Can't get chart colors to work right.

Version 4.3.4

The chart colors appear just fine in the legend, but not within the chart.

Also, notice that "count" field appears as an item in the legend -- why is the chart doing that? I've broken the counts up into ranges using rangemap so I expect that the count should be replaced by range. It looks like the color is being assigned due to the value of "count" be assigned GREEN. Here's the general syntax of my query:

"my events" | stats min(_time) as start by thing1 | eval duration=now()-start | rangemap field=duration "0m-20m"=1-1199 "20m-40m"=1200-2399 "40m-60m"=2400-3599 "60m+"=3600-15000 | stats count by range

      <searchName>My Saved Search</searchName>
      <title>Count of events in My Saved Search</title>
      <option name="charting.chart">column</option>
      <option name="charting.chart.nullValueMode">gaps</option>
      <option name="charting.chart.stackMode">default</option>
      <option name="charting.layout.splitSeries">false</option>
      <option name="charting.legend.placement">bottom</option> 

      <option name="charting.fieldColors">{"0m-20m":0x00FF00,"20m-40m":0x3399CC,"40m-60m":0xFFFF00,"60m+":0xFF0000}</option>

      <option name="charting.legend.labels">["0m-20m","20m-40m","40m-60m","60m+"]</option>

      <option name="charting.seriesColors">[0x00FF00,0x3399CC,0xFFFF00,0xFF0000]</option>

      <option name="charting.fieldColors">{0m-20m:0x00FF00,20m-40m:0x3399CC,40m-60m:0xFFFF00,60m+:0xFF0000}</option>

      <option name="charting.legend.masterLegend"></option>

      <option name="charting.secondaryAxis.maximumNumber">""</option>
      <option name="charting.secondaryAxis.minimumNumber">""</option>
      <option name="charting.secondaryAxis.scale">""</option>

Here's the deal: your search returns two fields: count and range. Splunk charts the count field, using the first color in the color series (green) for all values of count. You provided a legend, so it will always appear. However, count wasn't in the legend, so Splunk added it.

So that's why you got the result that you did.

If you want to color each bar separately, you will have to play some tricks. Take a look at this answer Change chart bar color based on data value for one way to approach it,

I added count to the XML to try to workaround this issue. Why is Splunk adding "count" in addition to my specified series? I've updated my question to show that count is removed but regardless, "count" appears in the legend. Could this be a bug?
