Solved: [Chart] Bar Chart Configuring Questions (Fonts and...

jasuchung · ‎08-16-2023

I have defined stacked bar chart in my Splunk Enterprise Dashboard. I've been trying to solve this problem but I cannot solve them.. 😕 Please help me out.

These are the problems that I encountered:

1. As you can see in the line below `| eval PERCENTAGE = round(PERCENTAGE, 1)` I've rounded the data.
However, with data such as 7 and 10, ".0" gets dropped off for some reason. Our client strongly wants the data to be labelled in a uniform format. Is there a way to force natural number to appear as a integer form?

* 7 &10 (AS-IS) -> 7.0 & 10.0 (TO-BE)

2. Since the color of the Bar is Dark, I wanted to change the label in the bar to be White. I've wrote this line of code : `<option name="charting.fontColor">#ffffff</option>` However, this makes the whole font color including the ones in the axes.

3. I also want to change the label in the bar to be "Bold" and "Times New Roman" font-family. Is there a way to specify them?

This is my current code:

```XML

<row>
<panel>
<chart>
<search>
<query>
index = ~ (TRIMMED OF DUE TO PRIVACY ISSUE)
| eval PERCENTAGE = round(PERCENTAGE, 1)
| fields DOMAIN MONTHS PERCENTAGE
| chart values(PERCENTAGE) over MONTHS by DOMAIN
</query>
<earliest>earliest</earliest>
<latest>latest</latest>
</search>
<option name="charting.axisLabelsX.majorLabelStyle.rotation">0</option>
<option name="charting.axisTitleX.visibility">collapsed</option>
<option name="charting.axisY.abbreviation">none</option>
<option name="charting.axisY.scale">linear</option>
<option name="charting.chart">column</option>
<option name="charting.chart.showDataLabels">all</option>
<option name="charting.chart.stackMode">stacked</option>
<option name="charting.drilldown">none</option>
<option name="charting.legend.placement">right</option>
<option name="height">200</option>
<option name="refresh.display">progressbar</option>
<row>

```

Thank you

I don't think anything can be done about 1 as there isn't an option on column charts to specify the precision.

For 2 and 3, you can use CSS - give you chart panel an id e.g. boldtimes

  <row>
    <panel depends="$alwaysHide$">
      <html>
        <style>
          #boldtimes .highcharts-data-label text {
            font-weight: bold !important;
            font-family: "Times New Roman";
            fill: white !important;
          }
        </style>
      </html>
    </panel>
    <panel id="boldtimes">

Hi @jasuchung ,

A workaround for issue 1 could be adding a javascript extension to your simpleXML dashboard (see docs at https://dev.splunk.com/enterprise/docs/developapps/visualizedata/usewebframework/modifydashboards/). Script below, based on @ITWhisperer example, will add one decimal to all data values displayed in chart without it (e.g. 10 -> 10.0)

require([
  'jquery',
  'splunkjs/mvc',
  'splunkjs/mvc/simplexml/ready!'
], function ($, mvc) {

    pollAvailability = () => {
        if (mvc.Components.hasInstance("boldtimes")) {
            // Chart loaded
            let content = $("#boldtimes g.highcharts-label.highcharts-data-label.highcharts-data-label-color-undefined tspan:not(:contains(.)):first-child");
            // Add the decimal to data values without it
            for (let i = 0; i < content.length; ++i) {
                let text = content[i].firstChild.textContent;
                text += ".0";
                content[i].firstChild.textContent = text;
            };

        } else {
            // Chart not loaded yet, retry in 200ms
            setTimeout(pollAvailability, 200);
        }
    };
    
    setTimeout(pollAvailability, 600);
});

          }
        </style>
      </html>
    </panel>
    <panel id="boldtimes">

Thank u 🙂 Wish there was a way to make it in to a text just for labeling data 😿
