I have a datetime series in Highcharts. The incoming data has some missing dates. Highcharts, by default, interpolates for those missing dates. I want it to interpret as if the data for those dates is 0. One way, obviously, is to add null data for these dates in my input data to Highcharts. Is there a better way to do this?
You need to set ordinal parameter as false.
You could set connectNulls to false. This will cause a break to appear in the line (if you are using a line).

Im new on Tableau Desktop.
I was starting to import data from a csv. file.
Some columns don't display decimal number, but instead, null value.
And I check, format is the good one (number with decimal).
In my csv. file, I can see my column with values :
And in Tableau :
Sometimes, data appears and sometimes not, that's weird.
So, What option do i choose ?
Thanks in advance.
Your data range is the issue here. You can right click on the Y-axis and edit the axis
I wanted to generate dates with wrong values like 30/02/2022. How to do it?
I used generate rows step in transformation with add sequence and calculator but it is showing all values correct. I want to include incorrect values to filter out it in next step.
I want to build a line graph, and I have missing dates in my data. I would like to get value 0 for the missing dates.
With the option 'Show Missing values', all dates are shown in the graph. But the missing dates do not have any values but they appear and the line passes over them.
Values for missing dates are not real NULLs. And therefore, I can not use functions like IFNULL or ZN to transform NULL values to 0, because it is not a real NULL. Do you know how to solve the problem?
Thank you!
Create a calculated field for measures in your graph:
IF [Dates]=NULL THEN 0 ELSE [Measure]
Use this calculated field instead the original measure.
Use the below calculated field and then click on date field pill and choose the option "show missing values"
ZN(SUM([Amount])) * (IIF(INDEX()>0 ,1, 1))
I am attempting to use the ZN() function to detect any NULL values, but the measures I need to use are categorical.
They can either only hold one of two values (Valid or Invalid) or be blank.
Is it possible for Tableau to treat these categorical values as numerical?
My first thought was to use a factorisation-type function, like the one in R, but I am not aware of any such function in Tableau.
Can this be achieved?
Create calculated field with following formula
CASE [YOUR_FIELD]
WHEN NULL THEN 0
WHEN 'Invalid' THEN 1
ELSE 2 END
I am very new to MATLAB. I am sorry if my question is basic. I am using "printmat" function to show some matrices in the command console. For example, printmat(A) and printmat(B), where A = 2.79 and B = 0.45e-7 is a scalar (for the sake of simplicity).
How do I increase the precision arbitrarily to seven decimals? For example: my output looks like 2.7943234 and B = 0.00000004563432.
How do I add a currency (say dollar) figure to the output of printmat?
How do I add a percentage figure (%) to the output of printmat?
Note: The reason I use printmat is that I can name my rows and columns. If you know a better function that can do all above, I would be glad to know.
Regards Mariam. From what I understand, you would like to display the numbers and show their full precision. I am also newbie, If I may contribute, you could convert the number data to string data (for display purposes) by using the sprintf function.
I am using the variable A=2.7943234 as example. This value will not display the full precision, instead it will display 2.7943. To show all the decimal tails, you could first convert this to string by
a = sprintf('%0.8f',A);
It will set the value a to a string '2.79432340'. The %0.8f means you want it to display 8 decimal tails. For this example,%0.7f is sufficient of course.
Another example: A=0.00000004563432, use %0.14f.
A=0.00000004563432;
a=sprintf('%0.14f $ or %%',A);
the output should be : '0.00000004563432 $ or %'.
You could analyze further in https://www.mathworks.com/help/matlab/ref/sprintf.html
You could try this first. If this does not help to reach your objective, I appreciate some inputs. Thanks.
The printmat function is very obsolete now. I think table objects are its intended successor (and functions such as array2table to convert a matrix to a table of data). Tables allow you to add row and column names and format the columns in different ways. I don't think there's a way to add $ or % to each number, but you can specify the units of each column.
In general, you can also format the display precision using format. Something like this may be what you want:
format long
