Sorry Jim, I saw that you answered to the other Steven.
I had a question and nobody responded to that yet, I thought you responded
to me.
I searched for mine and your email came up, but I realize the subject line
is different. My question was:
"How to change x axes labels in plot_ly?"

Hi Jim,

Thanks for your email.
My question was: how to change the x axis labels without changing the chart.
Or is that not possible?
Using your example, I added another column:
sydf<-read.table(text="year1 month-day rate
 1993 05-01 0.608
 1994 06-01 0.622
 1996 07-01 0.623
 1998 08-01 0.647
 2000 09-01 0.646
 2002 10-01 0.625
 2004 11-01 0.628
 2006 12-01 0.685
 2008 01-01 0.679
 2010 02-01 0.595
 2012 03-01 0.567
 2014 04-01 0.599
 2016 05-01 0.642
 2018 06-01 0.685",
                 header=TRUE)

How can I show the column "month-day" as labels on the x axis, but still
have the plot showing the chart as rate based on year?
I tried this:
plot(sydf$year,sydf$rate,type="b",
     xlab="month-day",ylab="Rate")

but this only changes the title of the x axis to "month-day". I want the
values on the x axis to show 05-01  06-01, etc.
Is that possible?

Thanks,
Steven

Hi Steven,
A basic plot can be displayed like this:

sydf<-read.table(text="year rate
 1993 0.608
 1994 0.622
 1996 0.623
 1998 0.647
 2000 0.646
 2002 0.625
 2004 0.628
 2006 0.685
 2008 0.679
 2010 0.595
 2012 0.567
 2014 0.599
 2016 0.642
 2018 0.685",
header=TRUE)
plot(sydf$year,sydf$rate,type="b",
xlab="Year",ylab="Rate")

When you add more years and rates to the data frame, the axes will change to
include the years and rates outside the ones in your example. As some have
noted, this is a very basic question.
