John:
It's been a while since I've standardized my axis' configs, rusty now on
charting anomalies.
First the data.
(1) Date/Time is captured in 1/100th second intervals, with values
presumably recorded in each of the three tables; sourced from a family
of sensors performing a whole lot of sampling. Do discrete data points
in each of the three tables align upon a common date/time value, e.g.
all three tables have a data point containing dateTime value 08/06/2023
03:09:03.03? (meaning they share a common Label value. If not, there's a
View trick to overcome the anarchy for charting purposes.)
(2) Do all three series share the same horizontal spatial configurations
of the series chosen for labels?
(3) How does R:Charts recognize the Scale Increment text value "Two
Hours"?
(4) My experience of axis configuration is similar to yours. The
frequency and spacing of Labels seems to depend on the frequency and
spacing of Tick Marks. I can't say I know everything about that. But
note the variance of minor/major Tick Mark spacing along the axis. The
spacing of the minor ticks in the first and sixth segments is reduced
relative to those within the second through fifth segment, suggesting a
"crowding" . Take a shot at standardizing the spacing:
-- Chart Editor > Chart > Axis > Bottom Axis >
-- Ticks Tab: Reduce the "Minor" Count to = 1 (or 0, as the Minor Ticks
aren't very useful here)
-- Labels Tab > Styles Sub-Tab: Play with the "Min. Separation %" value
(5) Thinking, too, that the width of each dateTime value may be a
factor. Granted, your Labels Tab > Style Sub-Tab > [x] Multi-line
staggers the Labels; but note the uniformity of the vertical margin
spacing between the top and bottom row. You may be "minned out" for
horizontal adjustment. Perhaps redefining your Label value solely as a
Time data type might provide lateral flexibility?
Hope there's something there for you.
Best, Bruce

DateTime X Axis
Bruce,
Thanks for your reply. I have attached two pdfs, one showing the
settings I am using and the other the resultant graph. Changing the
settings seems no have no effect on the labels so presumably I am doing
something wrong. The data is being plotted from three tables with
differing datetime values.
Any suggestions that you have would be much appreciated.
Thank you.
Regards
John Docherty

Subject [RBASE-L] - R:CHARTS - Adjusting the Label Increments on a
DateTime X Axis
Hi,
I am having difficulty setting the increments between labels /
gridlines on a X Axis which consists of datetime values. While I have
managed to get this to work properly in the past I have had no
success with the current data. If anyone can tell me how to set the
increment to say 2 hours that would be greatly appreciated. (Even if
I try to use the 'standard' intervals from the drop-down list that
does not change the labels or their spacing. Presumably I am doing
something wrong, but I am not sure what that is....)
Thanks.
Regards
John Docherty
