I am new to Grafana and using a PostgreSQL data source for getting data and plotting the graph using the query results. I am trying to plot a time series graph where my data points present in the database varies every 10 seconds
Currently, in grafana the x-axis interval is showing 1 min interval tick mark. How do I label the X-axis such that it display 10 seconds tick mark?
Please suggest any available option or process to show seconds tick in X-Axis

Right now I am passing the list of two data's Timer1 and FP7 and the wave is also coming. But now I want to set this in Intervals of 10 seconds. I am using syncfusion Library and reffering this This Link. But I am not able to set Intervals. Can anyone please help me with this or Direct me to any reference where this is done.
Query 1: How to set Minimum and Maximum Values of x and y axis in Flutter Charts.
You can set the minimum and maximum of the x and y axis with the help of minimum and maximum properties in the axis. You can use the visibleMinimum and visibleMaximum properties of the chart axis too and these properties are used to set the minimum and maximum visible range of an axis.
Query 2: I am passing the list of two data's Timer1 and FP7 and the wave is also coming. But now I want to set this in Intervals of 10 seconds.
Add a data point at every 10 seconds interval, you can simply set the duration value to 10, as shown in the code snippet below.
Essentially I have a graph on my report. See attached image. The X axis is a duration in seconds. It is possible in Crystal 2008 to get the bar graph segments to have a label with the converted seconds to HH:MM:SS? Essentially turning 60 seconds into 00:01:00 on the label?
In the model I'm working on, ticks are months, and line plots are updated once every year, i.e. every 12 ticks. As ticks accumulate, the scale within the graph changes, of course, and the number in the lower right corner of the plot increases. This number reflects the number updates that have been made to the plot--i.e. the number of years. The number is the number of years that can be represented on the plot given its current scale.
Is there a way to change this number, without changing the rest of the plot, and without changing the idea that ticks are months? It would be convenient for this maximum x-axis value to show the number of months--i.e. ticks that could be displayed, even though the plot is only updated every 12 ticks.
Use the set-plot-x-range primitive. http://ccl.northwestern.edu/netlogo/docs/dictionary.html#set-plot-x-range
I have some energy 24 hour consumption data of many days.
Plotting a specific day gives me vertical axis of consumption and horizontal axis of time.
I would like to plot for lets say 1 year.
If I use "hold on/off" command, it plots all days together on top of each other.
How can i plot in a way that for the second day, the plots goes to the continue of the first plot (horizontal axis extends automatically)? So, when I have the complete plot, it shows 365 days of energy consumption based on hour. It's like the horizontal axis is repeating while the vertical axis is updating. I'm talking about MATLAB.
You can still use hold on and plot each day separately (if I understand your question properly, this is what you want, separate plotting). Simply make sure your x-axis values are correct. So e.g. if you have one measurement value per hour, the plot day 1:
plot(1:24,valDay1,'k-')
then for day 2:
plot(25:48,valDay2,'r-')
etc. This will line things up correctly. Also, consider using a datetime as x axis values
So, I found my solution which is very simple. I don't know how it didn't occur earlier.
I just had to use ";" and that's it.
Like this:
DAY=[day1;day2;day3]
plot(DAY)
So I am doing some ECG analysis in MATLAB and so far I have detected the key features as shown in the figure below :
This is the ground truth :
So how do i replot the first figure such that the x axis ranges from 0 to 10 (as shown in the second image)
I want to do this so that I can measure the time duration between the Q(the red cross) and the S (the peak at the minimum marked with a circle).
So essentially I want to
1) Calibrate 3600 samples into 10 seconds
2) Using the above scaling factor, be able to automatically calibrate any number of samples into the relevant seconds.
Thanks.
How did you plot the first figure? If you did not provide any x-axis, as in plot(ecg), the x-tick labels will be enumerated consecutevly in intervals of one. If you do know the corresponding time points t of ecg, you can use plot(t, egg);.
Since you know the sampling rate and assume consistent intervals between each data point, you can generate t yourself by t = 10.0 / 3600 * (0 : length(ecg)-1). This will create an array with length(ecg) elements starting at 0, with 10.0 per 3600 data points, for any length of ecg.
To align the horizontal axis limits more nicely than in the first plot, you can then also use xlim([0, t(end)]).
