How to modify the color coding of a forecast graph

mohfarha · ‎04-04-2025

I'm using forecast graph for my data and it shows the graph in below format:

1. Existing data shows in solid Blue line
2. Forecast data shows in dotted Blue line
3. Confidence level (upper limit and lower limit with blue)

I want to change the forecast data color (refer attached).

There are a couple of ways you could do this as demonstrated below

<dashboard version="1.1" theme="light">
  <label>forecast</label>
  <row>
    <panel depends="$alwaysHidden$">
      <html>
        <style>
          #forecast g.highcharts-series-1.highcharts-line-series path.highcharts-graph {
            stroke: red;
          }
          #data g.highcharts-series-0.highcharts-line-series path.highcharts-graph {
            stroke: red;
            stroke-width: 3;
            data-z-index: 3;
          }
        </style>
      </html>
    </panel>
    <panel id="forecast">
      <viz type="Splunk_ML_Toolkit.ForecastViz">
        <search>
          <query>| inputlookup internet_traffic.csv | timechart span=120min avg("bits_transferred") as bits_transferred | eval bits_transferred=round(bits_transferred) | predict "bits_transferred" as prediction algorithm=LLP5 holdback=112 future_timespan=224 upper95=upper95 lower95=lower95 | `forecastviz(224, 112, "bits_transferred", 95)`</query>
          <sampleRatio>1</sampleRatio>
        </search>
        <option name="drilldown">none</option>
        <option name="trellis.enabled">0</option>
        <option name="trellis.scales.shared">1</option>
        <option name="trellis.size">medium</option>
      </viz>
    </panel>
  </row>
  <row>
    <panel id="data">
      <viz type="Splunk_ML_Toolkit.ForecastViz">
        <search>
          <query>| inputlookup internet_traffic.csv | timechart span=120min avg("bits_transferred") as bits_transferred | eval bits_transferred=round(bits_transferred) | predict "bits_transferred" as prediction algorithm=LLP5 holdback=112 future_timespan=224 upper95=upper95 lower95=lower95 | `forecastviz(224, 112, "bits_transferred", 95)`</query>
          <sampleRatio>1</sampleRatio>
        </search>
        <option name="drilldown">none</option>
        <option name="trellis.enabled">0</option>
        <option name="trellis.scales.shared">1</option>
        <option name="trellis.size">medium</option>
      </viz>
    </panel>
  </row>
</dashboard>

Hi @ITWhisperer ,

Thank you for sharing the details. I configured the same in my source xml and I can modify the colors accordingly.

Can you also help me to change the legend color 'forecast' as it is not showing in green.
