I am using a combined chart (Stacked Column + Line) for my application. Is it possible to change the line plotting?. (somewhat like shown in RED in the image). If yes then how is it possible?
I'm sure you already know the VIZ documentation where you can find all possible properties of VizFrame. As far as I know there currently is no way to get the behavior you're asking for except for writing your own lineRenderer (vizProperties.plotArea.lineRenderer). There is one alternative line plotting mode available which is smoothening it but I'm sure thats not what you want.
However you could use a second series of column chart instead. Just use a standard column chart and add two data series instead of one. I think this would show the exact information you're trying to get with the current diagram just no connection between them.

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 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.
Plain and simple, is it possible to do a bar chart like this one.. using google chart ?
I have no code to show you because is very simple to do bar chart but not sure if is possible to generate a difference arrow. (this graph is from Think Cell)
The closest thing I am aware of is Diff Charts. They aren't nearly as explicit in marking the change, but they are a way to visually display the change in a data set.
Using DiffCharts requires to separate google.visualization.DataTable instances with the old data an new data. You then call the computeDiff(oldData, newData) method on the chart instance and it will give you a new DataTable instance that you can use to draw the diff chart.
I am asking to the StackOverflow for the first time.
If I rude to you, Tell me it. I will fix it.
Thank you.
Asking...
In the BCG Library. Using Visual Studio 2012, MFC.
I want to control the display of data range in the chart of historical.
When I call below functions.
CBCGPChartAxis::SetFixedMaximumDisplayValue
CBCGPChartAxis::SetFixedMinimumDisplayValue
CBCGPChartAxis::SetScrollRange
CBCGPChartAxis::EnableScroll
CBCGPChartAxis::EnableZoom
CBCGPChartAxis::SetAlwaysShowScrollBar
The chart just worked once.
And then, The chart seemed calling CBCGPChartAxis::SetAutoDisplayRange() automatically.
In other words. I don't want to call CBCGPChartAxis::SetAutoDisplayRange() automatically by the chart.
controlling the display range in a history' chart.
As far as I can see in the source code this function is called from serveral places. Maybe the easiest method to block this function is to call CBCGPChartSeries::ReplaceAxis and replace the automatically created axis with you implementation, that may ignore SetAutoDisplayRange.
If this doesn't help or as a method for further investigation:
Set a breakpoint and look into the callstack to see who calls this function and when this function is called. Again: As far as I understand the source code the function is called automatically when something changes in the chart.
CBCGPChartAxis* pXAxis=***;
pXAxis->EnableScroll();
pXAxis->EnableZoom();
pXAxis->ShowScrollBar();
pXAxis->SetFixedUnitCount(20,1);
20 means the totle number of V grid line in every visible range and 1 menas there is one point in a single range of every grid.
Might be your wanna.
I've got a kinda requirement in which there is a kinda graph (static picture) on a page. In that picture I need to plot some points dynamically. That means using a shape filled with blue color. The number of points is floating depending upon the number of applicants choosen. How can I make it work or how can I add new elements to report at runtime. Am working in ASP.nET using VB and the AR version is 6.2
If I have understood your query right,then you want to plot some points depending on the dynamic data.
A suggestion would be to make use of Chart control in report. The chart can be bound to anything from a list to an array and the data can be changed dynamically from time to time.
Moreover,you can set the backcolor and other properties of the Chart control to give a look and feel of your choice.

Sorry if my question makes any confusion.. Actually I was able to make that. So am just sharing that code if it helpful for someone else.. I put this to the report start event. (We are not permitted to make this in details event)
Dim pic As New DataDynamics.ActiveReports.Picture
pic.Image = System.Drawing.Image.FromFile(HttpContext.Current.Server.MapPath(String.Format("~/images/circle.gif", cl)))
pic.SizeMode = SizeModes.Zoom
Detail1.Controls.Add(pic)
