I accidentally inserted a tag with some single quotes in them in a series:
> show series
key
---
sensor,boardid=b'5ddd2d00'
sensor,boardid=living_room
and I can't get rid of them. I've tried
drop series from sensor where boardid="b\'5ddd2d00\'"
drop series from sensor where boardid="b'5ddd2d00'"
drop series from sensor where boardid='5ddd2d00'
but the series is still there.
how to remove it ??
I found a solution, but don't like it, via a regex
drop series where boardid =~ /5ddd2d00/

Field codes:
Data:
Expected result:
Actual result:
I was thinking about where I should tweak the codes to fix the issue that the first column of each has three records as other columns do.
Also, a new class name (i.e. 1A, 1B) should be added to the second sheets (i.e. the second and fourth pages).
Thanks in advance for any help!
You need something more like this:
There were two problems - a change of class causes a page break, so at that point you can't rely on on the { =mod({ MERGESEQ },3) } = 0 to show you the right place to break next. Because a column break can also cause a page break, you also have to keep count of the columns to ensure that you can insert the class name every time you have a new page.
An advantage of doing it this way is that you can easily change the number of columns and rows per page.
(I have put one other thing in there, because strictly speaking you need to initialize Class1 when you start the merge).
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 a table which consists of 17025 rows. When I try to display the table, the whole table displays. But I want it in small parts. How do I make it display in small parts.
Type more on at the MATLAB command prompt. Subsequent output will be paused after every screenful.

I usually check my variables in these ways:
Suppose that we have a variable called A=rand(1000,1000).
1.we can display a part of A by calling A(127:130,241:243), to show the specific part of it.
>> A(127:130,241:243)
ans =
0.8152 0.0674 0.5609
0.1977 0.3906 0.6491
0.3288 0.1255 0.7478
0.9176 0.4253 0.5111
2.double click the name of the variable in the Workspace, so we could check it in Variables.
3.if your data only contain few columns, I recommend you to draw them in a figure and view them by dragging a Data Cursor in the picture.
SampleCode:
A=[1:1:200; 250:-1:51];
plot(A')
However, only the first option could display matrix on command window, but 2&3 is much faster since we don't know which part to display.
I have the following chart
I have created a parameter called IO OR LINE with two values: IO and LINE
then created a computed item called IO DRILL DOWN which is defined as:
if ([IO OR LINE] == 'IO') then [IO] else [Line Item] end
where the IO and Line Item are two dimensions
In the parameter drop down, if I choose LINE, I will get the chart
My question: I want to do the operations above but by clicking on the blue line in the first chart which will drill down as shown in the bottom chart? I don't like the parameter drop down solution
You could get this effect by:
generating 2 identical dashboards, one with the single line and
the other with the detailed view
Set up a Filter Action for when you click on the blue single line it takes you to the other dashboard with the multi-lines. If the dashboards are exactly the same and the performance is quick, this will give you what you are describing but it's a bit of an illusion.
At first, I thought you could do this somehow with layout containers and filter actions, but I got stumped when it came down to hiding the original view. https://www.interworks.com/blog/dwyers/2012/05/10/using-layout-containers-hide-views-your-tableau-dashboard
I've created a BIRT report in Eclipse (Juno) using BIRT v 4.2. The report has four tables, all tables are contained within grids. When I preview the report all the data displays properly, but if I select run as .pdf only a 2-3 rows of each table are displaying. I can export the report as html, xls and view it in web viewer without an issue. Has anyone else experienced this? (I've validated the sizing of the grid and tables).
I had the same issue and to overcome the problem I simply increased the size of the grid to fit the page manually.
If your rows are going to another page you need to script your way around that issue and you can find the solution here:
data cut when exporting as PDF
Update to cover broken link:
Quoting Michael Willians:
The PDF won't adjust like the GUI because of the fixed size constraint. To get a long, unbroken string to break, you'll have to add break characters of your own, either in a computed column or using a dynamic text box to write the script to break the long text up. Once you've broken the long text up, it should wrap to multiple lines within your PDF.
As an example, you could do something like this in a computed column, replacing "data1" with your column's name:
temp = "";
i=0;
while (i<row["data1"].length){
if (row["data1"].length - 10 < i){
temp = temp + row["data1"].substring(i,row["data1"].length);
}
else{
temp = temp + row["data1"].substring(i,i+10) + "\n";
}
i += 10;
}
temp;
To apply changes in the entire report, you could do a script in your beforeFactory method, stepping through your data elements, changing their expression. The easiest way would be to name your data elements, element1, element2, element2, etc., in the property editor. Then, you can easily access them by name, in your script.
Here's were you can edit the beforeFactory method, or any other:
You may also maintain a separate script with all your changes, as you can see on the resources directory:
