I have a dashboard with a single value sparkline based off a timechart:

index=[theindex] event_name=[theevent]
| timechart span=1h count

I would like to increase the size of a sparkline so that it's more visible. How do I do this? I have been experimenting with making XML changes to dashboards and have some experience with CSS if that's necessary.

Hi

Give a try

<dashboard>
  <label>sparkline</label>
  <row>
    <html>
      <style>
        #rk .sparkline{
        opacity: 1 !important;
        stroke-width: 3px !important;
        }

        #rk .sparkline-delta{
        opacity:1 !important;
        stroke-width: 4.5px !important;
        }
      </style>
    </html>
  </row>
  <row>
    <panel>
      <single id="rk">
        <search>
          <query>index="_internal" 
| timechart span=1h count</query>
          <earliest>-24h@h</earliest>
          <latest>now</latest>
        </search>
        <option name="drilldown">none</option>
      </single>

    </panel>
  </row>
</dashboard>

Thanks Vnravikumar,

This was helpful and it increased the thickness of the line which made it easier to see from a distance, so it's a good solution, but I was hoping I could increase the vertical height, so that it takes up more space from the bottom to the top, so that changes in the line are easier to note. Is that possible? I attempted to add height and width as properties in the CSS, using both px and % as variables for them, but no change was observed. Are they not valid? Or am I using the wrong property?
