QUESTION
I added Google line chart (from here) on HTML page on Google web app and the data table comes from Google Sheets. Initially, line chart was accepting 'number' for x-axis but I changed it to 'datetime' and it accept date in "new Date(yyyy, MM, dd, HH, mm,ss)
"
But i am able to change the format of the date but chart is not working.
My problem is similar to this question, but this is my first time working with Google web app or JavaScript. So, i was unable to understand the solution.
Below is the sample data table:
Date SP1 Sp2 02/09/2021 00:02:34 2 3.5 02/09/2021 01:02:34 4 7 02/09/2021 02:02:34 10 14Code.gs:

Answered 2021-Sep-23 at 01:52I believe your current issue as follows.
- In your script, the value of column "A" is like
'2021,02,08,21,32,34'
. In this case, this cannot be directly used as the date scale. - In your sample Spreadsheet, the data has 3 columns. But in your Javascript, 4 columns are used.
- About
data.addColumn('number', 'Days');
, from your sample Date values,02/09/2021 00:02:34
,02/09/2021 01:02:34
and02/09/2021 02:02:34
, in this case, I thought thattimeofday
might be suitable.
When above issue was resolved from your script, it becomes as follows.
Modified script:In this case, please modify your Javascript as follows.

Answered 2020-Feb-07 at 11:59Your problem is that your HTML Element chart_div
is not created until the popup is open. But you try to init the chart on the not created HTML Element.
Call drawChart()
after the popup is opened.
Update your layer_name function and add the openpopup
event to the layer. It will called when you open the popup.
