In a deephaven.plot.figure.Figure instance, the axis of a chart is defined separately from the series that will be related to it. The axis can be given a format pattern to use for values on that axis, and while that pattern is applied for xy series instances, it is not applied for category data.
Steps to reproduce
Open a python console in the web UI
Run the following script, to create a figure with an axis that has a pattern, and draw a category series on it
from deephaven.plot.figure import Figure
from deephaven import time_table
t = time_table("PT1s").update(["A=i % 3", "B = `b` + (i % 5)"])
p = Figure().x_axis(format_pattern="yyyy-MM").plot_cat(t=t, category="Timestamp", y="A", series_name="Series").show()
Observe how the x axis labels are rendered
Expected results
X labels should show in the yyyy-MM format.
Actual results
X labels show in the default yyyy-MM-dd HH:mm:ss.SSSSSS format:

Here's an analogous chart using an XY series:
from deephaven.plot.figure import Figure
from deephaven import time_table
t = time_table("PT1s").update(["A=i % 3", "B = `b` + (i % 5)"])
p = Figure().x_axis(format_pattern="yyyy-MM").plot_xy(t=t, x="Timestamp", y="A", series_name="Series").show()
Observe that the X labels follow the expected pattern.
