Stacked bar chart with line graphs needs to be displayed which inturn should be linked to a filter component. Based on variables in filter component graphs and lines should be changed.
Environment
Dashboard 4.0 SP5
I will be connecting to universe through query browser which is built on Netezza database
you can create stacked bar chart and combine line chart by overlaying on it.
The y axis values should be same as for both stacked column chart and line chart.
you can offset legends to show them remove chart title for line chart and un-check horizontal axis labels and vertical axis labels from appearance >> text
To link line graph values to filter (if by filter you mean a combo box or list view) you can use insertion tab and map source and destination to feed selection from chart to a cell in excel and from behavior tab in combo box you can >> Selected Item > type as Dynamic and map Item to the cell where you are inserting chart values
