Hello Bubblers! i need help urgently on an app i am working on. i want to plot temperatures in a line graph using bubble chart. my data is like this

i want to be able to search for temperature records using Hospital Number as constrain. then group the search result by date of modification and plot each individual temerature record on a line graph. This is what i have done so far

But my graph is showing the count of the temperature rather than the actual temperature recorded

Hi there @abdullahi.alfa,

I think you’ll want to look into your value expression property.

Thanks for the response. But could you clarify what you mean by value expression property?

Oh I get it. But that value is only giving me one option which is what I am aggregating by. Under the aggregation there is no option that allow me to display individual temperature readings. Rather the options are count, sum, average…
