, I'd really like to get rid of it all together and not have to have it just for my classification method. I suppose I could use another type of menu, but  I only have two methods. It looks klunky to have a dropdown menu that has just one other option in it.  Am I missing something obvious on how to detect when one of those two buttons are selected? ... View more

I found some code on github that lets you specify the number of classifications, color and type to create thematic maps.  It included a set of color ramps already written up from colorbrewer, so I didn't have to dig it out. There is no GUI on this set of functions that calculate the classifications. One thing I'd like to do, since I have all these great colors already, is create graphics from the color ramps and let that be what the user clicks on.  Unfortunately I don't see that I can add that kind of click event on a shape.  There are click events, but I don't see how I can pass the color name as an argument, anyway. The next thing would be to add a checkbox next to the ramps.  This is where I'm getting stuck.  Since I'm dealing with gfx, I'm not sure where to add checkboxes next to each graphic.  Mostly it's Friday afternoon and I'm getting tired. I created a fiddle for this.  For some reason it is only flashing the colors instead of leaving the color graphics on the screen.  If someone is available to help me out on this, I think it would be a nice way of offering color choices, rather than presenting either a list of color names, or the generic color palette. http://jsfiddle.net/8bx4vdv2/ I think I'm getting stuck on the fiddle because I'm attempting to only paste part of the colors I have available and I made a syntax error somewhere. ...
