On our website http://tradingderivatives.eu/DAX-root.html, you can select a part of the tables and the graph will respond by zooming; the table event handers call the setVisibleChartRange method of the graph. Is there something similar for the graphs by Dygraphs?
I tried,among others, to google for "setVisibleChartRange Dygraphs" but nothing useful appears.
You do this by calling updateOptions. If you want to set the y-axis range, set valueRange. If you want to set the x-axis range, use dateWindow:
g.updateOptions({
dateWindow: [minDateInMillis, maxDateInMillis],
valueRange: [yAxisMin, yAxisMax]
});

I am using Chart.js 2.5.0 and wondered if anyone could give me some pointers on the following functionality requirement.
I have a bubble chart that for arguments sake contains tweets.
I have a list view next to the chart that display the tweets. Connected to this is the ability to filter, so it will only display tweets with specific string value the user inputs.
What I would like to do is when the user utilities the filter, it only shows the bubbles corresponding to the filtered result. I am passing the pointIndex and the datSetIndex into my table. However, I am really struggling in working out how to update the chart so it hides the bubbles that are not matching the current filter output.
Any suggestions?
This doesnt solve my entire issue as Im using Vue which seems to be causing issues with updating the chart. However if you are using plain chart.js the blow fiddle gives one way to hide specific or all points

I am creating an excel sheet with following Data Validation drop down list.
NA
Done
(add some formula here)
Basically, i will be able to select either plain text "NA"/ "Done" from the dropdown list. But sometimes, I want the user to be able to calculate some values based on the cell respective to the row selected so, I want to have one formula as a choice inside the data validation dropdown list. Is this possible?
Data Validation List Source
When I click on Formulae option, it should execute the formula with respect to the cells in that Row
But currently, the formula that i put in doesn't execute, instead it will just show the whole formula in the cell when activated.
1)How can i make it so that when i select the formula from data validation list, it will execute it instead of filling up the cell with it?
2)How do i set the formula so that it will be using the cell from the current Row? (for example, if i am using the data validation List in N60, the formula should adapt itself to use the cell (let's say A60?).
I may not be able to help with the second part, but I was seeking an answer to the first and discovered a solution/workaround using Name Manager.
First, in Formula > Name Manager, create a new reference (the "refers to" will contain whatever formula you are wishing to ultimately display in the validation list. For this example, we use the formula reference "=IF($H54=..." and Name it "UniqueName"
Now, we go into Data Validation, Select List, and input the three items we want displayed in the list, with an equals sign preceding our newly named reference: ie. "NA,Done,=UniqueName"
Note: You can't start with the =UniqueName or validation will try to read it all as a formula and fail.
This method will allow the user to display "NA", "Done", or "=UniqueName" in the cell; if "=UniqueName" is selected, the cell itself will interpret this as a formula and execute it accordingly, displaying the results of "=IF($H54=...", or whateverelse you have designated to use as a named formula.
If it's too late for yours, I hope this helps someone else who may face a similar problem.
While I think I know what you're trying to say. Why don't you just use an IF formula to evaluate everything instead of selecting a drop down for every row manually. You already had it partially solved using IF. Just need to add the criteria for a "Done" and an "NA"
=if(A1="date","Done",if(A1<"date","NA",if(something else until you have all your catergories))
Just going to piggyback off of Mark's response.
If you really needed your named formula to be the first selection in the list, you can setup your list with a leading comma like so:
,=UniqueName,NA,Done
That worked out for my use, and there was no null item listed in the Data Validation drop down. Hope that helps!
I’m getting crazy with Pro Motion table and I cannot find any discussion about this online.
I’m using a PM::TableScreen and I need to have selectable table rows. I manage the raw selection in an array but I don’t know how can I get the cell object to call cell.accessoryType = UITableViewCellAccessoryCheckmark if is selected or cell.accessoryType = UITableViewCellAccessoryNone if not selected.
Here is the gist of my screen: I try to intercept the cell passing a value in the arguments (row) but I cannot find a method to get the cell object.
In my original idea the place for the selection is inside my tapped_cell method byt maybe there is a better way to manage a multiselection.
My Gist
You don't want to memoize the table data. I've created a pull request with the fix:
https://github.com/robypez/rm_quiz/pull/1
Hard to summarize here, although I know Stackoverflow doesn't like us relying on links.
I have a situation where I'm using the IEditorDataFilter interface within a custom UltraGrid editor control to automatically map values from a bound data source when they're displayed in the grid cells. In this case it's converting guid-based key values into user-friendly values, and it works well by displaying what I need in the cell, but retaining the GUID values as the 'value' behind the scenes.
My issue is what happens when I enable the built-in group by functionality and the user groups by a column using my editor. In that case the group by headers default to using the cell's value, which is the guid in my case, so I end up with headers like this:
Column A: 7F720CE8-123A-4A5D-95A7-6DC6EFFE5009 (10 items)
What I really want is the cell's display value to be used instead so it's something like this:
Column A: Item 1 (10 items)
What I've tried so far
Infragistics provides a couple mechanisms for modifying what's shown in group by rows:
GroupByRowDescriptionMask property of the grid (http://bit.ly/1g72t1b)
Manually set the row description via the InitializeGroupByRow event (http://bit.ly/1ix1CbK)
Option 1 doesn't appear to give me what I need because the cell's display value is not exposed in the set of tokens they provide. Option 2 looks promising but it's not clear to me how to get at the cell's display value. The event argument only appears to contain the cell's backing value, which in my case is the GUID.
Is there a proper approach for using the group by functionality when you're also using an IEditorDataFilter implementation to convert values?
This may be frowned upon, but I asked my question on the Infragistic forums as well, and a complete answer is available there (along with an example solution demonstrating the problem):
http://www.infragistics.com/community/forums/p/88541/439210.aspx
In short, I was applying my custom editors at the cell level, which made them unavailable when the rows were grouped together. A better approach would be to apply the editor at the column level, which would make the editor available at the time of grouping, and would provide the expected behavior.
Using the Pie Chart ( http://code.google.com/apis/visualization/documentation/gallery/piechart.html ), is there anyway I can add/remove a data after the page was loaded?
For example, after a user click on a link I want to be able to remove one of the parts of the pie and when he clicks another link I want to add a new part.
Thanks.
Joel
Yes, it is possible. I've thrown together an example on JsFiddle. It's probably not exactly how you would do in a production environment but it should give you an idea.
Basically what I do is:
Make the DataTable and PieChart accessible from outside the drawChart() function (or whatever your draw method is called)
Use the removeRow() method on the DataTable object
Redraw the chart.
Joel, I did what you asked using a ckeckbox instead of links. When the checkbox has unchecked, I called data.removeRow(data.getNumberOfRows()-1) as jensgram points out. And when it was checked I called addRow(theDeletedRow).
Just take care that the added/removed row should be the last one of the RataTable (removing the first row doesn't make all other elements in the array go up), to keep the deleted value in a variable so you can add it again later, and try to specify colors in your options, so each part of the pie doesn't change of color (it gives the appearance that it is a completelly different pie, instead of the same one without just one part).
