invoke tooltip programmatically form selection inconsist

[sylviat84]

I have 2 screens:

1- has (a) piechart and (b) tablechart, both generated with same underlying data

2- has (a) column chart and (b) tablechart, also both generated with same underlying data

On both 1- and 2- there are selection listeners on all charts such that  (a) listens for a selection on (b) and vice versa.  When an item is selected in (a), (b) updates it's selection to match (a), and vice versa.  

Tooltip option is "tooltip : {trigger: 'selection'} " on both the piechart (1-(a)) as well as  the table chart (2-(a)).

When the user clicks directly on 1-(a) or 2-(a) the tooltip works fine.  

But, when the user invokes a select event programmatically, the tooltip works on the piechart but does not work not on the column chart.

Gory details:  

on screen 1-, when the user clicks an item in (b), the piechart (a) is visibly selected & the tooltip DOES appear.

on screen 2-, when the user clicks an item in (b),  the column chart (a) is also visibly selected but --PROBLEM: the tooltip does NOT appear--.

Any explanation/fix for this?

thanks very much

Hi,

I attempted to reproduce this issue for a column chart, but was unable to. Here's an example of a ColumnChart using programmatic setSelection to select a random datum every 2 seconds: http://jsfiddle.net/ad34m3or/

If this doesn't help you with your issue, please post a link to either your website or a jsfiddle that reproduces the issue that you're experiencing.

Thank you so much.  From your example I was able to figure out my error.

 

I was setting 'column: null’  in 

chart.setSelection([{row: row, column: null]);

for both piechart and column chart.

It works in piechart.  I changed ‘column:1’ for column chart, as per your example, and it too works perfectly.  

Thanks so much for the great, prompt response.

You're welcome!

For further clarification, the primary difference lies in the fact that a ColumnChart may have multiple series (which are represented as columns), where for a pie chart, each row is a series, and it may not have another column that represents data. Therefore, for a PieChart, the selection model is row-based (specify a row with a null column), but for a ColumnChart, the selection model is cell-based (specify a valid row and column).
