OBIEE Master and Detail relationship - master-detail

I am trying to create some reports using the master/detail functionality. I tried this using a table and bar graph, a table and line chart, and it's working fine.
Now I am trying to build master/detail functionality between a bar graph and line chart using a slider but it's not working. How can you set up the master/detail functionality without using a table.

Master-detail only works on text labels.
As of versiĆ³n 11.1.1.7.1, clicking on the bars,lines,bubbles/etc. does not trigger the master-detail event. You must click the axis lables on your graph; if the master atribute is used in the "Color by" section, you must include a legend and click on the legend labels.

Material Table - is it possible to move row selection text from toolbar to the bottom of page

I'm using Material Table at the moment and am having difficulty customizing the position of the selection text (presented when one or more rows are selected via the checkbox).
Looking at the documents, I can see that the toolbar is overridable (https://material-table.com/#/docs/features/component-overriding), however the examples show simpler changes e.g. how to change the background color. I wonder if it's possible to separate the selection text from the toolbar and render it in a different location, like the below picture demonstrates.
Does anyone know if this is possible?
In the end, I turned off the row selection text in the toolbar by using showTextRowsSelected: false
I then made a custom footer using the row data presented by the onSelectionChange handler.

Google Data Studio - Custom Metrics and Drill Down Options When Hovering Over Graph

I have a times series graph in Google with drill down options for the date fields as well as two custom fields. When I go into view or edit mode and hover over my graph to select custom metrics, they are not showing up.
My time series graph
Settings for my graph
Some of my other times series and graphs on the same page have optional metrics that show up when I hover over them. All the other graphs in my report don't have this problem.
Things I have tried.
Refreshing Data Source
Refreshing the page
Enabling and re enabling the custom metrics
I'm not sure what else to do as I am still somewhat new to using this tool. Any hints would be much appreciated!
A couple of reasons:
1) Text Box
One possibility is that the Text Box may be ordered ahead of the Time Series Chart, thus blocking the top of the chart (Right click on the Text Box and set the Order to Send to back), however, when the chart is selected, it should show, thus #2 should do the trick:
2) Chart Header
It may be currently set to Do not show; it can be changed by heading to the Style Tab of the respective chart, scrolling down till the Chart Header section and selecting Show on hover from the drop-down.

Dynamically creating/accessing the Chart while visualizing the dashboard in Google Data Studio

We are trying to display two pie Charts in the default Dashboard and when user clicks on one of these pie-charts the data-table of the selected pie-chart should overlay/override on other pie-chart dynamically.
For example:
The dashboard displays two pie-charts by default. The pie-chart on
the left side display the employee and salaries data. The right side
pie-chart will have the employee and locations data.
When user clicks on the left pie-chart, the right pie-chart should be
overlay/override by a bar-chart OR data-table which contains the
employees' hierarchy, organization hierarchy with salaries. And user
clicks outside the pie-charts the default view with two pie-charts
should display.
Similarly when the user clicks on the right side pie-chart, the left
side pie-chart should be overlay/override by different bar-chart OR
data-table which shows the employees and their working locations.
Please find the attached screenshots in reference to the above example.
Default Dashboard
After the user clicks on the left side pie chart in the default dashboard
We tried available filters but they works with in the graph/chart, but not overriding existing graph with another graph.
Please guide us on how to achieve the dashboard.
The current native charts and feature set does not enable changing chart types on the fly in view mode.
That being said, you can create your own customized chart in javascript that will let you do this.
Alternatively, if clicking does not require filtering of the data, you put a transparent box on top of each pie chart and hyperlink to separate pages with the correct charts.

Use a relationship to filter data in power BI

I am working with a clustered bar chart that is influenced by a relationship to another table. When data is selected in that table I get the following result:
The dark green being the data that matches the relationship and the light green being the whole data set.
However, because sometimes the bars are very small, I would like to have the bar chart adjust to only include the data from the current selected relationship, as shown below.
Is there a way to limit the chart to only the data relevant to the current relationship? Alternatively, is there a way to filter out all values that are zero from the current relationship?
The way to do this is to click on the chart, go to the format tab, click on "edit interactions", and then click on the little filter icon at the top.

ExtJS grid-like custom control

I need to implement grid like control that utilizes some complex custom widgets for viewing and displaying rows. Just like this one:
The key point here is that controls in the right column depend on the value selected in the combobox from the left column.
Does anyone know what is the best way to implement it using ExtJS 5.0 components? Should I create my own widgets to display row data that will serve as both custom renderers and editors?
I would use a beforeedit function which changes the editor of the right column (setEditor) to the required widget type depending on what is set in the left column. If you use Editing (RowEdit) plugin instead of CellEditing, you would also have to setEditor in the left column's change or select event.
This is the easiest way, but it won't show all editors at once, of course.
To have all editors displayed at once, I would make a new field containing multiple fields. You can add multiple instances of these fields to a fieldset, container, panel or form at runtime.
