How can I make only date appear in the X-label of xyseries plot?

[smhsplunk]

I only have year-month-day in my _time, when I use table to show in search, it only gives me dates. Yet when I use xyseries, it gives me date with HH:MM:SS. How can I make only date appear in the X-label of xyseries plot?

| xyseries _time,series,yval

Try this

... | eval time=strftime(_time, "%Y-%m-%d") | xyseries time series yval

I already have that, it still giving me long digits after the date. here is the code

<row>
<panel>
      <chart>
        <search>
          <query>index=xyz sourcetype=xyz1 source=xyz3 id!="nan" 
                        | search * id = "$new_hosts$"
                        | eval mytime=strptime(initial_date, "%Y-%m-%d") 
                        | eval _time=mytime
                        | xyseries _time,id,error_values</query>
        </search>
        <option name="charting.axisLabelsX.majorLabelStyle.rotation">-90</option>
        <option name="charting.chart">line</option>
        <option name="charting.seriesColors">[0x639BF1, 0xFF5A09]</option>
        <option name="height">200</option>
      </chart>
    </panel>
  </row>
