Hide chart in Pentaho Report Designer if not data - pentaho

We are setting a chart on Pentaho Report Designer 5.3 and we want it to hide if no data is returned by the query, aligned to that chart.
We have used, the:
=NOT(ISEMPTYDATA())
in the visible style expression but it shows
chart_user_no_data_available
on the chart, and it is not working.
How do I solve this?

You can define a function that returns true/false. True means "have data", False means "No Data". Then, write in the visible style expression the following code :
=YourFunction

Is there a way to display a different graph only when you select a graph variable?

first, i wanna show only pie graph.
and only if i select one of the pie graph fragments, I'd like to show the corresponding bar graph value.
Is there a way?
In QlikView
Open the chart preferences
Add the calculation condition = GetSelectedCount(FieldName) = 1 (More about GetSelectedCount function)
Open Error Messages
Select Calculation condition unfulfilled
Enter the message. It can be a plain text or expression/calculation
Now if nothing is selected in Director field (or more than one value is selected) the error message will be shown
If only one value is selected then the chart will be calculated
In Qlik Sense
In the chart properties expand Data handling and add the condition in Calculation condition and the message in Displayed message (as in QV the message can be plain text or calculation)
Nothing is selected (or more than one is selected) and the message is shown
Only one value is selected and the chart is calculated

Edit Pop-ups on QlikView Chart

I have an expression Sum of Cycle Times in a bar chart. I want to display the equation used to calculate the value of the expression when I hover over the bar in the chart. Right now, the pop-up box displays the dimension value and the expression value. Can I edit what is displayed in the pop-up?
You can create a new expression with your expression formula in quotes and set it to 'Text as Pop-up'. This is a common practice in Qlikview charts as a means to get custom pop-up text. It's still not a perfect solution, but it will take care of your problem.

Report ,subreport pentaho

Iam using Pentaho report designer and we want to hide a subreport if there is no data .
I have tried to use this formula :
not(isemptydata())
in the visible expression but it does not seem to work .
So how to hide a subreport if no data .
Pentaho Report Designer elements have "attributes" and "style" sections. In style section there is a field "Visible". If you don't want to make the sub-report visible, it must be set to "false".
When want a function to disable it, the expression must return a "FALSE()" value.
You don't specify how the sub-report is generated and where is it placed (Details, Report Footer, etc), but, I'm gonna assume you have defined a function that has the count of rows for a group "TOTAL_ROWS" (and this is gonna be the field you are gonna compare), so, to hide the sub-report when 0 rows are present:
=IF([TOTAL_ROWS] = 0; FALSE(); TRUE())
"if the total number of rows is zero, return false, else return true".

Show / Hide Fields in Pentaho Report Based on User Input

I'm trying to show / hide fields in a Pentaho report based upon user input.
For example, I would like to offer a checkbox to the user saying "Show Product Count" -- if the box is unchecked, it will not include that column in the report.
Is there a way to do this in Pentaho Report Designer, perhaps using Parameters?
Thanks for the help -Monica
Yes, you have half the answer. Have a Yes/No Parameter "ShowProductCount"
Then on the conditional fields, go to the visible property, click the + formula icon and enter:
=IF([ShowProductCount]="Yes"; TRUE(); FALSE())
Simple! :)
There is more to this that the above answer. For example, if you don't want a field to show on the report, you pass the value mentioned above by Codek but the field will not show but the space for it will. The field has to be in a BAND and the band layout has to be set to ROW. Also, on the field you want to not display or display based on user selection, you have to set that field's style properties under size & position - invisible-consumes-space = false.
