Hi Hank,
We are working on some “computed transforms” features that should make things like this alot simpler, but they are not ready yet. In the mean time the suggestion is to pre-format all the dates (in python) however you would like them to appear, and then add this as a new column, e.g. “formatted_date”, in your column data source.
sourcetds = ColumnDataSource(
data=dict(
year=years,
value=values,
formatted_date= # you format the dates as strings however you like here
)
)
Then your tooltip template should reference this column:
hover = HoverTool(
tooltips="""
<div style="background: #FFFFFF;">
<span style="font-size: 20px;">Year, TDS Value</span><br />
<span style="font-size: 16px; color: black;">(@formatted_date, @value)</span>
</div>
"""
instead of (@year, @value)
Thanks,
Bryan

Hi Tom,
I tried to follow the post you mentioned. However, I have no idea how to modify my code from the post?
Thanks,
Hank

The discussion at Date time format in Hovertool might help.

Hi all,
The tool tip does not show the date in the correct format in the line chart.( the image below). However the data was displayed in the correct format in the table below.
My code is listed here. Could anyone share some useful information to convert the integer to the year/month/day in the tooltip. Thanks,
Hank
def makeplotTDS(samplesTDS):
years=[ri["CollectionDate"] for ri in samplesTDS]
values=[ri["TdsValue"] for ri in samplesTDS]
