display google line chart (image) with single value

Question

I am using the deprecated Google Line chart (image) in my website. Using this chart I am creating differnt reports. If it has only one value, it does not display the chart value. But I want to display that single value in Line Chart by default.

With the common Google Line chart I set the "'pointSize': 3" and I solved the problem, but with image api, I dont know if it is posible

this is my example of the chart with only one value:

Anyone knows how to do something like that?

Answer 1

If I understood well you should try adding something like this:

&chm=o,,0,,5.0
