title: Change x-axis labels for ggsurvplot
body: <pre><code>library(survival)
  library(survminer)
  </code></pre>
  <p>I am using the survminer package to plot unadjusted Kaplan Meier plots. I am calculating mortality comparing different exposures and I have a very specific problem:
  <strong>Is there a way to change the x axis labels of ggsurvplot?</strong> In my case I want to replace the timepoint 0 with 30, timepoint 20 with 50, timepoint 40 with 70 and timepoint 60 with 90.</p>
  <p>I create my ggsurvplot using the code below:</p>
  <pre><code>fit31to90_Mortality &lt;- survfit(msurv31to90DayMortality~Bacteria_Category, data = 
  
  Mortality_31to90_Days_Plot &lt;- 
  ggsurvplot(fit31to90_Mortality, xlim = c(0,60), 
  break.x.by = 20, xlab = &quot;Day&quot;, ylab = c(&quot;Survival probability&quot;), 
  risk.table = &quot;abs_pct&quot;, font.x = c(26, face = &quot;bold&quot;), 
  font.y = c(26, face = &quot;bold&quot;), font.tickslab = c(24), 
  font.legend = c(24), risk.table.fontsize = 7, risk.table.col = &quot;black&quot;, size = 1) 
  Mortality_31to90_Days_Plot$plot
