I have built a bokeh app that allows users to select windows in data and run python code to find and label (with markers) extreme values within these limits. For ease of interaction, I use the box select tool for the range selection. My problem arises when repeating this process for subsequent cases. After markers are placed for the results, they are rendered invisible by setting alpha to zero and another case needs to be chosen. When the new select box includes previous markers, they become visible based on the selection. How do I override this default behavior? Can markers be made unselectable? or can I add code to the customJS to hide them after they are selected?
Thanks in advance for any help!
There are a few possible approaches. If you just want non-selected glyphs to "disappear" visually, you can set a policy to do that as described here:
http://docs.bokeh.org/en/latest/docs/user_guide/styling.html#selected-and-unselected-glyphs
Basically, for bokeh.plotting, pass
nonselection_fill_alpha=0.0,
nonselection_line_alpha=0.0,
as arguments to your plot.circle call or whatever. Or if you are using the low level bokeh.models interface, something like:
renderer.nonselection_glyph = Circle(fill_alpha=0.0, line_alpha=0.0)
But be aware (I think you already are) that the invisible markers are still there, and still selectable if the user happens to draw a box over them with the selection tool.
If you truly want only a subset of the data to be visible and selectable after a selection, I'd say you want to replace the data in the column data source wholesale with the subset in your selection callback.

How can I display one dataseries as bar and another as a line in one graph like it is used in the last comment of: see last picture
Short answer:
It's not possible (yet) using the Grafana UI, only by hand.
Long answer:
As far as I know there is no way of doing this using the UI switches; you'll have to use the use the "alias or regex" fields below the visualisation configuration.
Prepare your data
Before you start, make sure that your queries A and B retrieve actual data. You won't see your data otherwise and be confused why they're not showing.
Adding fields and values to the aliases
Once you are selecting the correct data you want to display, just add the following on the visualisation section of the graph at the 'alias or regex' fields:
Add 2 overrides, one for each value you want to display using the 'Add series override' button.
Add a "Bars:false" option flag and a "Lines:true" for the value you want as a line.
Be sure to use the exact opposite values for your bars ("Bars:true" & "Lines:false")
Add a 'Y-axis: 2' to the value you want to have on the right side of your graph.
Optionally, you can add a "Z-index: 3" for the value that you want to have on top (I added this option to the line to make sure it's always drawing on top of the bars).
Enjoy
You should now have a nice graph with 2 types of data and visualisations in one; something like this:
For those who were asking in the comment section, yes this isn't available in version 8, however, you can still change the time series visualization to graph(old) so you can set the alias/regex.
I am trying to create something similar to this in PyQt5:

I tried using a separate QTextEdit widget for each bullet point and overriding the enter key to go to the next textbox, but I don't know how to make multiple QTextEdit widgets selectable (and able to copy paste) like in the example.
How can I allow the user to drag to select text across multiple QTextEdit boxes? Or is there a better approach to this?
I don't know this application is made from Qt or not,but I have an idea.
Parhaps you might have made the most part of this application... I can't know them from your question.I write my opinion on the premise that you don't know QText handling at all.
QTextEdit,QTextDocument,QTextCursor are used fully.
1.To understand block.
2.To use QTextBlockUserData(If you want.)
3.To use QGraphicsItem as nodes.
4.To go other page,we add a new QTextEdit on QStackedWidget or replace the QTextDocument of QTextEdit.
5.To make sub-nodes block,you can coordinate the indentation of blocks.
QTextBlock is a read-only data in a document.
You make QTextBlockUserData and set it to the block.
If you select multiple blocks you want to drag & drop , you use QTextCursor and movePosition methods with sequence.
The nodes of this application can not be QTextListFormat,because we cannot handle mouse click on the style.But you can insert empty-style QTextListFormat.
The truth of the nodes may be QGraphicsItem.
You can allocate it each the start position of blocks and the item can also have the block data.
It will difficult to take care of the connection between the nodes and the blocks.
In advance, you must set QGraphicsView & QGraphicsScene.
I insert many data on the container.
Which should we control with nodes or block?
My trial.
1.Nodes & Text
2.To the other page
3.Sub nodes & blocks
4.close sub nodes & blocks
My trial is incomplete,but it will be completed with endurance.
Logically,I think I can go step until the good point with these combinations.
But it will be diffcult...
These nodes are made from QGraphicsItem and allocated each Blocks.
