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.

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 show some data in a bar chart and stacked bar chart using JavaFx. I am using 4 series into which I populate the data, using eclipse oxygen.
I use series1 and series2 in the Bar Chart.
I use series1, series2, series3, and series4 in the Stacked Bar Chart.
I have created my screen using the JavaFx Scene Builder. Populate the scenes and displaying the data. My problem is that I am not able to show both the graphs at the same time. Only the latter gets populated, depending on the order of the population. The extra bit I have added is that the graphs expand on a mouse enter event and then reduces to the orginal size on the mouse exit event.
Can anyone help me by pointing out what I am doing wrong?
My code is as follows
#FXML
private void bcsbg_mouseentered() {
if (!clickEntered) {
clickEntered = true;
prefWidth = bcByGroup.getPrefWidth();
prefHeight = bcByGroup.getPrefHeight();
bcByGroup.setPrefSize(1500, 900);
gXAxis.setPrefHeight(Region.USE_COMPUTED_SIZE);
gXAxis.setPrefWidth(Region.USE_COMPUTED_SIZE);
gYAxis.setPrefHeight(Region.USE_COMPUTED_SIZE);
gYAxis.setPrefWidth(Region.USE_COMPUTED_SIZE);
gXAxis.setVisible(true);
gYAxis.setVisible(true);
gXAxis.setLabel("Value");
gYAxis.setLabel("Question");
gXAxis.setTickLabelsVisible(true);
gYAxis.setTickLabelsVisible(true);
gXAxis.setTickMarkVisible(true);
gYAxis.setTickMarkVisible(true);
sbcByAll.setVisible(false);
} else {
clickEntered = false;
bcByGroup.setPrefSize(prefWidth, prefHeight);
gXAxis.setPrefHeight(0);
gXAxis.setPrefWidth(0);
gYAxis.setPrefHeight(0);
gYAxis.setPrefWidth(0);
gXAxis.setVisible(false);
gYAxis.setVisible(false);
gXAxis.setLabel("");
gYAxis.setLabel("");
gXAxis.setTickLabelsVisible(false);
gYAxis.setTickLabelsVisible(false);
gXAxis.setTickMarkVisible(false);
gYAxis.setTickMarkVisible(false);
sbcByAll.setVisible(true);
sbcByAll.getData().clear();
sbcByAll.getData().addAll(series1, series2, series3, series4);
}
bcByGroup.getData().clear();
bcByGroup.getData().addAll(series1, series2);
}
The problem here is not in your code, but in the way the chart API is written. (I'm not normally a fan of criticizing languages or standard libraries, but parts of this API appear to have been written by an unsupervised intern with a particularly bad hangover.)
The XYChart.Data class keeps a reference to the node that displays the data. (This fairly obviously violates the most basic tenets of MVC, and makes separating the data into a different class completely redundant.)
Consequently, if you try to use the same data in two charts, the same node tries to appear in two parents, which is not allowed, and you only see the visualization of the data in one place. Unfortunately, you need to replicate the data for each chart.
Thank you, Dave. You are right. I did not go through the standard documentation on the XYData.Chart to notice that this object would be attached to the node in which the data was going to be displayed.
I was really hoping to avoid replication but the code does work as soon as the data series is replicated and attached to the different charts.
As mentioned by Dave,

Please go through the standard documentation provided in Dave's link.
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.
I'm new to FusionCharts.
I have generated a pie chart with slice, my question is:
When I click on the slice in the pie chart, I need the label name of the slice.
How can I write the on click event and get the name of label?
I don't much about charts and such, I'm fine using Word for this. But in 2D Graphics I've learned you can use
...contains(shape)
...intersects(shape)
To see if shapes are inside eachother (to contain) or if they overlap eachother (to intersect).
When adding a mouseListener, you can use
e.getX() and e.getY()
to get the current X and Y position of mouse on screen.
So something like
for (pieChartPieces p: piece)
{
if (pieChartShape.contains(e.getX, e.getY))
{
//* Some kind of notifier for user pops up here.
}
}
Check out this fiddle here
It uses "dataplotClick" event to retrieve the label of the pie slice.
You have to use link attribute, as seen here.
"link": "JavaScript:populate('411');",
See the jsFiddle.
Don't forget to implement the populate() with the whatever you need to do.

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)
