How to show Time Series Chart data based on a List (multi) selection

[bhnaim]

Hi all,

I am trying to find a way to make the Time Series Chart widget able to show only the data that is selected on the list widget (multi-selection available).

How to do that ?

Thanks in advance.

This video helped me a lot! Thank you very much. 

But the multi-selection is not working ... I can only show one data at a time... 

Every time I select multiple rows, only the data of the last selected row is shown.

Any idea?

Without knowing  more details it is hard to say.

Could you pass the returned data to a grid, as a test, to see if it is the service not returning the correct data?

If it is returning the correct data then it will probably be a configuration issue (DataSource) on the time series chart.

If it isn't returning the correct data then I would pass the input params table into another grid to check that the input table has your multi selections. I'm assuming that you are binding the 'SelectedRows' from the GetLoggedProperties service to propertyNames parameter of the QueryNamedPropertyHistory service.

So, I made few tests with a grid as you asked me :

I created a new grid and bound the QueryNamedPropertyHistory 'All Data' into the 'Data' grid.

Every time i select a single row, the grid shows the correct data. But when i multi select a second row, only the second row data is shown.

(For info, i didn't use any custom service. They are all Thingworx provided ones).

The more i try, the more i feel i am missing something with multiselection.. is there any example of a multiselection List widget that provides a Grid widget with the current data selected ?

Because in my case, i have never been able to have more than the data corresponding to the last selected item in the list shown in the grid..

Hi @bhnaim.

Are you trying to combine different data sets into one single data set or display multiple data series into one time series chart?  We're going to need more information for determining an approach to handling this.