You must calculate the position and recalculate during editing.
The mouse cursor image is deleted on these images.
It is outrange of screenshot.
In my (programmatic) Matlab GUI, I have a listbox uicontrol.
What I want is to display checkboxes in front of each option. When a user clicks the checkbox, it's marked (and the element will be considered during the calculations later). While if the user clicks the label, a description of the selected option will be displayed in a text uicontrol to inform the user what the option means.
Basically, I want functionality similar to installation programs where you can select components to install and can get information about said components by clicking them (which does not necessarily mark them as selected).
Is there a way to do this with checkboxes or something similar?
There are actually 2 built-in controls that you could use within Matlab:
com.jidesoft.swing.CheckboxList
com.mathworks.mwswing.checkboxlist.CheckBoxList
Usage example (more details in my Matlab-Java book):
jList = java.util.ArrayList; % any java.util.List will be ok
jList.add(0,'First');
jList.add(1,'Second');
jList.add(2,'Third');
jList.add(3,'and last');
jCBList = com.mathworks.mwswing.checkboxlist.CheckBoxList(jList);
jScrollPane = com.mathworks.mwswing.MJScrollPane(jCBList);
[jhCBList,hContainer] = javacomponent(jScrollPane,[10,10,80,65],gcf);
set(jCBList, 'ValueChangedCallback', #myMatlabCallbackFcn);
jCBModel = jCBList.getCheckModel;
jCBModel.checkAll;
jCBModel.uncheckIndex(1);
jCBModel.uncheckIndex(3);
There's no "ready" way for doing that - as listboxes take only plain strings as entries.
You could "manually" draw checkbox fitted into the area of the listbox, but that might mean quite a lot of work to get everything working...
Another alternative is to go for a java-componenent - e.g. using the jide components available in matlab. See e.g.
http://undocumentedmatlab.com/blog/using-jide-combo-boxes/
for a few examples.
I'm using gxt 3.0.1 and I have Basic Grid added on my form.
Now I've added filter for each column which can be used over TextBox in menu of grid columns (basically it's Filter Grid now).
I have to make my own TextBox above grid and apply filter to it. And do that for each column of grid.
Filtering is done locally.
My idea was to look for code they made for their TextBox and apply it on mine TextBox.
But I failed.
It should be just String filter, which should work exactly as filter provided in Filter Grid.
Also I'm using UiBinder.
From the GridFilters javadoc
* Filtering is adjusted by the user using the grid's column header menu (this
* menu can be disabled through configuration). Through this menu users can
* configure, enable, and disable filters for each column.
This is meant to be used to configure column header menus to have filters built in, not set up text boxes outside of the grid - see http://www.sencha.com/examples/#ExamplePlace:filtergrid for how this is intended to work.
To build the way you are describing, start instead with making a StoreFilter object based on the contents of the TextBox, adding it to the store, and re-applying the filter each time the contents of the text box change.
Check out StoreFilterField for a working example, or follow the above instructions to build your own.
If this doesn't work, please provide a code sample in your question...
I am working on a new project and I am using Joomla version 1.5.22.
I need to display one horizontal search form in the middle of home page and the same search form in vertical style in all other pages but in left position.
So what I did is, I created two template files one for horizontal search(horizontal.php) and other for vertical search (vertical.php) and in mod_modulename.php I tried to load the respective modules based on a certain condition and changed the position left or middle according to it. The positions are changed in the database to get effected in the admin panel.
if(condition) {
modModulenameHelper::changeToVertical($position);//to change position in database to left
require( JModuleHelper::getLayoutPath( 'mod_modulename', 'vertical'));
}
else {
modModulenameHelper::changeToHorizontal($position);//to change position in database to middle
require( JModuleHelper::getLayoutPath( 'mod_modulename', 'horizontal'));
But I am not getting the correct output. It is loading the respective modules based on the condition. But the position is not assigned at first. And if I press Ctrl+F5 or refreshes, the page will be loaded with the desired output.
Why is this happening? Any Solution??
The problem is that you are changing the position after the fact. By the time you are changing the position, Joomla has already assigned the module to a position. It's an order of operations thing.
Instead, why not just use 2 instances of the module? Rather than going through this trouble, simply add a parameter to the module that allows you to select horizontal or vertical, then assign one to the home page menu item and another to the rest of the pages. This would also allow for putting the module in other positions instead of hard coding it in to the module.
