Adding additional information on plot tooltip

Hi

I have a plot , when i hover over the plot line, it displays the value. At the same time i would like to also display the temperture, which is also part of the dataset but not displayed on the plot.

How do i edit the tooltip, so that additional information can be displayed on the tooltip ?

Use function dataTipTextRow

Thanks

This my code now

plot(t,ug,ref_data_timestamp,ref_data_sensordata)

title('N02 Sensor Per Minute data')

xlabel('Date Time')

ylabel('N02 ug')

dataTipTextRow("Temperture",iot_temperture);

legend("Sensor ug", "Reference data")

When i click on the data trend on plot it does not still show the extra information

You need to attach it to the DataTipTemplate property. Check DataTipTemplate as well.

Hi

Ok i can get it working if my plot has only one data set e.g.

s=plot(t,ug)

But i gett the following error message, when a plot has multiple plots

s=plot(t,ug,ref_data_timestamp,ref_data_sensordata)

Intermediate dot '.' indexing produced a comma-separated list with 2 values, but it must produce a single value when followed by subsequent indexing

operations.

Error in n02 (line 141)

s.DataTipTemplate.DataTipRows(end+1) = row;
